Fail Safe Operation

If a major system failure occurs which could affect safety or damage the transmission under normal vehicle operation, the diagnostic system detects the fault and overrides the Powertrain Control Module (PCM). The "CHECK ENGINE" light comes on and the "CHECK TRANS" light flashes to alert the driver, and the transmission must be manually shifted as follows:

Shifts are firmer to prevent clutch slip and consequent wear. The fault should be corrected as soon as possible.
