# Service bulletin G\-193017

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

13120C \- SERVICE UPDATE \(REVISED EXPIRATION DATE\). THIS BULLETIN PROVIDES A SERVICE PROCEDURE TO REPROGRAM THE TRANSMISSION CONTROL MODULE \(TCM\) ON CERTAIN VEHICLES, EQUIPPED WITH 6\-SPEED AUTOMATIC TRANSMISSION. THE TORQUE CONVERTER CLUTCH SOLENOID IN THE TECHM CAN STICK DUE TO DEBRIS IN THE TRANSMISSION. WHEN THE VEHICLE IS AT THE END OF A COAST\-DOWN, AS THE VEHICLE IS COMING TO A STOP, A STUCK SOLENOID WILL FAIL TO RELEASE THE TORQUE CONVERTER CLUTCH. THIS KEEPS THE ENGINE DIRECTLY CONNECTED TO THE DRIVEN WHEELS. AS THE VEHICLE STOPS, THE ENGINE SPEED WILL BE PULLED DOWN BELOW NORMAL IDLE SPEED AND THE ENGINE MAY STALL. THE VEHICLE CAN BE IMMEDIATELY RESTARTED AND DRIVEN. THE REPROGRAMMING WILL INSTALL A REVISED CALIBRATION TO CORRECT THIS CONDITION.
