TRANSMISSION UNIT (AUTOMATIC) Once the engine/transmission unit has been removed from the car, the transmission is easily separated from the engine as detailed below.
Removal Remove the torque converter and converter housing, following the relevant steps given under the previous headings. It should be noted that the engine oil must be drained from the power unit during removal.
If required, the converter output gear can be removed from the end ok the crankshaft, together with its thrust washers.
Disconnect the external oil feed pipe from the adaptor on the transmission casing and the connection on the cylinder block . Lever the main oil feed pipe from the oil pump and the transmission case
Remove the bolts securing the radiator to the lefthand engine mounting bracket and detach the radiator assembly.
Remove all the nuts, bolts and spring washers securing the engine to the transmission casing, then lift the engine to separate it from the transmission unit.
Remove the gaskets from the joint faces, and the oil seal from the front main bearing cap.
Installation Installation is basically a reversal of the removal procedure.
Ensure that the joint faces on both the crankcase and transmission housing are clean and free from old gasket material before fitting new gaskets on the transmission casing. Check that the oil feed 0-ring is in good condition and correctly in place at the oil feed pick-up pipe hole on the transmission casing flange.
Lubricate the new oil sealing strip before fitting it in position at the engine front main bearing.
Lower the engine onto the transmission unit and fit and tighten the securing bolts and nuts.
Check that the oil seals on and in the main oil feed pipe are in good condition, and renew as necessary. Refit the oil feed pipe between the oil pump and the transmission case . Also reconnect the external oil feed pipe between the cylinder block and the adaptor on the transmission casing .
If a replacement transmission unit is being fitted, it will be necessary to check the idler gear end-float before finally assembling the converter housing to the unit. The procedure for checking and adjusting the idler gear endfloat is the same as that already described for manual transmission models and back-reference should be made for details.
The transmission input gear is preloaded, by the use of a selective shim pack, but special tools are required to set the preload for individual gears. It is therefore recommended that this operation be left to an Authorised Dealer or Transmission Specialist.
