Automatic Transmission System

The A34OE automatic transmission is a 4-speed Electronically Controlled Transmission with an intelligent control like the A341E automatic transmission used in the SC4OO. The A34OE 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 A34OE automatic transmission, use ATF Type T- II or equivalent.

- A super flow torque converter clutch is used to improve the transmission efficiency. The A34OE 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.
