Rebuilt Transmission Question.

[Weasel]

There are many things that can cause a shudder feel, and the best way to track it down is physical diagnosis. I would first call your service adviser and explain the problem and express to him that you would prefer one of the more experienced techs (master tech) to diagnose it and to do a complete enough diagnosis to have confirmed the actual cause before throwing up an estimate for transmission. (I personally have driven around with my shop foreman in the passenger seat holding the diagnostic tester in his lap to observe the torque converter lockup clutch circuit via TC speed vs engine speed to confirm my diagnosis)

That's the way I will go.The only problem here is that the dealership is just about 3 years old,this town had none for few decades.

Well, then their most experienced, thorough and quality minded tech is the best they can do for you.

I just wrote a technical inquiry to ZF Canada.
Will see what they've got to say about it.

Ask them about the diff rubber mounts and I know how you feel and I had the spark plugs changed with no luck, I also had the MAF replaced with no luck so now it seems to come down to either the diff mounts so thats my next $tep. Other than that the X5 drives beautiful and safe.

I doubt that they have an answer about the differential mounts,that would be more BMW dealership question.I really doubt about the mounts.
More like transmission related thing to me.
Do they offer a full refund if changing the mounts doesn't solve the problem ?

Lol, If that they had a refund policy like that I would have already jumped on the repair, I doubted it myself but then again I aint no tech and thats why Im posting here. Let me know your outcome, Ill keep posted. GL

After 1 year and a half of waiting for a right time to drop it for warranty repair and ultimately,convincing the shop mechanic that shudder isn't what I am gonna live with,I got the X back without any shudder,the TC was redone under warranty,also they claim that there was some kind of bushing or what ever it is in some shaft,I don't really care since right now I have it running the way it should run after a tranny rebuild.
Knocking the wood and hoping to forget the way to the shop.
