RE: 98 deville cackling trans

Does this noiserise and fall with RPM of the engine while in a drive gear? or just constant.

Probable cracked flex plate. Find a way to look at the bottom of the torque converter. Usually a cracked flex plate will have rust stains down from the cracked bolt hole holding it to the torque converter. Rather common failure.

Would appreciate a response to the noise. Did you find the cause?
