All transmissions
NOTE:
Coat the reverse clutch piston seals with petroleum jelly.
WARNING:
Do not over compress the return spring or damage to the spring will occur.

Make sure the dimple on the parking guide support plate is facing inward.
Slip yoke transmissions
All transmissions
Diesel engines
CAUTION:
Do not apply air pressure to move the low/reverse piston without first installing the friction plates and the snap ring, or damage to the snap ring will occur.
CAUTION:
Do not apply air pressure to move the low/reverse piston without first installing the friction plates and the snap ring, or damage to the snap ring will occur.
All engines
NOTE:
Alignment pins are used in case holes located at the 5 o'clock and 11 o'clock positions.
NOTE:
Pump-to-case alignment pins are used in case holes located at the 11 o'clock and 5 o'clock positions.
NOTE:
Prior to installing the fluid filter, make sure that the old seal is not stuck in the case.
NOTE:
Reuse the fluid pan gasket unless it is damaged.
CAUTION:
Do not damage the fluid pump gear O-ring seal when installing the torque converter.
CAUTION:
Make sure the converter hub is fully engaged in the front pump support and gear and rotates freely. Do not damage the hub seal.
CAUTION:
If the torque converter slides out, the hub seal may be damaged.
CAUTION:
Use care when installing the torque converter to avoid damage to the front pump stator support seal.
NOTE:
Check the converter crankshaft pilot for nicks or damaged surfaces that can cause interference when installing the transmission to the engine. Check the converter impeller hub for nicks or sharp edges that can damage the pump seal.
