Installation

Transmission and converter must be installed as an assembly. The drive plate will not support a load and no weight from transmission should be allowed to rest on plate during installation.
1. Using tool No. C-3756 or equivalent, rotate pump rotors until two small holes in handle are vertical.
2. Carefully slide converter assembly over input shaft and reaction shaft, ensuring converter hub slots are vertical and fully engage pump inner rotor lugs.
3. Test for full engagement by measuring distance from transmission case bellhousing front surface to ends of three drive plate attaching bosses of torque converter. Distance should be at least .6 inch when torque converter is pushed all the way into transmission.
4. Inspect converter drive plate and adapter for cracking or distortion and replace as necessary. Torque drive plate to crankshaft bolts to 94-101 ft. lbs.
5. Ensure bushing has been inserted into crankshaft rear end hole and apply suitable grease to bushing bore.
6. Place transmission and converter assembly on suitable jack, position under vehicle, and raise or tilt as necessary to align transmission with engine.
7. Line up dowel hole of transmission assembly with dowel bushing of engine cylinder block and adjust to ensure converter hub fits in hole of crankshaft, then install and torque converter housing bolts to 31-40 ft. lbs.
8. Install rear engine support brackets to body, lower transmission, and install extension housing mount to rear insulator.
9. Install oil filler tube and speedometer cable, then connect throttle rod A to transmission throttle lever.
10. Connect control rod to manual control lever.
11. Carefully guide sleeve yoke into extension housing and onto output shaft splines, align marks made during removal, and connect propeller shaft.
12. Install converter to drive plate bolts and torque to 33-38 ft. lbs.
13. Install starter, then tighten cooler lines to transmission fittings.
14. Adjust control rod and throttle linkage, then fill transmission to specifications using Mitsubishi Plus ATF.
