DESCRIPTION
GENERAL DESCRIPTION
The A340E automatic transmission is a 4-Speed Electronically Controlled Transmission with an intelli-
gent control. The A340E automatic transmission have the following features.

When shifting, the clutch hydraulic pressure in the transmission is controlled by the ECM to reduce
transmission shift shock.to reduce transmission shift shock.

A new type of ATF (ATF Type T-II) is used which provides improved shifting characteristics and
prevents deterioration in the ATF over time.
HINT: The A340E automatic transmission use ATF Type T-II or equivalent.
A super flow torque converter clutch is used to improve transmission efficiency.
The A340E automatic transmission is mainly composed of a torque converter clutch with lock-up
clutch, a 4-speed planetary gear unit, a hydraulic control system and an electronic control system.
To minimize the possibility of incorrect operation of the automatic transmission, a shift lock mechanism
has also been added.
