NOTE:
If the transmission fluid pan gasket is not damaged, it may be reused.
CAUTION:
If installing a new filter and grommet remains in the main control bore, carefully use a small screwdriver to remove the grommet. Use care not to damage the main control bore.
NOTE:
If transmission is being repaired for a contamination-related failure, use a new filter and seal. The filter may be reused if no excessive contamination is present.
CAUTION:
Do not pull on the molded lead frame. This may cause damage to the connector ends. Carefully pry up on the locking tabs to disconnect the solenoids. Disconnect the molded lead frame from the solenoids.
NOTE:
Use a shop cloth to protect the transmission case surface.
CAUTION:
Use care not to damage the manual control lever shaft bore. If the bore is damaged, the new seal may leak.
NOTE:
If tool is not available, extreme care must be taken. Spring pressure will force overdrive servo piston assembly out of case. Case bore damage may result from trying to pry on internal retaining ring.
NOTE:
These bolts have been coated with a sealant. High break torque may be required to remove these bolts.
CAUTION:
Extreme care must be taken during transmission connector removal. Do not use a hammer on the connector body.
NOTE:
These bolts have been coated with sealant. High break torque may be required to remove the bolts.
CAUTION:
Remove the assembly carefully to prevent damage to the overdrive band friction material by the reverse clutch drive lugs.
