FIRST, READ INSTRUCTIONS CAREFULLY, THEN PROCEED TO INSTALL VALVE BODY BY
FOLLOWING EACH STEP INDIVIDUALLY.

It is suggested that you do all modifications for maximum performance.
STEP #1: Place transmission in park.
STEP #2: Remove drain plug and drain oil. Remove pan.
STEP #3: Remove modulator and small rod if so equipped.
STEP #4: Remove 2 bolts holding shift lever guide plate. NOTE position of shift lever and manual

valve. Also note position of the small spring that gives detent pressure for shift lever, (See
Fig. #1).

STEP #5: Remove six valve body bolts that hold valve body in place (See holes in new valve body

included). (See Fig. #2)

STEP #6: If transmission in car, hold one hand on valve body and carefully pry with screwdriver under

the Servo Tube connecting the valve body to the servo. (See Fig. #3)
STEP #7: Let valve body drop down towards the converter.
STEP #8: Remove E-Clip and Detent Bracket from old valve body.

Part #22997 & #22998 1 2/90,4/99

STEP #9: Place E-Clip and Detent Bracket on new valve body.
STEP #10: Remove Manual Slide Valve from old valve body.
STEP #11: Install Manual Slide Valve into new valve body.

Steps #12 thru #20 should be done for best results.

STEP #12: Remove front pump assembly.
STEP #13: Remove front drum assembly.
STEP #14: Remove planetary assembly.
STEP #15: Remove rear clutches.
STEP #16: Remove rear piston.
STEP #17: The back of the case will have a small hole in it. Enlarge to 1/4”.
STEP #18: Rear piston - drill a 1/16” bleed hole near outer edge of piston.

1/16” hole to be drilled.

STEP #19: Reinstall rear piston with bleed hole towards top of case and set rear clutch clearance to

0.080-0.100 using five clutches. It will most likely be necessary to switch around different

thickness steels or machine piston for proper clearance.
STEP #20: Reassemble rest of transmission to stock specifications. Suggest a #22043 Direct Clutch

Steel Hub for added dependability.
STEP #21: Installing valve body should be done very carefully.
STEP #22: It may be necessary to remove special modulator valve and spring from valve body to install

valve body in the case.
STEP #23: Being very careful, place new valve body into transmission, guiding the Servo Tube, the

Manual Valve Body and the Detent Spring Bracket into place. Sometimes it may be

necessary to tap on Servo Tube to get into hole in case. Also be careful not to damage

gasket. (See Fig. #2 & #3)
STEP #24: Start six bolts in valve body. Be sure Servo Tube, Manual Valve and Detent Spring Bracket

are properly in place. (See Fig. #2)
STEP #25: Tighten six bolts to 8-10 ft./lbs.

STEP #26: Place shift lever guide plate and two bolts into place being sure the Manual Valve is properly

lined up with the shift lever. (See Fig. #1)
STEP #27: Tighten bolts to 8-10 ft./lbs.
STEP #28: Connect Detent Spring to Detent Spring Bracket and Valve Body Bracket with pair of needle

nose pliers. (See Fig. #2)
STEP #29: Install special modulator valve and spring back into valve body. If you did not remove, go on

to STEP #31.
STEP #30: Install solenoid #22280B and modulator gasket #22077-1 using a large pair of pliers and

tighten (10-15 ft./lbs. is adequate). Release time can be adjusted by shimming solenoid

back towards rear of car.
STEP #31: Manually push back of solenoid in and release to see if modulator valve is working freely

and that it springs back when released. Note - Our two wire solenoid must be hooked up as

follows: One wire to 12 volt source, the other wire to ground.
STEP #32: Take old filter and new filter gasket #22076 and install on new valve body. If filter needs

replacing, use a Turbo Action #22006. Be sure old filter is clean.
STEP #33: Install new pan gasket #22072 and reinstall pan.
STEP #34: IMPORTANT! Adjust Front Band:

Back off lock nut with 9/16” box end wrench. Use a 7/32” hex key wrench and turn

clockwise to 10 in./lbs. Be sure lock nut doesn’t turn in while turning hex key wrench. Now

turn hex key wrench counter clockwise four (4) full turns and tighten lock nut being sure

hex key wrench doesn’t turn.
STEP #35: Depending on your preference install a 10-20 AMP momentary switch. Turbo Action offers a

completely sealed micro switch with industrial stretch cord for the steering wheel #00774.

Use a good 12 volt source with #14 gauge wire (See Fig. #4).
STEP #36: Refill transmission with a good brand of type “F” or Dexron Mercon transmission fluid. Add

approximately only three quarts. Warm transmission up and place in all gears, then check to

make sure transmission level is on the add mark. Add oil if necessary to bring to the full

mark. DO NOT OVERFILL!

The Tranz Brake takes some getting use too. This valve body works same as our standard Cheetah Valve
Body if you do not engage momentary switch.

CAUTION: Be sure when car is in low gear that you engage switch only when car is stopped!!!

OPTIONAL:

1. Governor assembly can be removed.

2. Remove vacuum modulator lines.
