Download IDENTIFICATION Transmission is identified by identification plate attached to transmission case, located on left side, above oil pan. Vehicle Identification Number (VIN) may also be used in identifying transmission. VIN locations are at top left of instrument panel and driver’s-side door post. VIN is used to ensure correct application of component parts and assemblies. DESCRIPTION & OPERATION Automatic transmission provides 3 forward speeds and reverse. Main internal components are; oil pump, Torque Converter w/Clutch (TCC), reverse clutch, 2nd clutch, 3rd clutch, one-way clutch (sprag type), compound planetary gear set, low brake, governor and valve body. See Fig. 1. Gear shifting is controlled by valve body. Components that regulate shifting schedules are; governor, modulator and kick-down valve. TCC is operated by an electric solenoid. TCC solenoid operation depends on signals provided by the Engine Coolant Temperature (ECT) sensor, brake switch, Throttle Position (TP) sensor, Vehicle Speed Sensor (VSS) and gear position.
