Re: Please Help....Tranny Problem... (~Sweet Cheeks~)
In your PCM program there is a page called transmission calibration, within that page there is a chart called (normal mode shift mph) , (performance mode shift mph) & the same for rpm shifts. It sounds like this has changed for some unknown reason, if its still under warrenty take it to a dealer, if not someone with a LS1Edit can look a those #s, see if they are correct & if not, change them to the proper #s to solve your problem. I had that same problem because I changed gears, 2.73 to 3.42, & when you do that you have to change those #s to avoid hitting the rev limiter. Hope this helps. :cheers:

I doubt that you are hitting the rev limiter with an A4...Go to the dealer and have them perform the following reprogram TSB...Common problem on the 2001 A4 :yesnod:
--------------------------------------------------------------------------------
Lack of Power Following a Wide Open Throttle 4-2 or 3-2 Downshift and Subsequent 2-3 Upshift (Reprogram PCM) #02-06-04-001 - (01/08/2002)
Lack of Power Following a Wide Open Throttle 4-2 or 3-2 Downshift and Subsequent 2-3 Upshift (Reprogram PCM)
2001 Chevrolet Corvette With 5.7L Engine (VIN G - RPO LS1)
Condition
Some customers may comment that the engine lacks power following a wide open throttle downshift, either 3-2 or 4-2, followed by a wide open throttle 2-3 upshift.
Correction
A new service calibration is available for this condition. This calibration is available from Techline starting September 2001, on the TIS 2000 version TIS 10/2001 data update or later. Reprogram the PCM with the new calibration.
