"Check Trans" Check

"CHECK TRANS" Indicator Chart:

NOTE: Perform preliminary inspection first!

When the "CHECK TRANS" indicator is flashing, it indicates that a problem related to the transmission, the Transmission Control Module (TCM), 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 OFF/ON the engine might allow normal operation again until the problem re-occurs.
