Without Overdrive
GENERAL DESCRIPTION
The automatic transmission is composed of a full automatic 3-speed mechanism with a 4-element hydraulic torque converter including Torque Converter Clutch (TCC). Main components of the transmission inside are; oil pump, reverse clutch, 2nd clutch, 3rd clutch, one-way clutch, planetary gear, low brake, governor, parking pawl and valve body.
The gear shift is controlled by the governor (vehicle speed), vacuum modulator (engine intake vacuum) and kick-down valve (accelerator pedal), and the TCC operates depending on such factors as the coolant temperature, brake switch, throttle valve opening, vehicle speed and gear position.
The automatic transmission in the 2WD model is identical in structure and operation with the one in the 4WD model except for the following two points.
- Instead of adapter case, extension case with [1][2]speedometer driven gear is installed.
- Speedometer drive gear is installed on output shaft of planetary gear carrier.
For the automatic transmission fluid, DEXRON-III or its equivalent must be used. Lubrication in the automatic transmission is provided by the oil pump which is operated by the engine revolution. Therefore, the engine should not be stopped even during coasting to obtain proper lubrication. When it becomes necessary to be towed, set the transfer to "NEUTRAL" so as to maintain lubrication in the transmission. Follow the OWNER'S MANUAL for towing procedures in detail.
To prevent transmission parts including torque converter from being over-revolved, it is recommended not to shift down from D to 2 beyond 110 km/h or 68 mile/h and from 2 to L beyond 68 km/h or 42 mile/h.
