DESCRIPTION
GENERAL DESCRIPTION
The A340E is a 4-speed, Electronically Controlled Transmission developed for use with high-perfor-
mance engines. A lock-up mechanism is built into the torque converter clutch.
The A340E automatic transmission is mainly composed of the torque converter clutch, the overdrive
(hereafter called O/D) planetary gear unit, a 3-speed planetary gear unit, a hydraulic control system
and an electronic control system.
