TRANSMISSION, TORQUE CONVERTER, AND DRIVE PLATE INSTALLATION
The transmission and torque converter must be installed as an assembly; otherwise, the torque converter drive plate, pump bushing, and oil seal will be damaged. The drive plate will not support a load; therefore, none of the weight of transmission should be allowed to rest on the plate during installation.
(1) Rotate pump rotors with Tool C-3756 (A�904) or Tool C-3881 (A-727) until the two small holes in handle are vertical (Fig. 52).
(2) Carefully slide torque converter assembly over input shaft and reaction shaft.
Make sure torque converter hub slots are also vertical and fully engage pump inner rotor lugs. Test for full engagement by placing a straightedge on face of the case (Fig. 53). The surface of torque converter front cover lug should be at least 1/2 inch to rear of straightedge when converter is pushed all the way into transmission.
(3) Attach a small "C" clamp to edge of torque converter housing to hold converter in place during transmission installation.
(4) Inspect torque converter drive plate for distortion or cracks and replace if necessary. Torque the drive plate to crankshaft bolts to 55 ft. lbs. (75 N.m). When drive plate replacement has been necessary, make sure both transmission dowel pins are in engine block and they are protruding far enough to hold transmission in alignment. (5) Coat converter hub hole in crankshaft with Multipurpose grease. Place transmission and converter assembly on a service jack and position assembly under vehicle for installation. Raise or tilt as necessary until transmission is aligned with engine.
(6) Rotate torque converter so mark on torque converter (made during removal) will align with mark on drive plate. The offset holes in plate are located next Fig. 53-Measuring Torque Converter for Full Engagement in Transmission to 1/8 inch hole in the inner circle of plate. Carefully work transmission assembly forward over engine block dowels with torque converter hub entering the crankshaft opening.
(7) After transmission is in position, install converter housing bolts and tighten to 30 ft. lbs. (41 N.m). If so equipped, reinstall vibration damper weight on rear of extension housing.
(8) Install crossmember to frame and lower transmission to install mount on extension to the crossmember. Tighten bolts as noted (Fig. 55).
(9) The engine support fixture (Fig. 1), may now be removed.
(10) Install oil filler tube and speedometer cable.
(11) Connect throttle rod to transmission lever.
(12) Connect gearshift rod and torque shaft assembly to transmission lever and frame
NOTE: When it is necessary to disassemble linkage rods from levers which use plastic grommets as retainers, the grommets should be replaced with new grommets. Use a prying tool to force rod from grommet in lever, then cut away old grommet. Use pliers to snap new grommet into lever and rod into grommet.
(13) Place wire connector on the combination back-up lamp and neutral/park starter switch.
(14) Carefully guide sliding yoke into extension housing and on the output shaft splines. Align marks made at removal then connect propeller shaft to rear axle pinion shaft yoke.
(15) Rotate engine clockwise with socket wrench on vibration dampener bolt, as needed to install torque converter to drive plate bolts, matching marks. made at removal. Tighten to 270 in. lbs. (31 N.m).
(16) Install torque converter access cover.
(17) Install starter motor and cooler line bracket.
(18) Tighten cooler lines to transmission fittings.
(19) Install engine to transmission struts, if so equipped. Tighten bolts holding strut to transmission before strut to engine bolts.
(20) Replace exhaust system, if it was disturbed, for clearance.
(21) Adjust shift and throttle linkage.
(22) Refill transmission with "DEXRON II" type automatic transmission fluid.
