My 93 GT upshifts at 3200rpm no matter how hard or soft I accelerate.
It will stay in 2nd gear until the rpms go up to 3200.
Is there and adjustment I need to make to have if shift right.
Im told its either a TPS adjustment or a cable adjustment.
Any help is appreciated.

First thing to check would be the throttle valve cable, check out this thread, there's a video on how to adjust it.

You can adjust set pressure and TPS voltage. But if they are to factory spec, ajusting them out won't help a thing.

The tps has mor to do with your rngine function, but checkifn it never hurts.

The AOD is set to a certain presure at idle for proper operation. This requires small gage, or block to be made to set the gap.

I believe TCI and maybe even the haynes manual may be able to show you this procedure in pictures and be a whole lot easier than explaing i here.

THough, the truth is that the tranny is no longer building pressure internally at RPMS and holding the shifts out long enough. This usually means rebuild time.
