Fault symptoms

CHECK GEARBOX warning lamp is on.

TCM in Limp-Home mode.

Conditions

In connection with downshifting, the input speed indicates a speed higher than:

225 km/h for 3rd gear.

132 km/h for 2nd gear.

76 km/h for 1st gear.

Diagnostic help

The symptoms indicate primarily a mechanical fault and it is improbable that it can be caused by a fault in the control system. Wear in the transmission may be the cause of abrupt shifting and an inoperative Lock-up function.
