The Ranger Torque Splitter Two-Speed Overdrive has been the answer to gear splitting for nearly
two decades. This unit was designed and developed by Warner Gear Corporation in the late 1960s. We
purchased the unit in 1975, and have built hundreds of overdrive units since that time. The design has
changed over the years, but the performance has stayed the same.

If you have a truck equipped with a 4 speed transmission and are having difficulty
keeping the engine RPMs at peak range, then you need a Ranger Torque
Splitter Overdrive. The Ranger simply provides a gear between each of
your existing gears and converts your 4 speed to an "8 speed". When used
as a gear splitter, you will be able to keep the engine RPM loss at a
minimum, thus preventing the usual winding and lugging of the 4 speed
transmission and engine. This works great for both diesel and gas pickup trucks.

With your engine coupled to the Ranger Torque Splitter Overdrive, your power can
now be efficiently utilized with less engine wear, maintenance & downtime, and
dramatically improve fuel economy. A typical example would be a Chevy truck with a V8
engine and a 4 speed transmission that has an engine RPM of 2500 when driving 60 m.p.h. in 4th gear. This same truck, when
equipped with the Ranger Overdrive and traveling 60 m.p.h. in 4th gear overdrive will have an engine RPM of 1825. This is a
drop of 27% in engine RPMs for the same highway speed.

The Ranger Torque Splitter Overdrive has been designed for maximum ease of installation and requires no special tools. The
front of the Ranger simply bolts directly to your existing bellhousing. Your 4 speed transmission indexes directly into the back
of the Ranger. You will be required to have your driveshaft shortened by your local driveline specialist. The Ranger is 7-1/2"
long and will require the relocation of your 4 speed transmission shift lever.

The internal design of the Ranger Torque Splitter Overdrive consists of a T98 synchronizer coupled with precision helical cut
gears. The gear assembly is mounted on roller & ball bearings that will provide a maximum torque range of 420 ft./lbs. Each
unit is furnished with a shift control handle that has been designed for use in most pickup trucks. The splitting of gears does require
shifting of both the stock 4 speed shift lever and the Ranger shift lever. The clutch must be used when shifting the unit.

The Ranger is compatible with all manual transmissions whether in 2WD or 4WD. Since the location is ahead of the transmission

and transfer case, the overdrive and gear splitting capabilities can be used in 4WD. The installation of the Ranger in your vehicle
will not require the continual use of all eight forward gears. Depending on your requirements, you need not always use all eight
gears. A good example would be when you are in city traffic where you may choose to use only four gears--the choice is yours.

Whether loaded or unloaded, on the highway or in the city, the Ranger offers you the opportunity for a great investment that makes
your truck fit your driving requirements.

required. Note: We do not offer a 7-1/2"long input shaft option.

TOYOTA LAND CRUISERS:

adapters can be eliminated. Note: The earlier 3 speed Land

Cruiser can be mated to the Ranger Torque Splitter by using a special retainer, P/N 716222, with Overdrive P/N 760001M-27.

Special Note: The Ranger can be installed on 1987 and newer Land Cruisers. On these applications, we have found a few odd size input shaft

bearings that Toyota used. In order to use our overdrive unit, the front input shaft bearing of your transmission must be measured. (This will verity what
bearing index is necessary - a 3.544" diameter is standard). If your bearing diameter is 3.625", a special rear plate can be machined for this application.

VEHICLE INSTALLATION PROCEDURES

CHEVY, GMC, FORD & TOYOTA L/C

INSTALLATION PROCEDURES:

READ THESE INSTRUCTIONS CAREFULLY BEFORE BEGINNING!

1. Disconnect the battery cable.

2. Unscrew the molding at one door so that the carpet or mat may be

folded to the opposite side for access to the shifter.

3. Unscrew the boot and slide it upward for access to the top of the
transmission. Remove the shift handle knob and shift lever boot for
the transmission and (if a 4WD) the transfer case.

STANDARD BELLHOUSING

4. Remove the shift lever out of transmission by removing the stamped
metal piece from the base of the stick. NOTE: Some models simply

unscrew, while others come apart by pushing down and turning
approximately 1/4" counterclockwise. On Borg Warner T18 trans­missions found in some Ford products, it is necessary to remove a
small pin in the left side so that it does not fall into the transmission.

5. Place a clean rag in the top of the transmission so that dirt does not

get in during removal and reinstallation.

6. With the mat or carpet pulled to one side, remove the screw and bolts
from the tunnel housing and detach it. (Greater accessibility can be
gained by removal of the seat).

7. Jack up the vehicle and support solidly. Be sure to block any wheels
remaining on the ground. CAUTION: Never go under a vehicle

that is not solidly supported. Adequate jack stands are recom­mended. Before beginning work, always test a raised vehicle
carefully to be certain there is no danger that the vehicle will
fall.

8. Unbolt the U-Joints and remove the rear driveshaft (on 4WD

vehicles, the front driveshaft must also be removed). The rear
driveshaft must be shortened 7-1/2", and the front driveshaft must
be lengthened respectively. (On Land Cruiser installations with a
GM V8, no driveline modifcations are required).

9. Disconnect the speedometer cable. Because of the additional
length of the Ranger, it may necessary to lengthen the speedometer
cable. This may be accomplished in some cases by rerouting the
cable. If that isn't possible, then it may be necessary to have a new
cable made.

transmission. On most models, the rear of the engine and
transmission are supported by a crossmember bolted to the
frame, and then to the transmission with a cushion between
the crossmember and the transmission. It is essential that the
rear of the engine be properly supported before proceeding.

11. When you are certain that the rear of the engine is firmly supported,

remove the bolts in the crossmember and take it off.

13. When the jack has been securely fastened to the transmission,
remove the four bolts holding the transmission to the bellhousing.

14. Remove the transmission. This is an excellent opportunity to check
the condition of the clutch disc, pressure plate, throw-out bearing,
and pilot bearing. Replace worn parts if necessary.

15. Clean the transmission input shaft thoroughly. Measure the opening
in the bellhousing carefully, and then the outside diameter of the
bearing retainer on the Ranger Overdrive. SEE THE ILLUSTRA­TIONS marked "A". If the bearing retainer size is smaller or

larger then the opening in the bellhousing, please contact us
toll free at 1-800-350-2223. Both bearing retainers must fit snugly

for proper alignment of the transmission to the Ranger, and the
Ranger to the bellhousing.

16. Remove the front bearing retainer on the original transmission
carefully so as not to tear the gasket. Also, check the oil seal in the
base of the retainer and replace it if necessary. (The oil seal is not
supplied in the Ranger kit. The snout of the retainer must be cut off
and the seal must be retained. The normal cutoff location is .750".
However, we have had a customers require a longer length to retain
the stock seal. Make sure you cut enough off so that the snout does
not bottom out in the back of the Ranger.

Reinstall the retainer on the original transmission using the original
gasket and bolts (without lock washers). Lock washers will raise the
bolt head heights enough to cause severe damage and interference.
We recommend that you use "BLUE LOCTITE" for the bolts in place
of lock washers.

On Land Cruiser 4 speed installations, the Ranger uses the trans­mission front bearing for alignment. This step, as mentioned above,
is not necessary. Simply remove the front retainer and clean the front
of the transmission. On Land Cruiser 3 speed transmissions, our
bearing retainer P/N 716222 and seal P/N 716719 should be
used. The snout on this retainer must be shortened as list above.
