9. Support cradle at rear with screw jack or equivalent. Partially remove engine cradle crossmember-to-body bolts, lowering cradle at rear enough to facilitate cradle pivoting.
10. Support cradle at front with screw jack or equivalent. Remove engine cradle crossmember-to-body bolts. Lower cradle at front approximately 10 inches to facilitate valve body removal.





11. Remove oil pan bolts (Fig. 161).





12. Remove oil pan (Fig. 162).





13. Remove oil filter (Fig. 163).





14. Remove the valve body-to-transaxle case bolts (Fig. 164).

NOTE: To ease removal of the valve body, turn the manual valve lever fully clockwise to low or first gear.








15. Remove park rod rollers from guide bracket and remove valve body from transaxle (Fig. 165) (Fig. 166). Note position of accumulator and springs upon removal for assembly reference.

CAUTION: The valve body manual shaft pilot may distort and bind the manual valve if the valve body is mishandled or dropped.

DISASSEMBLY

NOTE: If valve body assembly is being reconditioned, the PCM/TCM Quick Learn Procedure must be performed.





1. Remove manual shaft seal (Fig. 167).





2. Remove Transmission Range Sensor retaining screw (Fig. 168).





3. Remove Manual Shaft/Rooster Comb and Transmission Range Sensor (Fig. 169).

1. Install valves and springs as shown in (Fig. 182).





2. Install regulator valve spring retainer (Fig. 183).





3. Install dual retainer plate using Tool 6301 (Fig. 184).





4. Verify that all retainers are installed as shown in (Fig. 185). Retainers should be flush or below valve body surface.





5. Install check balls into position as shown in (Fig. 186). If necessary, secure them with petrolatum or transmission assembly gel for assembly ease.





6. Install thermal valve into transfer plate (Fig. 187).





7. Install separator plate to valve body (Fig. 188).





8. Install the overdrive clutch (#5) check valve to separator plate (Fig. 189)





9. Install oil screen to separator plate (Fig. 190).
