Help!! Yesterday while backing my '87 528e out of the driveway, when I went to put it into 1st, I heard a little grinding then...Kaput...nothing. It feels like the shift linkage isn't even connected (it is, I jacked up the car and looked). Does anyone have any idea what this could be? When I shift through the gears, it won't go into any of them. The clutch feels fine. Any help would be greatly appreciated.
