I meant...if I needed a tranny rebuild done. Sorry to get off toipic.

So.. just an update here:

I passed on everything that came out of this discussion to my rebuilder. We're probably going to do this right after NEBF (Mid April). Timing is best for both of us.

Last thing on my mind I wanted to ask Matt and Bill and anyone else who rebuilt the 4T60-E-HD for performance: Did you change the stall at all? Originally I was thinking I'm just going to leave it alone, but I decided I'd better check while I'm still in the planning stage.

While the transmission is out, I'll rebuild my supercharger and take care of some other house cleaning projects.

Do NOT mess with the stall. You'll cook your trans. Higher trans temps are the most obvious side-effect of a higher stall.

The only car on this Forum that I know PERSONALLY to have raised the stall regrets it, and is changing it back.

Thanks. That answers that. I'm looking to roast racing tires, not transmissions.

When Mike Senia raced his FWD GM car in NHRA Stock Eliminator, he just went 200 RPM'* higher than the OEM stall speed, but had the same OEM RPM for lock-up.
