Conditions for Setting the DTC

WARNING: This page is about a different car, the 2005 Cadillac STS. However, it is still accessible from the selected car via links, so may be relevant.

Both of the following conditions must occur once during the same trip:

The TCM commands 3rd gear when the output shaft speed is 200 RPM or greater, the engine torque is greater than 20 N.m (15 lb ft), and the resulting gear ratio is 2.16:1-2.27:1 for 2 seconds.
The TCM commands 4th or 5th gear when the engine torque is greater than 12 N.m (9 lb ft) and the resulting gear ratio is 3.33:1-3.50:1 for 2 seconds.
