Need Tranny Help ASAP - Code 00652

[BCC777]

99 2.8 30v Quattro

Tranny is in limp mode and showing code 00652.

Car is in driveway and I'm not sure the entire tranny is bad ....no reverse or if there is something mechanical that can be looked at?

I have folks saying drain a little fluid and see how dark it is and if it smells burnt. If that's the case ...find a new tranny...can that be correct?

Any help would be appreciated

I have a 1998 Audi A6 C5 2.8 Quattro, 142kw ACK engine, ZF5HP19FLA transmission.
Now I have this problem. When I drive on cruise speed my car shifts smoothly thru all gears, BUT if am in a hurry, it goes 1-2-3-4 then,if I hold the gas pedal on 2000rpm or low, it shifts smoothly to 5th gear, BUT if I push the 4th gear above 2000rpm, it slips and goes into LIMP mode....until OFF & ON.
After driving like for about two years I decided to throw in another transmission and behold...exactly the same problem as the former.
I have tried another TCM on it....same issue.
VCDS suggested changing the Multifunction switch(F125), that I have not done.

Are you sure you filled the transmission correctly? ie: fill the pan while engine is running with fluid being cold to warm (not too hot)?
