1994 Cutlass Ciera Stalls When Stopping
Day two: I have just finished driving the vehicle for over two hour at speeds over 60 mph. I was attemping to run the gas that I believe is bad out of the vehicle. I made a stop and as I slowed down the vehicle began to shutter then cut off. I did not get an opportunity to drain the tank of the bad gas and I did put more gas in the vehicle. Please advise. Thanks.
Suggested Repair
Replace the torque converter clutch (TCC) solenoid rather than rebuilding the transmission. The part is roughly $40-$50 and the job about $100-$150 with labor; a dealer part may cost more, and a transmission shop may overcharge. The stall after highway speeds, when slowing or shifting into drive, matches a TCC that engages above about 40-45 mph and fails to release. If it also stalls at low city speeds without converter lockup, have the neutral safety switch checked. Bad gas was considered unlikely.
Conversation Summary
A 1994 Cutlass Ciera with a 4-cylinder engine and about 139,000 miles shuddered and stalled when stopping, then died again when shifted into drive, though it would stay running if revved in neutral first. The owner suspected bad gas and noted a slight transmission leak and slow 1-2 shifts. After highway driving above 60 mph, it still shuddered and shut off while slowing. Experts ruled out bad fuel and identified a classic TCC solenoid failure: the converter locks above about 40-45 mph and stalls the engine if it does not release. They advised replacing the solenoid for roughly $100-$150 instead of a transmission rebuild often costing over $1000.
