Removing






Drive the vehicle onto a ramp and disconnect the battery.

Remove the dipstick from the dipstick tube; remove the bolt securing the dipstick tube to the manifold.
Remove the bolts securing the upper fan cowl to the lower fan cowl. Slacken the bolts securing the cowl bracket to the radiator, to facilitate the removal of the top cowl
Remove and discard the Split pin securing the kick-down cable to the throttle bell-crank. withdraw the clevis pin and washer; slacken the locknut and disconnect the cable
Raise the ramp.
Undo the union nut securing the dipstick tube to the transmission unit sump pan. Remove the dipstick tube; plug the ends to prevent the ingress of dirt. Drain and discard the transmission fluid.
Disconnect the exhaust intermediate pipe from the down-pipe, remove the olive. Remove the exhaust heat shields from the floor pan.
Position the transmission unit lift under the transmission unit, and take the weight. Secure the transmission unit to the lift.
Remove the bolts securing the crash plate to the transmission case studs, undo the nut securing the crash plate to the rear mounting spigot bolt.
Remove the bolts, spacers and washers securing the rear engine mounting to the floor pan. Remove the bolts securing the propeller shaft tunnel spreader plate to the floor pan.
Chock the front wheels.
Using a ramp lack raise the rear wheels. This will enable the propeller shaft to be rotated and the propeller shaft to output flange fixings removed.
Move the propeller shaft clear of the output flange.
Lower the transmission unit lift to the position required for transmission unit removal; DO NOT REMOVE the transmission unit at this stage.

CAUTION: Take care not to damage the water heater valve.

Position the engine support bracket. MS 53A, and locate the hook to the engine rear lifting eye. Turn the adjusting nut to take the weight of the engine (Fig. 26).

Remove the bolt securing the selector cable trunnion to the mounting bracket.
Remove the bolts securing the tie-plate to the engine sump pan and transmission converter housing front cover-plate and remove the cover-plate.
Rotate the engine until a torque converter securing bolt is accessible; knock back the lock tab and remove the bolt. repeat this procedure for the three remaining torque converter securing bolts.
Remove and discard the tab washers.
Remove the bolt and washer securing the breather pipe clip.
Remove the screw securing the oil cooler pipe clamp plate to the sump bracket.
Disconnect the oil cooler and breather pipes from the transmission casing, plug or tape broken connections to prevent the ingress of dirt. Disconnect the speedometer cable from the drive pinion (early models).
For later models fitted with electronic speedometer disconnect 2 pin connector only. Disconnect the cables from the starter motor and solenoid.
Ensure that the transmission unit is secured to the unit lift and that the platform is at the correct angle.
Remove the nuts. bolts and washers securing the torque converter housing to the cylinder block, withdraw the starter motor and spacer. Withdraw the transmission unit lift rearwards and lower.
Remove the torque converter from the input shaft.
Remove the bolts and washers securing the torque converter housing to the transmission case.

Refitting

Refit the torque converter housing to the trans- mission case and tighten the securing bolts to the correct torque.
