Figured I'd post up again to get people's opinion before actually taking the time to examine the car. I had 3.73 gears installed on my 98 Z28 Auto. They said the backlash is perfect when I had a local college set it up. I am thinking I have a bad transmission mount or motor mount. Basically I get a "clunk" when I put the car into gear and I have a shift kit installed... Normal driving from like 1st to 2nd gear it bangs kind of hard and this problem shows more often. If I cycle from reverse to drive setting still and don't have my foot really hard on the brake, it thuds and seems something in the drivetrain is not right. A lot of my friends said it seems like a bad transmission mount... What are the symptoms of this, anyone know? Let me know, I kind of wanted to know for sure before getting under the car and checking it out for more detail.

Bad trans mount, broken torque arm, loose drive shaft bolts, bad u-joints. I would rack the car and have someone shift the gears while you are underneath it to look and listen for your mystery clunk.
