Initial Inspection and Diagnostic Overview

DESCRIPTION
The A14OE transaxle, also called Electronic Controlled Transaxle (ECT), differs from the oil pressure control type transaxle (A14OL) in that it is controlled by a microcomputer. Accordingly, troubleshooting procedures differ also.

Trouble occurring in the ECT can stem from one of three sources: the engine, the ECT electronic control unit or the transaxle itself. Before troubleshooting, determine in which these three sources the problem lies, and begin troubleshooting with the simplest operation, gradually working up in order of difficulty.
