I thought of this thread the other day after a new thing happened.

I got a customer car in that actually used to belong to me. Last year I tore apart the tailshaft of the trans and replaced the clutches, and the Duty solenoid. The car STILL exhibited some excessive torque bind after the repair, as well as sometimes codes.

It wasn't a total lock, just a little brake effect turning into parking spots. Si the customer lived with it, and I checked it over a few more times.

So this time when she brought it in, I thought hey......for S+G I'll put a different TCU in it.


So I put he old one back in to test.


So it seems the problem the whole time was a bad connector for the TCU. After unhooking and reconnecting it must have made a better connection.....cause the car runs great.....no more TB or codes.

So maybe you should try disconnecting and reconnecting your TCU.

I'm bowing out of this one. KNowing very well how the 4eat works and the AWD if you wish to chase things down knock yourself out.


Okay Nipper, Thanks for all the help. I really do appreceiate everyones time and ideas. That is how problems get solved, many minds working in many ways.

The AWD is still working. One thing I forgot to mention is that I did unplug and plug in big connector between the motor and tranny before the AWD started to work properly.
