DIAGNOSIS

BASIC TROUBLESHOOTING

AW30-40LE transmission, called Electronic Controlled Transmission (ECT), differs from oil pressure control type
transmissions in that it is controlled by a microcomputer. Accordingly, its troubleshooting procedure differs also.
Before troubleshooting an ECT, first determine whether the problem is electrical or mechanical. To do this, just refer to
the basic troubleshooting flowchart provided below. If the cause is already known, using the basic troubleshooting
chart below along with the general troubleshooting chart on the following page should speed the procedure.
