1992 Buick Century Q&A

1992 Buick Century Question: My 92 Buick Century 3.3l has been jerking and dying when brakes are applied??

The first 10-15 mins. it runs great, but then it will stall, jerk, and die when I brake or stop completely. To keep it running I have to slip it into neutral while stopped, and slip it back into drive when I need to take off. It jerks a little when I take off too. The spark plugs and wires are fine, and the coil pack was replaced, so I don't know if the timing is off or what. Please help I need to fix it ASAP! -
Answer 1
It sounds like a torque convertor clutch switch problem. It keeps the torque convertor locked up and feels like it is stays in high gear and not shifting down. -
Answer 2
Very easy fix, Unplug the transmission lockup solenoid which is under the hood & easy to get to. It fixed my 92 Buick Century & now it runs great -
