My car is a 2000 T/A Auto, Hey guys seriously odd problem, Ok had a transmission mount replaced about a week ago, no problems maybe a slight jutter when put in reverse and then into drive, this morning someone backed into me at walmart with a ball hitch and busted a fist size hole in the fiberglass right beside the QTR panel AND DROVE OFF ARGGGGG thank god for full coverage insurance, but anyways when I was driving it home the car was driving weird, felt like no power was being transferred to the rear, anything about 3000rpms slipped and sometimes it just slipped all together and wouldnt give power to the wheels. Odd coinsidence or could something have knocked loose or the mount been bad, he did use the mount off of a 97 I belive my T/A is a 2000, the car will go into reverse in my driveway and also will go into drive and go forward no problems now..... any ideas ? Fluid Level is good also checked it first thing
