Hi all, I have a problem with a bmw x3 3.0 sd with an automatic transmission, you have low engine rpm acceleration feels a slip right under the exchange the same that attaches and detaches the transmission I did some research on the web and I have seen that many write that they have changed the tires the other the transfer case and many others the starter motor which is located on the back of the gearbox, but to be sure that I can check if the distributor or the chain or the starter motor and lingranaggio. I like the fact never someone can help me I'll wait for your answers
