tune question i just swapped my rear end from a 273 to a 323 and was wondering if not getting a tune could cause the transmission to feel like its slipping. i know that the computer has to be retuned for the speedometer to be corrected, but now it is slipping above 4000 rpms in every gear and im wondering if im having a mechanical issue or if it could be a possible tuning problem. thank you.

It could be. Not tuning it can cause shift problems in some cases.
Someone else just had the same issue:

If you just noticed it after you changed the rear and it was working fine before, then that's almost certainly the problem.
Transmissions usually slowly start slipping. It's a gradual process. So it was mechanical you would probably have noticed it getting worse over time, not starting all at one point.
