3500 or higher TC or it will cause the tranny to over heat and crash? We were told by two highly recommended tranny guys that you shouldn't run over 2500 stall, even with a tranny cooler. Anyone have any REAL experience with this? Or why this would be different then an Fbody?

Are they talking about LT1's?? The only reason they usually use/suggest a 2500-3000 stall is because the power band is a bit lower than LS1's. BTW the vettes use a 4L60E just like every other A4 f-body. They are prolly old school builders.

I can't see why it would make any difference if its a fbody or corvette. His problem is something other than the size of his stall. Most tranny builders will tell you not to use a high stall. Hell, even speed shops have told me my 3800 is way too big. My tranny has not overheated once since I've had my converter, not even close(180 the highest). I do have a large cooler though. I guess some places just havn't caught up with the new technology.

Well I've had 5 different converters now and the current one is by far the biggest (supposed to be a 4200 but feels ALOT bigger, more like a 4800) and I haven't had any problems besides the converters themselves breaking. There's no difference between how the C5 and F-body transmissions function, except that one uses a torque tube and one doesn't. As long as you keep your fluid at the right level and monitor the temp, you'll be OK.
Tell your tranny builder he's full of **** and take your car somewhere else.

Based on your posts elsewhere I'm inclined to think the converter was not installed correctly initially (i.e. should never have left the shop with "vibration") and the rest of your issues are secondary.
Merry Christmas!

The C5 did have tuning. The low rmp misfire was changed and the line pressures was in creased a little, more at WOT that part throttle. Shift points were rasied a bit too. Bascily the same tune that was done on several fbodies with the same TC.

That's not the first 4L60 to bite the bullet. It doesn't matter what car it is in, it's just not a tough tranny stock
