Sorry, Ford Shop Manuals only show a Aisin AW21, FNR5 or 6F35 going back all the way.

Okay. In Post #134 you state that it happens before you reach a constant speed, correct? If so, the TCC wouldn't be locking up or shouldn't then.

Okay, I see that now. I actually replied to that post where they disconnected the plug at the rear end, the hard way to do it. There is a so-called "hoot" sound first heard from the rear of the '09 4WD Escape, TSB to reprogram didn't help. later said to be in 4WD, FWD, I4 and V6 from drive chain in transaxle. The replaced chain only works for a short and the noise returns. Owner's are being told it's normal now. Pulling the fuse for the 4WD module stops the sound. Go figure...

At last, an answer. Thanks.

What??? Is that a typo??? Is supposed to engaged/disengaged when the system detects the need or lack of. They do wind tunnel test and add things for less than a 1mpg gain. Look at the front edge of the rear wheel well on a >09' Escape some time. The little rubber piece was added for very little mpg gain but it was added never the less.

That doesn't answer the question, did you try that? It would prove/disprove the engage/TCC claim.

Okay, I just reread a bit of this thread. I do remember it now. Bet nobody has tried the simple test of pulling the fuse on the 4WD/AWD module to see if the problem persists?

If this thread description is accurate or 1500rpm@40mph which sounds like a constant speed has been reached. By that time the rearend has disengaged. It happens well below that speed.

Not for TC but if there was a simple way to disable the AWD, it would.

Huh! That will defeat your 4WD/AWD rearend ATC unit. If that stops your problem, you need a new rearend, they aren't servicable.

That's the hard way! Just pull the fuse to disable the 4WD/AWD module.

You heard wrong. Your AWD/4WD kicks in every time you leave from a dead stop no matter what the driving conditions are.

Ford's plans are to start building those rearends in house instead of purchasing them from Dana. They will be building them at Ford's Sterling Heights, MI Gear and Axle Plant. That project has been going on for some time but I have no idea when the launch date is.

Nothing at all. It was your Tag Team partner that was trying to explain a open differtential working with TC and I incorrectly stated that it pulsed the brakes which it doesn't. Actually Ford thinks AWD means a 4WD with TC.

It says what I stated. If your trying to make the point that I said "pulsing the brakes" instead of "pulsing the brake pressure"? I did and that was incorrect.
