GENERAL DESCRIPTION
AT0GE–02
The A340E automatic transmission is a 4–speed Electronically Controlled Transmission with an intelligent
control like the A341E automatic transmission used in the LS400. The A340E automatic transmission has
the following features.
When shifting, engine torque is controlled and the clutch hydraulic pressure in the transmission is
electronically controlled 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: For the A340E automatic transmission, use ATF Type T–II or equivalent.
A super flow torque converter clutch is used to improve the transmission efficiency.
The A340E automatic transmission is mainly composed of a torque converter clutch with lock–up clutch,
4–speed planetary gear unit, hydraulic control system and the electronic control system.
To minimize the possibility of incorrect operation of the automatic transmission, a shift lock mechanism has
also been added.
