I have a 2002 BMW 525i and I ordered an automatic transmission

Customer Question

I have a 2002 BMW 525i and I ordered an automatic transmission for it but they sent me the wrong one. It was installed after the time that I could send it back. I wanted to know if I got the transmission computer that was compatible to thettransmission that I have, will it work because it does bolt up and everything fits. They sent me a GM transmission and the other one is the foreign transmission. The GM transmission has internal range sensor and the other one has external range sensor. Can you tell me if I change the computer to the GM transmission will it work?
JA: Good to know. The mechanics have tons of experience dealing with this sort of thing. How old is your transmission?
Customer: The new one is 2003
JA: Ok. We'll get you to one of the go-to transmission guys. Other than the problems you mentioned, how has the car been running?
Customer: Car is great
JA: Noted. I'll pass this info along to the mechanic so that he can get you a quick fix. Anything else I can tell the BMW Mechanic before I connect you two?
Customer: Can the external wireing be wired to the internal wiring
JA: Got it. Let's get this figured out. I'm sending you to a secure page on JustAnswer so you can place the $5 fully refundable deposit now. While you're filling out that form, I'll tell the BMW Mechanic about your situation and connect you two. You'll be on the road in no time.
