I have had a 325is stored for 25 years. Got it running. Everything seems to be ok running. The manual transmission will not shift into reverse. 1 thru 5 work ok. I have the shift linkage removed, but still can't get it to shift. When I turn the arm ccw it just goes to the path for 1st and 2nd. It will not turn far enough to allow reverse. It all work fine when parked years ago.
