7. Remove front pump seal and discard.

ASSEMBLY

1. Install the front pump seal using Front Pump Seal Replacer 307-014 (T63L-77837-A).

2. Install new intermediate clutch piston inner seal and intermediate clutch piston outer seal on intermediate clutch piston.

3. Note location of the piston bleed hole.

CAUTION: The piston bleed hole must be located at 12 o'clock position (toward top of transmission). If incorrectly installed, transmission may not operate properly.

NOTE: Piston bleed hole is the only round hole in the intermediate clutch piston assembly.

4. Install intermediate clutch piston as follows:
a. Install intermediate clutch piston in Intermediate Clutch Piston Seal Protector 307-339 (T95L-77005-A).

NOTE: Coat intermediate clutch piston outer seal and intermediate clutch piston inner seal and pump body sealing area with petroleum jelly.

5. Install intermediate clutch piston in pump body and push intermediate clutch piston to the bottom of the bore by exerting even pressure.

6. Snap spring retainer assembly into place on pump body.
7. Install the inner and outer pump gerotors in pump body.

The flats have steps that must face the pump body for ease of installing the torque converter.

8. Install reverse clutch cylinder seal and forward clutch cylinder seals.

9. Position pump stator support to pump body and install retaining bolts. Tighten to 20 - 26 Nm (15 - 19 ft. lbs.).
