I picked up a 2001 X5 a couple months ago with a bad trans, looked like the infamous "A" clutch failure (http://www.xoutpost.com/bmw-sav-foru...x5-issues.html), found a used trans from a running and driving 2001 X5 and picked it up. Today, I finally got around to buttoning it all up, get it started up and it seems forward gears are perfectly fine, but absolutely nothing in reverse. It is still up on jack stands so there is not even any resistance at all on the wheels to spin but still nothing at all in reverse, I would think that even if the trans did have the F clutch piston seal failure that being up in the air I would get at least some movement, but I get nothing at all.

I can't seem to find my scanner right now, ordering a bluetooth scanner off Amazon tonight, so until then I can't even check to see if there are any codes.

Is there any other failures that could cause this that would leave the transmission with no movement at all in reverse?
