But that is if something goes wrong now, my question is what, if anything, can/would they do to prevent/fix it before it fails? Knowing that it is a common problem.

ohhh...i don't think that there's anything they could do but maintain it...when it dies, it just dies...i'm saying nothing but, the transmission is made by gm, no?

the transmission is made by gm?? no fraking wonder

i'm pretty sure it's made by gm...for the pre-facelift and the 3.0 facelift Xs...or the V8s may be, or may not be...but i think the 3.0 4.4 and 4.6 had the same transmission... the six-speed trannys are made by zf.

No, the prefacelift X5 4.4's have ZF 5-speed autos (A5S440Z) while the 3.0i's have French made GM 5-speed autos (A5S390R-GM5).

thanks for the clarification :thumbup:

but now...are both vulnerable to the failure?

Why not go and hire something nice for the day?

Best case scenario: Water in the underhood electronics affecting transmission controller.

Worst case scenario: Failed transmission.

ooo...you can rent a ferrari for $500 a day...but i think that's almost your entire budget wasted on one day...but that would be awesome :thumbup:

but renting a nice car is expensive...something like a cadillac dts is $100 a day :rolleyes: and BMW loaners are FREE!!! ;)

While 115K isn't insane mileage and a trans shouldn't go at that point, it is certainly possible after 100,000 miles to have issues with large components.

Sorry about the bad luck.
