    Default 98 Pontiac Firebird WOT Shift

    POSTED IN WRONG SUBFORUM DUE TO FAT FINGER.... Needs to be deleted. Sorry!

    So my buddy has a 98 firebird formula. I ran a few scans on it because his trans was unable to shift from 2nd to 3rd at WOT. After looking at the cal, I reduced to timing for shift & took out torque reduction (he's planning on racing at the strip). We were still unable to shift. I checked the rpm shift, then set it to 5700 rpms and adjusted the vss to 77mph (vehicle was reporting 80 at 5700). Still no luck. Finally I adjusted the parameters for using the WOT shift tables, to have a lower and user threshold of 100%. I basically forced the trans to use the partial shift tables even at WOT. It shifted.... Anyone have any ideas on this and why it won't shift using the wot tables? The values were almost identical to the partial throttle shift tables. Anything helps! Thanks!
