Hey guys,

I plan on dynoing my 03 5AT soon, but I am not sure what to expect. Im not talking about the numbers, but the ability for the tiptronic to hold a gear. On my model, if I put it in manumatic and into second at around 20mph the car will downshift into first when I floor it. This happens at every speed when there is the option for the transmission to downshift to a lower gear for faster acceleration.

On the dyno, when I want it to stay in fourth, I am afraid that it will just downshift back into first once the pedal goes down.

How do members with 03's dyno their cars? Is there a way to avoid this, or is this a non-issue?

Thanks for the help

 

Why did you post 2 threads?

I didn't see the dyno/tuner section until after I posted this one, and I figured I might get more answers there so I posted it up.

 

Hmm I'm not sure how they do it. I would send a PM to some of the 5AT guys and ask.

 

the easiest thing to do is take it on the highway, put it in the gear you want and test the rpm to see where it will not downshift. i dynoed in both 4th and 3rd in my auto. i remember for 4th, i ran it to about 60mph (dont remember the rpm) and went wot from there. make sure they hit the rev limiter (fuel cut) in whatever gear so you the full rpm range.

 

pre 04.5 ATs are tricky to dyno... mine holds gear by I have heard of 03s having problems... PM DaveO he'll give you the details of what to try.

 

thanks guys, this helps a lot!
