Hey smassey, thanks for the information.

Im still waiting on that Carly adaptor ive ordered. Will that app be enough to gather such detailed data from the faults stored in the ECU? Or should I get a different diagnostic device?

I wish it were the solenoids, cause its a relatively easy and "cheap" fix when compared to the other alternatives.

You will need a rebuild. Or you should.

The trans has been failing for quite some time...parts have been worn and stressed, crap has been distributed. Getting a 'rifle shot' diagnosis of 'which bushing is bad' then only replacing that will be foolish.

When they opened it up and reported 'lots of contamination', that is the death knell. "Contamination" is actually "pieces of the internal transmission components"...

Sry
The ZF shops youve talked to should be able to do this. Labor is remove and reinstall transmission- then to do the rebuild. Just a guess, but here probably 5k-7k US$

How much money did you waste on the "BMW professionals"?

I see. I've spent 2K+ euros already just for that issue. I was quoted a reman trans straight from ZF with warranty should cost approx 3.5K from that BMW dealership, not sure if that includes labor. I should've just bit the bullet and went with a remanufactured from the start and be done with it or went straight to a ZF specialist.

Maybe selling and moving on is the appropriate course of action? Bad thing is I really like this truck. I was planning on getting a new F15 in a year or two since i'm in the middle of an expansion in my business right now and would rather not stretch things - I do not finance my vehicles.

I'm just so disappointed. Only 45k miles on the clock.
