My roomate has a 94 z with an A4 tranny and when he floors it the pulls hard to the rev limiter and bounces until he lets off the gas and then it shifts. When he drives normal it shifts normally. WTF??

Bad tranny. The clutches in it are burnt. That is causeing it to slip when it is floored.

 

if he has gear or a stall that will cause it to bounce the limiter without a tune but if not trans is on its last leg

 

Not trying to start an arguement, but the tranny is controlled bythe computer and will change gears at a certain RPM regardless of the gears or stall

 

You would think so. Ever since I upgraded my gears and TC my tranny will bounce off the rev limiter from the 2nd to 3r shift 2 or 3 times.

your tranny is going out too. mine went out when idone gears. these stock trannies suck

 

the gears and stall causes alot of stress on the tranny. the stock tranny cant handle it and starts to slip. it will get worse.

 

The gearing and tc are both stock. So what you are telling me is that i need to give him the bad news? Sucks for him

 

yep tell him it is bad. what state are yall in?

 

Thanks for the help everybody. Boy is he going to hate to hear that.

We both go to Texas A&M University in College Station Texas

 

Is there anything he can do to make it last longer? is it possibly low on tranny fluid and would that cause the problem?


Tim

 

It may be low on fluid. I assumed that had been checked. My bad. If the tranny is going bad..........the only thing that will help it is to take it easy on the gas.

 

thiw may not be related but i hear a shift kit helps strengthen ur tranny, would that help relive some of teh stress on teh tranny from a T/C and gears...or is there no help but a built tranny ?

 

I dont know if a shift kit would help to strengthen a tranny

 

I would jump back in that car at WOT and take it up the RPM band without hitting the limiter and see how it shifts through the gears before ruling out that he has a bad tranny. Is he using Dextron? I dont think he's allowing the tranny enoughtime to shift at high RPM so gets spooked he just lets off. Before my firm shift tune..my car sounds like it was doing the thing as your buddies...I would take it to the limit and since the stock shift is so soft..it kinda takes a few seconds but I wait until it shifts finally. I got sick of that so I did a tune and added a firm shift and my car seems to be WAY better at shifting when progressing to high RPM at WOT. I thought I had a different car...anyhow I use Dextron and I noticed a better shift with it over other brands I have used as well. I would totally try some options before telling him bad news that might not be so sure...
