SEPARATE BASIC SUBASSEMBLY




1. REMOVE WIRE HARNESS CLAMP AND THROTTLE CABLE CLAMP




2. REMOVE CONTROL SHAFT LEVER




3. REMOVE NEUTRAL START SWITCH

b. Remove the speed sensor.




7. REMOVE TRANSMISSION HOUSING
a. Remove the six bolts.
b. Remove the transmission housing.




8. REMOVE EXTENSION HOUSING
a. Remove the six bolts.
b. Remove the extension housing and gasket.




9. INSPECT EXTENSION HOUSING BUSHING
Using a cylinder gauge, measure the inside diameter of the extension housing bushing.

Maximum inside diameter: 40.09 mm (1.5783 in.)

If the inside diameter is greater the maximum, replace the extension housing.




10. REMOVE SPEEDOMETER DRIVE GEAR
a. Using snap ring pliers, remove the snap ring.
b. Remove the speedometer drive gear and ball.




11. REMOVE SENSOR ROTOR
a. Remove the sensor rotor and key.
b. Using snap ring pliers, remove the snap ring.

12. REMOVE OIL PAN

CAUTION: Do not turn over the transmission as this will contaminate the valve body with the foreign material in the bottom of the pan.

a. Remove the nineteen bolts.



b. Insert the blade of SST between the transmission case and oil pan, cut off applied sealer.
SST 09032-00100

CAUTION: Be careful not to damage the oil pan flange.

c. Remove pan by lifting the transmission case.




13. EXAMINE PARTICLES IN PAN
Remove the magnet and use it to collect any steel chips.
Look carefully at the chips and particles in the pan and on the magnet to anticipate what type of wear you will find in the transmission:

Steel (magnetic)................. bearing, gear and clutch plate wear
Brass (non-magnetic) ............ bushing wear




14. TURN OVER TRANSMISSION AND REMOVE OIL STRAINER
a. Remove three bolts holding the oil strainer to the valve body.
b. Remove the oil strainer and two gaskets.




15. REMOVE THE TWO OIL TUBES
Pry up both tube ends with a large screwdriver and remove the tubes.

16. REMOVE SOLENOID WIRING



a. Disconnect the connectors from the No.1, No.2 and No.3 solenoids.




b. Turn over transmission, remove the stopper plate from the case.
c. Pull the wiring out of the transmission case.

17. REMOVE VALVE BODY



a. Remove the seventeen bolts.




b. Disconnect the throttle cable from the cam.




18. REMOVE CHECK BALL BODY, SPRINGS AND PINS
a. Remove the check ball body and spring.
b. Remove the four springs and two pins from accumulator pistons.

19. REMOVE ACCUMULATOR PISTONS AND SPRINGS



a. Applying compressed air to the oil hole, remove the B(2) and C(2) accumulator pistons and two springs.




b. Applying compressed air to the oil hole, remove the B(0) accumulator piston and spring.




c. Applying compressed air to the oil hole, remove the C(0) accumulator piston.




20. TURN OVER TRANSMISSION AND REMOVE THROTTLE CABLE
21. STAND UP TRANSMISSION AND REMOVE OIL PUMP



a. Remove seven bolts holding the oil pump to the transmission case.




b. Using SST, remove the oil pump.
SST 09350-30020 (09350-07020)




22. REMOVE RACE FROM OIL PUMP
23. REMOVE OVERDRIVE PLANETARY GEAR AND OVERDRIVE DIRECT CLUTCH



a. Remove the overdrive planetary gear and overdrive direct clutch from the transmission case.




b. Remove the race.

24. REMOVE OVERDRIVE PLANETARY RING GEAR



a. Remove the bearing and race.




b. Remove the overdrive planetary ring gear from the transmission case.

25. REMOVE FLANGES, PLATES AND DISCS



a. Remove the snap ring.




b. Remove the flanges, plates and discs.

7M-GE: Two flanges, three plates and four discs
7M-GTE: Two flanges, four plates and five discs

26. CHECK PISTON STROKE OF SECOND COAST BRAKE



a. Place a mark on the second coast brake piston rod as shown in the figure.




b. Using SST, measure the stroke applying the compressed air (4 - 8 kg/sq.cm, 57 - 114 psi or 392 - 785 kPa) as shown in the figure.
SST 09240-00020

Piston stroke: 1.5 - 3.0 mm (0.059 - 0.118 in.)

If the values are nonstandard, replace piston rod and check piston stroke. If piston stroke is nonstandard, replace brake band.

NOTE: There are two piston rods.

Rod length:
71.4 mm (2.811 in.)
72.9 mm (2.870 in.)




27. REMOVE SECOND COAST BRAKE PISTON
a. Using SST, remove the snap ring.

b. Applying compressed air to the oil hole, remove the second coast brake cover and second coast brake piston assembly.




28. DISASSEMBLE SECOND COAST BRAKE PISTON
a. Remove the E-ring.
b. Remove the piston, spring and retainer from the piston rod.
c. Remove the oil seal ring from the piston.

29. REMOVE OVERDRIVE SUPPORT ASSEMBLY
