2002 VR6 Manual Transmission - Doesn't shift into Reverse anymore. No noise from transmission, or engine bay area. No smoke. No leaks. Allows me to shift into where Reverse should be, but only seems to engage 1st gear...treats it like I didn't go over far enough for Reverse.

The whole car vibrates when trying to reverse.
I pulled into my driveway and my car won't go in reverse. I think linkage is out.

Sometimes reverse gear does not work until I put it back in neutral, let off the clutch, press clutch again, then shift into reverse. Also I get a clunking noise sometimes when shifting.
