DESCRIPTION
The A140L and. A140E automatic transaxle described in this AT section is a lock±up four±speed automat-
ic transaxle developed exclusively for use± with a transversely±mounted engine.
The A140E is called an ECT (Electronic Controlled Transaxle). Based on the A140L, the hydraulic control
system has been changed, and the shift and lock±up timing are controlled by micro computer.
The construction and operation of the A140L, will first be explained. Then the difference between the
A140E
and the A140L, and the features of the ECT, will also be explained.
