If you have a 7 S/A you need to install a set of grounding wires. It was the best thing I have done to my car since I bought it. Shifts are crisp and quick and the torque converter does not seem to be sporatic about locking up. There seems to be some improvement in throttle response as well. Very Happy

 

I had them on my 5AT. Haven't put them on my 6MT yet. Black Betty does a great job with his wires. I too noticed a difference.
