I have been having issues with the current tune on my 2002 Avalanche supplying too much transmission pressure with the new tranny that has an HD clutch pack and HD pump. It causes fluid to leak past the slip differential seal under heavy load. So my thought process was to load the tranny parameters from my saved 2008 stock profile and leave the rest that same. Funny thing is there is a whole page of options on the old tune that is not on the present one I scanned tonight. Why is that? I have uploaded a screen shot of the old options page and the latest tune.
