[MasterJacko96]

when i punch or go WOT in the car i might buy it pretty much hit the revlimiter a few times before it shifts. it doesnt slip at all im just wondering what the problem might be. bszopi suggested it could be the kickdown cable but he said that i should ask here. please help me out if you can thanks

If you think thats the problem..Check the TB to TV cable slack by opening the TB wide open. Theres should be little slack...if its tight..then it needs to be lossened up. YOu might want to try it without it connected...just to check if the tranny is becoming lazy at shifting. You might also want to check the vacume modual. The only way I know is by air testing it if it could hold pressure.
