Transmission General Description

This newly developed automatic transmission is a light and compact transmission for FF type small vehicles and provides smooth operation, swift driving, and improved fuel consumption. Its electronically-controlled shift point and shift oil pressure have resulted in delicate gear change control for various driving factors such as throttle position and vehicle speed. Thus, smooth driving at all speeds has been realised.

A symmetrical three-element, single-stage, two-phase torque converter is employed. The transmission consists of 2 single planetary gears, 3 sets of disc clutches, 1 set of disc brakes, 1 set of band brakes, 1 set of one-way clutches, etc.

The number of planetary gears, one-way clutches, and disc brakes is 1 set fewer than the conventional transmission, which improves efficiency.

The transmission may be operated in any of the following gear ranges:

PARK (P): This position locks the rear wheels and prevents the vehicle from rolling either forward or backward. PARK is the best position to use when starting the vehicle. Because the transmission utilises a selector lock control system, it is necessary to fully depress the brake pedal before shifting out of PARK. For safety reasons, use the parking brake in addition to the PARK position.

REVERSE (R): This position allows the vehicle to be operated in a rearward direction.

NEUTRAL (N): This position allows the engine to be started and operated while driving the vehicle. If necessary, you may select this position in order to restart the engine with the vehicle moving. This position should also be used when towing the vehicle.

DRIVE (D): Drive range should be used for all normal driving conditions for maximum efficiency and fuel economy. Drive range allows the transmission to operate in each of the 4 forward gear ratios. Downshifts to a lower gear, or higher gear ratio, are available for safe overtaking depressing the accelerator or by manually selecting a lower gear.
