    You'll come out cheaper just buying a Performabuilt Stage 2 4L60E. The one I have is good to 700hp and was around $1500.00 which is what you'll pay to get yours rebuilt. I had 2 rebuilt and they never did work right. Shift kits, Raybestos clutch packs and the good stuff. But it was a waste of money because you can buy a better product than the local boy can build. Don't waste your money.

    At 150K miles changing the fluid was not the best of moves. That thick fluid was helping your clutches apply.

    Incorrect. It was hurting it because it shifts great now and im getting better mileage and more power. I added a quart of lucas to it so it would thicken it back up as well.
