Automatic Transmission

• 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.
