transmission - a mind of its own!!

[HSV2006]

Folks, what searching I did of the archives did not reveal a problem like this. If it's been previously covered, I apologize - but it was not there to easily find.

Here's the issue. My '02 X5 4.4 transmission has a mind of its own.
You can be cruising at 55 MPH, and it decides it wants to be in 4th, or even 3rd! That's one example of this odd behavior.

In city driving, say at 45 MPH, I can let off the accelerator to slow down for a traffic signal. The transmission will downshift, slowing the vehicle down through each gear, to 2nd gear.

These "actions" are quite random. I've no clue. A possessed unit?? LOL!

SO... any ideas? What's the scoop?

Oh. I did try the "transmission reset" - to no avail.

Thanks!

Kim
