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.

3. HYDRAULIC CONTROL SYSTEM
The hydraulic control system is composed of the oil pump, the valve body, the solenoid valves, the accu-
mulators, the clutches and brakes, as well as the fluid passages which connect all of these components.
Based on the hydraulic pressure created by the oil pump, the hydraulic control system governs the hy-
draulic pressure acting on the torque converter clutch, clutches and brakes in accordance with the ve-
hicle driving conditions.
There are 5 solenoid valves on the valve body.
The No.1 and No.2 solenoid valves are turned on and off by signals from the ECM to control the shift
valves, and change the gear shift position.
The No.3 solenoid valve is operated by signals from the ECM to engage or disengage the lock-up
clutch of the torque converter clutch.
The No.4 solenoid valve is operated by signals from the ECM to control the engagement speed and
reduce gear shift shock.
The No.5 solenoid valve is operated by signals from the ECM to regulate the line pressure to throttle
pressure.
