My engine rocks and shakes the whole car!! Need Suggestions!!

Like memike said. Transmission area. Auto? Maybe loose converter bolts?

Yep, auto trans!! Actually, in the spirit of fixing things on this car, I'm pulling the trans next and replacing the shift lever pivot seal, which has also been leaking for at least 5 years!!ARRGH!! I also have a new converter to install so that'll give me time to check all the trans stuff!! Thanks for the input!! Geof
