SERVICE INFORMATION

An Electronic Transmission Repair Process Chart has been developed for service use on 1989-91 Ford Econoline, Escort, F-Series, Probe, Taurus; 1991 Lincoln Continental; Mercury Capri, Sable, Taurus and 1990-91 Ford Bronco vehicles. The addition of electronic controls to automatic transmissions (E40D, AXODE, 4EAT, etc.) adds to the complexity of diagnosis and repair. Avoiding repeat repairs depends on properly identifying all the root causes of the concern.

Use the Electronic Transmission Repair Process Chart shown in Fig 1 , to assist you in developing a routing system for electronically controlled transmission repairs. Using this routing chart will help in determining the "root cause" for the concern and repeat repairs.
