Just got 4.10 gears installed and my cat back exhaust. Before i had these installed i was running 10 flats in the 1/8. Now I am running 9.8. i thought with all this, i would be running better. I have an AOD and when i have the pedel to the floor and try to shift at 5500 it won't shift and keeps on going up to like 7000 until i let up and then it shifts. It shifts fine if i am not on it. Is this my trans and around how much would it be if i had to get it rebuilt. Thanks for all the suggestions.
