Manual Transmission/Transaxle: Description and Operation

GENERAL DESCRIPTION





The manual transmission consists of the input shaft, main shaft, countershaft and reverse gear which are installed in the aluminum case. Its gears are of forward five speeds in synchro mesh and reverse one speed in constant mesh system.
The main shaft gears are held by the needle bearings and on them the synchronizer rings and synchronizer sleeve & hubs are assembled.
The gear shift lever case is located at the upper behind the transmission case and has a cam which prevents direct gear shift from the 5th speed gear to the reverse gear.
As the aluminum case is sealed with liquid type gasket, it is necessary to use genuine sealant or its equivalent on its mating surfaces when reassembling it. Also, the case fastening bolts must be tightened to specified torque by means of the torque wrench and tightening over or below the specified torque should be avoided.
The description under Manual Transmission Type 2 covers a part of the TYPE 2 manual transmission and the transfer. The transfer is next to the transmission as well, but their gear boxes are independent and each of them has its own drain and level/filler plugs for the oil change or the level check.
For the repair procedure of the transfer unit, refer to Transfer Case.
