TA19 and TA22 Transmissions Power Train Electronic Control System Caterpillar

Use the instrument cluster or use the Caterpillar Electronic Technician (Cat ET) in order to determine the diagnostic codes for the Transmission ECM. After determining the diagnostic codes, refer to the corresponding test procedure for more information. Perform the procedure that corresponds with the correct diagnostic code. The following table is a list of possible diagnostic codes for the Transmission ECM.
