Light Truck Megashifter

Part Number 80680

The B&M Light Truck Megashifter shifter is designed to be used in most light trucks equipped with most popular three speed or four speed automatic transmissions. Your B&M Megashifter comes equipped with neutral safety and backup light switches, transmission brackets and levers and a five foot shift cable. Optional shifter cables in 2 ft.(#80830), 3 ft.(#80831), 4 ft.(#80832), 8 ft.(#80834), 10 ft.(#80835) and 12 ft. (#80836) are also available. To use the B&M Light Truck Megashifter with the Ford AOD transmissions you will need the optional accessory kit #40496.To use the B&M Light Truck Megashifter with the GM 4L60E and 4L65E equipped with a PRNDL switch you will need optional accessory kit #75498 otherwise you can use the GM bracket supplied.

This shifter has adjustable height mounting brackets so that it can be installed at the best height for your truck. Because the front and rear mounting brackets can be adjusted separately, it can also be install on an angled or sloping floor with the shifter mounted flat.

Please read the instructions and review the illustrations thoroughly before beginning the installation.

The mechanical components of this shifter are precision made and assembled at our factory. Any modification or disassembly of these parts can cause the shifter to malfunction and will void the warranty. You should disassemble only those items outlined in the instructions.

The vehicle should be about 2 feet off the ground for ease of installation. Use jack stands, wheel ramps or a vehicle lift. Make sure the vehicle is firmly supported before attempting to work on it. IMPORTANT: If your vehicle is equipped with a locking steering column, securing the column lock lever in the engine compartment in the full up position will allow the steering wheel to be locked and unlocked and the ignition key to be removed.

WARNING: This allows the steering wheel to be locked WHENEVER the ignition key is turned to the “lock” position WHILE THE VEHICLE IS MOVING, OR AT ANY OTHER TIME. Securing the steering column lock lever in any other position will both PREVENT the steering wheel from locking and the removal of the ignition key.

INSTALLATION

NOTE: If you are installing this shifter with

a GM four speed automatic transmission, you must remove the blocker pin and the two e-clips indicated in Figures 1 and 3. Removing this blocker pin gives the shifter four forward positions rather than three. For Ford AOD four speed transmissions do not remove this blocker pin and the two e-clips, since this transmission has only three forward positions. Also do not remove the blocker pin and the two e-clips for three speed automatic transmissions. STEP 1. Locate the shifter on the floor of the truck where you want it to be located. The mounting brackets can mount the basic shifter assembly 1-1/2" to 3-5/8" above the floor. Figure 2 gives the dimension of the shifter, so be sure that there is enough room where you will be mounting the shifter.

STEP 2. Remove the stock shift linkage; Column Shifters: Remove all rods, le-

vers or cables from the column and the transmission. Place the column shift lever in the Park position. Remove the pin holding the shift lever in the column and remove the lever assembly. If your vehicle is equipped with a locking steering column, secure the column lock lever in the full up position. WARNING: This allows the steering wheel to be locked and the ignition key removed WHENEVER the ignition key is turned to the Lock position WHILE THE VEHICLE IS MOVING, OR AT ANY OTHER TIME.

Console Shifters: Remove the shifter mechanism from the console. Disconnect the rod or the cable from the transmission. Remove the cable bracket if equipped. If there is a cable or linkage from the console shifter or the transmission to the steering column lock, it must be blocked in the Park position as described above. NOTE: The shifter installation may require console modification or complete console removal depending on the space available in your vehicle. STEP 3. Assemble the mounting bracket as shown in Figure 1. Be sure that the end plate with the wide slot on top is to the front and that the top plate has the three holes at the front. Assemble the bracket with the four 1/4-20 x 3/4" screws finger tight. Put flat washers on both sides of the brackets and a lock washer under the nut.

Pull the carpet away from the floorboard where the shifter mounting bracket is to be located. Place the shifter on the mounting bracket and slide the front and rear brackets up or down to get the desired height for the shifter. Tighten the four screws on the bracket. If the vehicle has a bench type seat, move the seat to the full forward position. With the stick shifted to the rearmost gate position. Locate the shifter for ease and convenience of operation (See Figure 2). Make sure the trigger and the T-handle clear the dash with the shifter in the Park position. Mark the position of four mounting holes for the bracket assembly on the floor. STEP 4. Drill four 9/32" mounting holes where marked. Temporarily mount the shifter to the mounting bracket and bolt the bracket to the floor. If the floor is not flat, bend the tabs at the end of the front and rear bracket. Mark the location for the shifter cable hole in the floor. The hole will be 1" inboard of the left front mounting bracket to floor bolt and between 2-1/2"

and 3-1/2" ahead of this bolt. (The hole will be 3-1/2" ahead if the bracket is at maximum height and 2-1/2" ahead if the bracket is adjusted to minimum height. Drill or cut a 1-1/2" diameter cable hole in the floorboard. NOTE: Some floorboards are extremely thin and will not adequately support the shifter mechanism when bolted to the floor. For those vehicles we recommend that you fabricate a stiffener plate for additional strength. STEP 5. Remove the mounting bracket assembly. Tighten the four screws securely. At each end, drill a 1/4" hole through one of the locking holes in each end of the bracket into the top plate. Put a 1/4" screw and a lock washer into each of these holes to lock the bracket together. Attach the shifter to the mounting bracket with four 1/4-20 X 3/4" screws and lock washers. STEP 6. Install (but do not secure) the carpet back to it’s original position. Cut holes in the carpet for the mounting holes and cable. DO NOT use a drill bit to make the holes in carpet. STEP 7. Assemble neutral safety and reverse light switches to the bracket using two #4-40 x 1" screws and nuts, as shown in Figure 1. Beware, over tighten- ing the switch attachment screws will crack the switch housings. Install the switch assembly on the shifter. To adjust the switches, loosen the screws and slide the switches in or out as required, then retighten the screws. STEP 8. Install the cable on the shifter as shown in Figure 1. The cable attachment tab should be bolted to the outside surface of the shifter base using a 1/4" x 1/2" hex screw, lock washer and nut. Install the e-clip that secures the cable to the cable pin. STEP 9. Just before the final installation of the shifter in the vehicle, attach the indicator cable to the side of the shifter as shown in Figure 3. The indicator cable bracket is secured to the shifter mechanism with two #6 x 3/4" sheet metal screws and #6 washers, the eyelet on the end of the indicator cable is secured to the cable pin by a supplied small e-clip. STEP 10.Install the shifter mechanism into the vehicle. Slide the shifter cable through the carpet and the hole in floor. Bolt the shifter down using four 1/4-20 x 1-1/2" full thread hex screws, nuts, lock washers and flat washers. If the mounting bracket does not sit flat of the floor, the tabs at the end of the mounting bracket can be bent so that they will fit the floor.

ROUTE THE CABLE AS SHOWN IN FIGURE 4, AVOID SHARP BENDS WHICH WILL KINK AND DAMAGE THE CABLE.

Use cable clamps or tie wraps to secure the cable housing to the chassis to avoid contact with hot engine or exhaust system. STEP 11.Seal the hole where the cable goes through the floorboards to prevent

air or water leakage. A putty type sealer can be used. For General Motors vehicles go to Step 12, for Ford vehicles got to Step 17, for Chrysler vehicles go to

Step 23.

GENERAL MOTORS

STEP 10.If you have not already done so,

remove the stock selector lever nut and the selector lever from the transmission. Discard the stock lever and the stock shifter linkage. Install the B&M selector lever in position using the stock selector lever nut (See Figure 5). Torque the nut to 23 lb.ft. The lever should move smoothly from front to rear with a positive click in each gear position. STEP 11.Remove the two transmission oil pan bolts from the middle of the left side of the oil pan. Install the cable bracket in position (See Figure 5). The bracket must be installed with two spacers between the pan and the bracket. (If your transmission is equipped with a cast aluminum oil pan, these spacers should be omitted. With a TH-400 with a cast aluminum oil pan the cable bracket may have to be modified.) Install the two 5/1618 x 1.00" bolts (Metric transmissions use the two 8mm x 25mm bolts) supplied and tighten to 12-13 lb.ft. Do not overtighten as this can damage the pan gasket. STEP 12.Route the shifter cable according to Figure 4. Avoid kinks and sharp bends and route the cable away from hot engine or exhaust parts.

Remove the two rubber boots, one large nut, and a large lockwas her from the threaded end of the shifter cable.

Figure 2

Slide the end of the cable into the cable bracket. Install the large nut and the lockwasher loosely over the end of the cable. Install the two rubber boots onto the end of the cable. Install the swivel on the threaded end of the cable and position it in the center of the threaded portion. STEP 13.Move the transmission selector lever by hand to full rear position (Low). Operate the shifter lever to the Low gear position (ratcheted all the way back). Adjust the large nuts on the cable so that the swivel will slide into the front hole on the selector lever. Tighten the large nuts completely. Be sure that the swivel will slide freely in and out of the hole in the

selector lever. Note: The shifter will not operate correctly unless the front hole in the shift lever is used.

Leave the swivel out of the hole and move the selector lever to Park, all the way forward. Also move the shifter to the Park position (all the way forward). Reinsert the swivel into the front hole in the selector lever. Check to see that the swivel will slide freely in and out of the front hole in the selector lever in this position. If it does not slip in freely, adjust the swivel slightly until it will slip into the hole in the lever.

Move the shifter back to the Low gear position and check that the swivel will still

slide easily in and out of the front hole in the selector lever. (If you do not use the front hole in the lever, it will be impossible to correctly adjust the cable.) Operate the shifter through all the gear positions. Check to make sure the swivel will slide in and out of the front selector lever hole in each gear position. The shift cable is now correctly adjusted. Install the cotter key supplied with the shifter into the swivel and spread the key ends.

If you have a problem, DO NOT FORCE THE SHIFTER, this will damage the cable, the shifter or the transmission. Simply start at the beginning and carefully check all your steps. STEP 14. On GM vehicles, the neutral safety switch may be located on the shifter (steering column or console), or it may be a mechanical interlock in the steering column that prevents the key from turning to the Start position unless the shifter is in the Park or Neutral position. Identify the type of neutral safety system you have. If the key will not turn to the Start position unless the stock shifter is in Park or Neutral, you have a mechanical interlock type, otherwise you have a neutral safety switch type. If you have a neutral safety switch, locate the switch and identify the neutral safety wires (engine will not crank unless these wires are connected together). With either type, disconnect the battery ground cable to prevent accidental shorts. If you have a neutral safety switch, disconnect and extend both wires from the GM switch to the switch on the shifter. If you have a mechanical interlock cut the wire that goes from the Start position on the ignition switch to the solenoid on the starter. This wire is usually a 10 or 12 gauge purple wire. Run wires

Figure 4

from both ends of the cut wire to the switch on the shifter. Put slip on terminals on the ends of the lengthened wire. Crimp the terminals onto the wires using a crimping tool or pliers. Connect the wires to the switch on the shifter. Tape the terminal connections and all other connections to prevent shorts. Reconnect the battery ground cable, disconnect the coil wire and set the parking brake. Check the switch operation by attempting to start the motor in each shifter position. The

starter must crank only when the shifter is in the Park or Neutral position.

Adjust the switch if required. Reconnect

the coil wire. Go to Step 27.

FORD

STEP 15. If you have not already done so,

remove the nut and lockwasher holding the downshift linkage onto the downshift lever shaft. The downshift lever is the outer lever on C-4, C-5, C-6 and AOD transmissions. Pull the lever off the shaft and allow the linkage to hang free. Remove and discard the stock shift linkage rods. Some C-6 and all (late) C-4 and C5 transmissions have a neutral safety/ backup light switch on the transmission

STEP 16. Install the B&M selector lever (See Figure 6 or 7). Note: The B&M lever

must point downward for proper operation. If the stock shift lever on your transmission points down, you will have to remove the lower part of the stock arm by cutting it off to clear the B&M lever (See Figure 6). Install the B&M selector lever onto the shift shaft of the transmission. Align the selector lever so when it points straight down it travels equal arcs in both directions from the center, then tighten the 1/4"-20 x 1 1/2" pinch bolt and nut. The lever should travel smoothly from front to back with a positive click in each gear position. Make sure the O-ring is in position on the downshift shaft and install the downshift lever in position on the shaft. Install the lockwasher and the nut and tighten securely. The downshift lever must operate smoothly. Reconnect the downshift linkage.

STEP 17. Cable bracket installation: AOD: Instructions for the AOD are in-

cluded with the optional installation kit #40496. C-4, C-5: Remove the two lower bolts from the rear servo cover. Install the cable bracket in position (See Figure 6). Install the two servo cover bolts as removed and tighten to 12-13 lb.ft. Do not overtighten as this can distort the servo cover. C-6: Remove the two transmission oil pan bolts from the left rear corner of the oil pan. Install the cable bracket in position (See Figure 7) with two spacers between the pan and the bracket. (If your transmission is equipped with a cast aluminum oil pan, these spacers can be omitted.) Install the two 5/16-18 x 1.00"

Locate and identify the neutral safety (the engine will not crank unless these wires are connected together), and the reverse light wires. Disconnect the battery ground cable before beginning to wire the neutral safety and reverse light switches. Reroute the wires to the B&M Megashifter. Strip 1/4" of insulation off the wires and install the supplied slip-on terminals. Crimp the terminals onto the wires using a crimping tool or pliers. Connect the neutral safety wires to the LOWER switch and the reverse light wires to the UPPER switch (See Figure 1) . Tape the terminal connections to prevent shorts. Reconnect the battery ground cable, disconnect the coil wire and set the parking brake. Check the switch operation by attempting to start the motor in each shifter position. The

starter must crank only when the shifter is in the Park or Neutral position. Check the backup light

operation when the shifter is shifted to the Reverse position. Adjust the switches if required. Reconnect the coil wire. Go to Step 29.

CHRYSLER

STEP 21. If you have not already done

so, loosen the pinch bolt on the throttle lever on the transmission. This is the lever on the small diameter shaft. Pry the lever off with a screwdriver and allow the linkage to hang free. Remove and discard the stock shift lever and the stock shift linkage. Install the B&M selector lever in position and tighten the pinch bolt securely (See Figure 8). Make sure the lever is not pushed down so far as to touch the transmission case. This will cause the lever to bind on the case. The lever should travel smoothly from front to back with a positive click in each gear position. Install the stock throttle lever in position on the small diameter shaft as removed and tighten the pinch bolt securely. The throttle lever must operate smoothly. STEP 22. Remove the two transmission oil pan bolts directly below the shift lever. Install the cable bracket in position (See Figure 8) with two spacers between the pan and the bracket. (If your transmission is equipped with a cast aluminum oil pan these spacers can be omitted.) Install the two 5/16-18 x 1.00" pan bolts supplied and tighten to 12-13 lb.ft. Do not overtighten as this can damage the pan gasket. STEP 23.Route the shifter cable according to Figure 4. Avoid kinks and sharp bends and route the cable away from hot

engine or exhaust parts.

Remove the two rubber boots, one large nut, and a large lockwasher from the threaded end of the shifter cable. Slide the end of the cable into the cable bracket. Install the large nut and the lockwasher loosely over the end of the cable. Install the two rubber boots onto the end of the cable. Install the swivel on the threaded end of the cable and position it in the center of the threaded portion. STEP 24.Move the transmission selector lever by hand to full forward position (Low). Place the shifter lever to the Low gear position (ratcheted all the way back). Adjust the large nuts on the cable so that the swivel will slide into the hole on the selector lever. Tighten the large nuts completely. Be sure that the swivel will slide freely in and out of the hole in the selector lever.

With the swivel in the selector lever, move the shifter to the Park position, as far forward as the shifter will go without forcing it. (The shifter has further travel that is used to reach the GM Park position but is not used on Chrysler transmissions. Trying to force the shifter will damage the cable.) The shift lever on the transmission should be all the way back. Check to see that the swivel will slide freely in and out of the hole in the lever in this position. If it does not slip in freely, adjust the swivel slightly until it will slip into the hole in the lever in both the Low and the Park positions. Operate the shifter through all the gear positions. Check to make sure the swivel will slide in and out of the selector lever hole in each gear position. Install the cotter key supplied with the shifter into the swivel and spread the key ends.

If you have a problem, DO NOT FORCE THE SHIFTER, this will damage the cable, the shifter or the transmission. Simply start at the beginning and carefully check all your steps. IMPORTANT: Do not force the shifter to over travel into the Park position. This will move the shifter into the GM Park position and will damage the cable or the transmission. STEP 25. Check the operation of the throttle linkage again. The linkage must operate smoothly with no bind. All transmissions using automatic valve bodies must have the throttle linkage connected and operating or transmission damage will result. STEP 26. Neutral Safety/backup light switch. ’66-’68: The neutral safety switch will continue to function normally. It will not be necessary to hook up the neutral safety switch wires on the shifter. Disconnect the battery ground cable before wiring the backup light switch. Locate the original backup light switch on the steering column or the console shifter. Run these wires to the top switch on the B&M

Megashifter (See Figure 1). Reconnect the ground wire and check the light for proper operation. Adjust the switches on the shifter if required. ’69 and Later: The neutral safety/backup switch is located on the transmission and will continue to function normally. It will not be necessary to connect any wires to the switches on the shifter. STEP 27. Check the operation of the throttle linkage again. Linkage must operate smoothly with no bind. All transmissions using automatic valve bodies must have the throttle linkage connected and operating or transmission damage will result. STEP 28. Neutral safety/backup light switch ’66-’68: The neutral safety switch will continue to function normally. It will not be necessary to hook up the neutral safety switch wires on the shifter. Disconnect the battery ground cable before wiring the backup light switch. Locate the original backup light switch on the steering column or the console shifter. Run these wires to the top switch on the B&M Light Truck Megashifter (See Figure 1). Reconnect the ground wire and check the light for proper operation. Adjust the switches on the shifter if required. ’69 and Later: The neutral safety/backup switch is located on the transmission

IMPORTANT

Before installing the T-handle onto the shifter put a little grease on the threads of the stick. The aluminum of the T-handle may gall on the threads of the stick and make it impossible to remove the T-handle from the stick. If this occurs it can cause the stick to break if you use excessive force while attempting to remove the T-handle from the stick.

and will continue to function normally. It will not be necessary to connect any wires to the switches on the shifter. STEP 29. Place the tower over the shifter mechanism until the bottom edge of the tower touches the floor. Put the shifter cover and the indicator cable through the opening in the top of the tower. Hold the tower level to the shifter with the bottom of the tower touching the highest surface on the floor it will come into contact with (See Figure 9). Use a ruler to measure the distance X from the underside of the tower to the tower mounting brackets on the shifter mechanism. STEP 30. Set a pair of dividers at the distance X, measured in step 29. Hold the tower level to the shifter mechanism with the bottom of the tower touching the highest surface on the floor it will come into contact with. Holding the tower in position, place one leg of the divider against the floor while the other touches the tower (See Figure 9). Using the divid-

ers, scribe a line around the tower that follows the contour of the floorboard. Remove the tower and trim at the scribe line using tin snips. Once the tower is properly trimmed, install it using two flat head sheet metal screws. The indicator cable should be routed out the top of the tower on the right side while the tower is being installed. STEP 31. Install the indicator light bulb in its socket on the shifter cover plate. Run a length of wire from the vehicle’s instrument light circuit to one of the wires. Connect the other wire to a good chassis ground. A shifter mounting bolt should be satisfactory. STEP 32. Snap the shift position window into the cover plate. The window snaps in from the top with tabs inserting into the slots at either end of the window opening. Place the shifter in the Park position then remove the T-Handle from the shifter. Place the cover plate over the stick and onto the top of the tower. Route the indicator cable as shown in Figure 10. (If the cable is not routed this way, the indicator may bind. Run the shifter through all of the gears to check the operation of the indicator. If the indicator needs adjustment, loosen the screws holding the indicator cable clamp to the cover plate and slide the cable bracket to adjust the indicator position. (Re-tighten these screws carefully since they are threaded into the plastic.) Attach the cover plate to the tower with four Phillips head screws. STEP 33. Slide the boot over the stick and install it into the cover plate. After the

OPERATION

The B&M Light Truck Megashifter nor- mally functions as a straight gate detent shifter from Park to Reverse to Neutral to Drive and as a ratchet shifter from Neutral to all the forward gears. Refer to the following instructions for proper operation: STRAIGHT GATE MODE: With the trigger in the upper position, the shifter functions in the STRAIGHT GATE mode. The handle travels in a direct line forward and backward from PARK to DRIVE. The trigger must be raised up to clear the stop gates while going through the gear positions. RATCHET SHIFT MODE: The RATCHET SHIFT mode allows firm, positive nomiss upshifts and downshifts through all positions from 1 (Low gear) to Neutral. To switch from STRAIGHT GATE to RATCHET operation, first operate the shifter to the Drive position. The trigger will snap down approximately 3/4". The shifter is now in the RATCHET MODE, Drive gear position. The shifter will only operate in the RATCHET MODE between Neutral and First, it will not ratchet to Reverse or Park. This is done to prevent accidental shifting into Reverse. SHIFTING IN THE RATCHET MODE: Move the shift handle forward or backward with a quick firm action until it hits the internal stops, and allow it to spring return to the center position. The shifter is now ready for the next shift.

To switch the shifter from RATCHET

MODE back to the STRAIGHT GATE

MODE, operate the shifter to the Drive gear position, pull up firmly on the trigger to engage the STRAIGHT GATE MODE and move the handle forward to Neutral, Reverse and Park. REMEMBER: To switch from the STRAIGHT GATE MODE to the RATCHET MODE or from RATCHET MODE to STRAIGHT GATE MODE you must be in the Drive gear position. Refer to the shift

indicator gear position. SPECIAL NOTE: If the instructions for operating your shifter seem complicated, DO NOT BECOME ALARMED. You will find that in actual use the shifter will be extremely easy to operate after a minimal amount of experience. Caution: The shifter is an important controlling mechanism of your vehicle and can create serious driving hazards when any part is loose, missing or misadjusted. After you have installed your B&M Light Truck Megashifter in the vehicle, we recommend you review the instructions to assure complete and proper installation.
