Re: '94 Deville 4.9l torque conv. clutch prob?
Is the torque converter new? It could be something unrelated too. A bad miss, some sort of EGR problem or catalytic problem could make it jerk and buck too. It seems like it would throw a code if it was a TCC problem. Good luck, let us know if you figure it out.
