tune(shift problems)
I was wondering if all lt1 autos hit the rev limit before they shift,mine does me shifting it,or leaving it in drive it cuts out and falls on its face about 5,800 then shifts ,and it seems alot worse since I installed my headers.I know its costing me a few tenths,will a tune fix this problem completely?

IMO a tune will be a band aid. If the transmission is hitting rev limiter then its most likely hurt. Same thing happened to me. I threw more horsepower at it and it blew the rear planetary up. Tore it apart and the 2-3 bands were gone along with the 3-4 on the way out. If you plan to throw some power at it, id suggest start looking into a rebuild.

When you say it shifts "firm" are you saying the tranny shifts hard into each gear? I had mine rebuilt and had a shift kit put in and it snaps you back into your seat when it goes into the next gear. I had Bryan at PCM4LESS do my tune. It still shifts into gears after. It doesn't shift at those rpm's you are saying unless I am putting the pedal to the floor.
