Hey guys... Since I'm not married to Diesel Chick...

What's up with the heavy vibrations coming from the transmission? Is this a serious issue with the torque converter (or something else)? Could this be an overfilled transmission?

My wife tells me she shouldn't have to put it in Neutral when she's at a stoplight. (I had to let her drive it while she got her standard 70K transmission replacement in her Chevy Truck.)

Plan to swap out fluid and filter tomorrow.

Any help would be greatly appreciated.
