^ agreed, I would still get an aftermarket tach on there to confirm rpms. If the tach is reading right...dont expect that tranny to last all that much longer especially if you are getting on the car in that range frequently

That doesn't seem right to me. There are plenty of F/I guys around town that don't have this problem. Just because you can rev to 7100 and the trans shifts fine doesn't mean it actually isn't shifting at 7100. IIRC, you're peak power is at like 6100 rpm. Meaning your car probably feels good up to around that point.

Only time will tell I suppose. Stock 4r70w don't like seeing 6000+ rpm. So I would definitely try and get an aftermarket tach hooked up to confirm that there is actually a difference in rpms. If the tack is reading right you're going to be getting a new trans much sooner then you're wanting.

Oh trust me i honestly do not beat on the car, and i really dont floor it often. And i know the tranny wont last long in that rpm's i lowered the shift point to 6100 so i will see how it goes.

And wanna b i know it doesnt like that high of rpm's. And i am scared of blowing the trans. I changed the shift points and i didnt even think of it but my hand held has a tach on it so i can check the rpm's on their.
