X5 transmission control module replacement..

[turquise1]

Hey guys,

After trying pretty much everything (except the tranny itself which the mechanic says is working fine) I was told to replace the Transmission Control Module to a new/updated one.

I am also told that I cannot use a used one and had to get a new one and get it programmed at the dealer around $1000 (BMW X5 01 4.4 at 172k miles). Is that correct? Am I really stuck with that option? I am asking this because I remember reading some other people using used modules on their BMW's..

Thanks for all the help..

Ozzie..
