i'm subscribing to this one. mine is doing the same thing we tried lowering shift timing a little and zeroed out the mph. funny thing is it still shifts the same going to have trans rebuilt and try that but i don't feel it slip or anything, by the way my shift rpm is at 5400 and my limiter is at 7000.

I will say it again, but make a simple change to the 2-3 shift rpm grossly low, and see what happens. I would think your mph is low enough already. You might have the same type of problem I had and maybe your tuner will be able to use that as a hint to find what is wrong (I'd like to know myself).

Since I am now positive that the trans is not the issue (new). I guess it will be time to get it back on the dyno and play with the shift points and see what happens.
I guess in the end I could always go to a totally manual VB in the trans. Would be a pain in the *** but at least that would take care of the problem, right?
Thanks,
Bill

i had the same problem guys lower your shift tie under throttle upshift and downshift most likely the downshift table is still above the upsift table and is confusing the computer.

I have ran into this problem before. The problem lies in the trans speedo table. The speedometer calculation is way off I bet. Mine got skewd after starting with a new PCM reflash from when a shop started over with a different bin file. Mine is also an 01 and I think there were some GM related issues that tie into this.
If you don't have this fixed already shoot me a PM and I'll send you my bin file and can compare these parameters.
Most A4s have over shoot issues when they swap TCs, but if it's that excessive the calculation is off. Just let me know and good luck!

After talking with Sean I took the car out on lunch and tested the car at different throttle amounts. The car shifts with no problems all the way thru 3/4 throttle (estimated 3/4). Once you push to full throttle it bangs the limiter.
So, I hope to get this thing fixed ASAP. I am trying to get the EFI Live file so I can take a closer look at the tables.
Thanks,

My bin file will be there shortly!!!

funny thing is that when mine spins shifts without hitting the rev. when it hooks bangs the hell out of it.
i'll try cutting shift time in half and see if it helps don't think we tried that yet.
Bill let us know what cures it.

Someone may have allready stated this i read through all these the best I could , Im not interested in the 50 dollars , But with the tuning has the line preasure been raised , is there any possibility that rather than slipping or that the shifts not being comanded , Could it be solenoi flooding at WOT due to high line , They can only vent so much and if the cant vent completely then the valve will stay stroked and there will not be a 2-3 shift.
I have wondered if theres any companies out there who make solenods for these with a larger orifice .
if the shifts feel good at every other rpm consider lowering the wot line and see what happens at least down to stock .
