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





11. REMOVE OIL PAN

NOTE: Do not turn the transmission over as this will contaminate the valve body with any foreign matter at 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

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

c. Remove pan by lifting the transmission case.





12. EXAMINE PARTICLES IN PAN
Remove the magnets and use them to collect steel particles. Carefully look at the foreign matter and particles in the pan and on the magnets to anticipate the type of wear you will find in the transmission:

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





13. REMOVE OIL STRAINER AND GASKETS
a. Turn over the transmission.
b. Remove the three bolts holding the oil strainer to the valve body.
c. Remove the oil strainer and two gaskets.





14. REMOVE OIL TUBES
Pry up both tube ends with a large screwdriver and remove the two tubes.

15. REMOVE SOLENOID WIRING





a. Disconnect the three connectors from No.1, No.2 and lock-up solenoids.





b. Turn over transmission, remove the stopper plate from the case.
c. Pull the wiring out of the transmission case.
d. Remove the O-ring from the grommet.

b. Disconnect the throttle cable from the cam and remove the valve body.

17. REMOVE CHECK BALL BODY, ACCUMULATOR SPRINGS, PINS AND PISTONS





a. Remove the check ball body and spring.
b. Remove the two springs from the C(0) accumulator piston.





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





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





e. Applying compressed air to the oil hole, remove the C(0) accumulator piston.
f. Remove the O-rings from each piston.

b. Remove the race and assembled bearing and race.





c. Remove the bearing and race.





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

21. CHECK PISTON STROKE OF OVERDRIVE BRAKE





a. Place SST and a dial indicator onto the overdrive brake piston as shown in the figure.
SST 09350-30020 (09350-06120)





b. Measure the stroke applying and releasing the compressed air (4 - 8 kg/sq.cm, 57 - 114 psi or 392 - 785 kPa) as shown in the figure.

Piston stroke:
7M-GE 1.40-1.70 mm (0.0551 - 0.0669 in.)
7M-GTE 1.75-2.05 mm (0.0689 - 0.0807 in.)

If the values are nonstandard, inspect the discs.
