INSTALLATION




1. Check torque converter hub inner and outer diameters and hub drive notches for sharp edges burrs, scratches, or nicks. Polish the hub and notches with 320/400 grit paper and crocus cloth if necessary. The hub must be smooth to avoid damaging pump seal at installation.
2. Lubricate pocket in the rear oil pump seal lip with transmission fluid.
3. Lubricate converter pilot hub of the crankshaft with a light coating of Mopar(R) High Temp Grease.
4. Align and install converter in oil pump.
5. Carefully insert converter in oil pump. Then rotate converter back and forth until fully seated in pump gears.
6. Check converter seating with steel scale (1) and straightedge (2). Surface of converter lugs should be 19mm (0.75 in.) to rear of straightedge when converter is fully seated.
7. Temporarily secure converter with C-clamp.




8. For vehicles equipped with a diesel engine;
a. Position transmission on jack and secure it with chains.
b. Check condition of converter driveplate. Replace the plate if cracked, distorted or damaged. Also be sure transmission dowel pins are seated in engine block and protrude far enough to hold transmission in alignment.
c. Raise transmission and align converter with drive plate and converter housing with engine block.
d. Move transmission forward. Then raise, lower or tilt transmission to align converter housing with engine block dowels.
e. Carefully work transmission forward and over engine block dowels until converter hub is seated in crankshaft.
f. Install bolts (5) attaching transmission (3) to engine adapter (2).




9. For vehicles equipped with a gas engine;
a. Position transmission on jack and secure it with chains.
b. Check condition of converter driveplate. Replace the plate if cracked, distorted or damaged. Also be sure transmission dowel pins are seated in engine block and protrude far enough to hold transmission in alignment.
c. Raise transmission and align converter with drive plate and converter housing with engine block.
d. Move transmission forward. Then raise, lower or tilt transmission to align converter housing with engine block dowels.
e. Carefully work transmission forward and over engine block dowels until converter hub is seated in crankshaft.
f. Install bolts (1) attaching transmission (3) to engine (2).




10. Install rear support.
11. Install the rear transmission crossmember.
12. Lower transmission onto crossmember and install bolts attaching transmission mount to crossmember.
13. Remove engine support fixture.

16. Connect gearshift cable (1) and throttle cable (gas engines only) to transmission.




17. For vehicles equipped with a diesel engine, position the transmission throttle valve actuator (TTVA) (1) over the throttle valve shaft (3).
18. Align the D-shaped opening in the bottom of the TTVA to the throttle valve shaft and install the TTVA onto the shaft.
19. Install the wiring connector (2) to the TTVA (1).




20. Rotate the TTVA (1) to the transmission case and install the bolts (2) to hold the TTVA to the transmission.
21. Tighten the bolts to 8.5 Nm (75 in.lbs.).
22. Initialize the TTVA.




23. Connect cooler lines (6, 7) to transmission (5), diesel engine.




24. Connect cooler lines (4, 5) to transmission (3), gas engine.




25. Connect wires to the transmission range sensor and transmission solenoid connector. Be sure the transmission harnesses are properly routed.
