Transmission Computer Diagnostics

Virtually every modern-day transmission has some kind of computer controls. Whether it’s as simple as controlling the torque converter clutch application or as complicated as a fully computerized shift and pressure control capable system, they all depend on computer modules. This complex system integrated with engine control units “ECU” makes diagnosing problems with today’s modern transmissions even more complicated and a job for the professional technician.

The first step for any computer control repair is to install a diagnostic scan tool onto the data link connector to retrieve any trouble codes in the computer system. After the code retrieval, the input and output data of the computer can be checked for abnormal parameter readings. The symptom fault can now be classified as electrical, hydraulic or mechanical.
