synthetic oil/trans fluid?
Do any of the hard core Bonneville drivers use this stuff? Good results or bad news?

Yes, I use synthetic oil. It was my dad's car before i got it and he always used synthetic oil. my car has almost 130,000 and the transmition seems to be great no problems. The only thing that i don't like is the cost of the stuff. Plus, once u use it, you really can't go back. I recomend it.

It is strongly reccommended by jr's3800, one of our local tranny gurus, that you do NOT use Synthetic trans fluid in a 4T60 or 4T65! It's too slippery, and after you realize you have slippage problems, it's too late. You can't just flush it out and replace it. Run Synth in the engine, but not the tranny. I'm switching over to a synthetic blend for the first time at my next pit stop.

As the Bird man said.

Haven't had a proplem!!!
I put synthetic in about 30,000 miles ago and haven't had any type of slippage problems to date. Now I probably don't drive as hard as some of you guys but haven't had any problems.
