I desperately need some expertise before I pitch myself off a roof. The spine of the tailshaft on my transmission is resting on the bottom of the shifter and is rattling me out of the car at high speed. The damper on the driveshaft also has marks on it where it has contacted the trans tunnel. I put a new trans mount on and it helped the vibration slightly, but something else has to be wrong. It's an LX, 93 with an automatic, and it's been this way since the day I bought it. I'm thinking the u-joints are out as a cause because its a clearance issue thats causing the vibration. Is it possible the motor mounts are installed incorrectly and the engine is sitting too high. If I look across the top of the fender from one side to the other, the top of the EFI seems to be barely clearing the hood. I went to the JY to see if I could get under another car to measure some clearances. They only had an 83 auto, and the tranny mount /crossmember was completely different than mine, so no real help there. Any info someone could provide would be most appreciated.
