Well the last time the tranny in my '98 Camaro Z28 started doing this it lasted for a couple of weeks and then I lost 3rd and 4th gear. I had it rebuilt and it was working great for the past 11k miles and 50+ 1/4 mile passes. All good things must come to an end though. A few weeks ago it started bumping the rev limiter on the 2-3 shift at WOT. It's been getting worse over the past few weeks. It used to do the 2-3 WOT shift fine when the car had just gotten up to operating temperature and then after driving for a 1/2 hour or so it would bump the rev limiter on the 2-3 shift at WOT for the rest of the drive. Now it bumps the rev limiter all of the time on the 2-3 shift at WOT. Partial throttle 2-3 shifts are fine. I took it back to the tranny shop and they said it looked like a computer issue to them. So I tried what joecar recommended in this thread http://forum.efilive.com/showthread....&highlight=2-3 but I still hit the limiter. Could someone please look at the tune and log from one of my runs and let me know if I'm doing something wrong? The tune has the upshift rpm's set to 5000 since the WOT MPH adjustment method didn't seem to work for me. Thanks!
