INSTALLATION
1. Check torque converter hub and hub drive flats for sharp edges burrs, scratches, or nicks. Polish the hub and
flats with 320/400 grit paper and crocus cloth if necessary. The hub must be smooth to avoid damaging pump
seal at installation.
2. If a replacement transmission is being installed, transfer any components necessary, such as the manual shift
lever and shift cable bracket, from the original transmission onto the replacement transmission.
3. Lubricate oil pump seal lip with transmission fluid.
4. Place torque converter (1) in position in transmis-
sion (2).
CAUTION: Do not damage oil pump seal or con-
verter hub while inserting torque converter into
the front of the transmission.
5. Align torque converter to oil pump seal opening.
6. Insert torque converter hub into oil pump.
7. While pushing torque converter inward, rotate con-
verter until converter is fully seated in the oil pump
gears.
8. Check converter seating with a scale and straight-
edge (A). Surface of converter lugs should be at
least 19 mm (3/4 in.) to rear of straightedge when

T
High Temp
Grease to the torque converter hub pocket in the
rear pocket of the engine’s crankshaft.

16. Install remaining torque converter housing to engine bolts (2). Tighten to 39 N·m (29 ft.lbs.).
17. Install rear transmission crossmember (1). Tighten
crossmember to frame bolts to 68 N·m (50 ft.lbs.).
18. Install rear support (3) to transmission. Tighten
bolts to 47 N·m (35 ft.lbs.).
19. Lower transmission onto crossmember and install
