shifting prob?
I just bought an ALL stock '01 nhra formula with and auto. It has 80K and was driven all highway miles by a woman to work a long distance away daily. I know the history on the car so i gave a premium price. However, as soon as i got it i had to do some full throttle launches. Is there a problem? Here are the symptoms. If I take off from a dead stop, wheelspin is inevitable and every time it hits the rev limiter 2 or 3 times before shifting and then it seems like it is about to die. Could the dying be from hitting second at about 15 mph? Any help or preventative maintenance tips would be appreciated.

Well you are bouncing off the rev limiter. Not to sound like an ***, but it seems to me like you don't know how to launch your car. If you are shifting into second at 15mph to keep it from spinning you need to relax on the 5k rpm clutch dumps.

A4
The car is an A4 so it does the shiftin all its own. But the help is appreciated. Also, is there any way to lower the rev limiter, it sounds kinda tough on the motor at 6300. But what i was sayin is that it hits the rev limiter between the 1-2 shift. Any input on that would help a lot bc that seems abnormal.

Auto's can hit the rev limiter??
It seems as if the whole advantage to haveing a auto would be not having to shift, and if the ****** thing doesn't actually 'shift' before the rev limiter, it seems like of pointless.

i dont own an A4 but ive drivin a few ls1 fbody's with A4's
and what ive noticed is that it wont do it most of the time. but if your beatin on it repeatedlypretty good then it will start to do it more, like the warmer the tranny gets.

So in a A4 you cant punch it and burn through first and second? Im not even going to comment on that.... I Thought the shifting was based on teh RPM's of the motor, not the rate at which the tires are spinning...

Back to the question of the thread, my friend had this problem with his auto for a long time. His wheels would spin a lot faster than his car could shift, and consequently he hit the rev limiter a lot. Good tires and a tune fixed it, and we haven't had problems with it since.
I wouldn't drive the **** out of it and let it just hit the limiter though. It doesn't happen a lot, but hitting the limiter in an auto can bend pushrods. If you want to get on it, I would suggest feathering the gas a bit until it grabs. So good luck with it man. For us it was as simple as tires and a tune.

As soon as I had the Nittos put on and the tune corrected, (the tranny tune wasnt exactly perfect before hand) I havent hit the limiter once going into 2nd. If it was third I'd be more worried about being low on ATF or the 2-3 clutch pack. The transmission will shift off of MPH and RPM at any given percent of throttle, for example there is a different table for 10% throttle opposed to 100%. So the best bet, dude get some tires and quit holding it down when you hit the limiter, the car will only take it so much, bouncing off of the limiter 3x until it shifts is a bad idea.

Haha, Reza I had no idea that was you for about 10 minutes. I guess they finally did your name.
Yeah if it hits the limiter from 2-3 you need to check your fluid and clutch packs. Trust is right. You don't want to rag on the limiter very much. But I think tires will help a ton.
