I'm posting this in the general truck talk area because the driveline thread seems to be down. I need your help, guys & gals. I reassembled my SM420 tranny for my '40 and the countergear assy seems to be locked up, nice & solid like. Everything else turns just fine. This thing only goes together one way, so I'm wondering what I could have done that's locking this baby up. I replaced all bearings when I rebuilt it. Thanks for your help.
