Just took my car (2000 C5 A4), out & about for some killer jaunts & noticed that in 3rd, @ WOT my car would hit the rev limiter on the 2-3 shift, but when it was in D, WOT it shifted 2-3 fine..

ANY idea whats going on?
I don't think there was any wheel spin.

My buddy who was logging me as well, and lost communication every time it happened.
There was also a blip of the check engine light, but no codes..

Very strange..

This happens ometimes as the overun clutch is coming back on and sometimes causes a presure drop when in the 3rd not the OD position. When manually shifting try skipping the 3 position before time for the 2-3 upshift, Though the scanner thing could also point to and electrical problem I would try the shift thing first .

I wasn't manually shifting.

I was trying to simulate how I run at the track, in 3rd...

UPDATE:

Went to the track tonight, ALL CLEAN runs..
No shifting issues at all in 3..
The 2-3 shift was crisp & flawless...

Can I chalk this up to wheel spin on the street at high rpms?

I actually ment this happens in the 3RD position which i considered a manul selection . But if its ok now may have been some odd electrical quirp or maybe spinning at high RPM ? But all thats important for now is its working so good for you
