Automatic Transmission

NOTE:

For the electric components to work properly, a voltage of at least 11.5 V is required.

Transmission Control Module (TCM) is equipped with On Board Diagnostic (OBD).

It is possible that the control module will recognize a malfunction and store a DTC during some tests. Therefore the following work steps must be performed in the mentioned sequence after ending all tests and repairs.

The Transmission Control Module (TCM) receives information from components that affect shifts and forwards this information to solenoid valves, through which slide valves in valve body are controlled.
