The driveshaft bushing on the back of my '87 190D failed and the driveshaft bounced around and broke off the mount tab at the back of the trans. I have another (bad) tranny and I'd like to swap the back part of the transmission that has that tab on it. How do I get it off? I removed all the bolts but it won't budge. Do I have to remove the driveshaft yoke, and if so, HOW??
