AUTOMATIC TRANSMISSION (3 A / T) (VEHICLE WITH WU-TWC) 7B-3
GENERAL DESCRIPTION
The automatic transmission consists of the hydraulic torque converter, electronically controlled 3-speed automatic
transmission, countershaft and differential.
The transmission consists of 2 planetary gears, 2 disk clutches, 1 band brake, 1 disk brake and 1 one-way clutch.
Its operation is controlled by selecting a position from 6 positions (P, R, N, D, 2 and L ranges) manually by means
of the selector lever installed on the compartment floor.
In the D or 2 range, the gear ratio is changed for the 1st, 2nd or 3rd speed (D range only) automatically by engine
control module (electronic control).
For the automatic transmission fluid, DEXRON

E, DEXRON-


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, front wheels must be raised so as not to roll them.
