car started in 3rd at wot?
autotapped my run up at island tonight...i stalled the car to 1450rpms and then hit it and the tranny upshifted strait to 3rd and was in 4th at wot by 28mph according to autotap any clue as to why? It seems like the trannys been having a hard time deciding which gear to go to since i put in the cam/heads...ive had all missfire codes deleted i believe so im really not sure what to think...the car was only dyno tuned w/ no street tune...my tuners gonna make it right but I'd like to have a heads up if anyone knows whats up with it.
Thanks

I have 373's, but that was when the problem started. Just got the tranny redone yesterday and replaced my tcs4200 with a pt4000 so far so good but I havent been to the track yet. Now that I think about it the first time it broke it wouldnt go to 1st from a stop or anything. You may can clean the valvebody out and hope and pray it will fix it. goodluck
