"Check Trans" Indicator Is Flashing

Mechanical/Hydraulic Diagnosis Check Trans Indicator Chart


Perform Preliminary Inspection First!





When the "CHECK TRANS" indicator is flashing, it indicates that a problem related to the transmission, the Powertrain Control Module (PCM), or the vehicle harness has occurred.
The system is now operating in a "BACKUP MODE" where the risk of further damaging the transmission has been reduced. The vehicle may be shifted manually.
If the initial problem is intermittent or seldom, switching the engine OFF/ON might allow normal operation again until the problem reoccurs.
