Torque Converter Clutch Solenoid

My 2002 Bonneville tends to "chug" or "buck" when the transmission is under a load such as traveling up an incline. A guy at work suggested the torque converter clutch solenoid. Is this a common problem? I have never heard of it before but I have never had a 4T65E transmission. I got the stalling problem fixed but want to get the "chugging" fixed so I have a perfect Bonneville for my wife to drive.

Thanks,

Is this a common problem? Thanks,The TC solenoid is not as common as secondary ignition misfire, which includes wires, coils & plugs. Have all these been checked, or replaced. BTW, how many miles?

I agree... TCC solenoid on the 4T65E is not a common problem..

99% of the time a Buck under load is ignition related..
