Guess what - Tranny Problems

[wifegottheX]

Here we go again!!

I have a 01 X5 4.4 w/ 86K on it. The tranny slips only when i put it in sport mode between 1st and 2nd. I was thinking about doing the following.

Tranny flush w/ filter
Throttle adaption procedure
Clean out the switches in the center console (gear switch and sport mode switch)

I was also reading that some people are having to have a wiring harness and control module replaced. Is that the main harness that is inside the tranny pan, and the main computer for the tranny?

Do you have any other ideas that i could look at before throwing in the towel?

Thanks for any help!
