I have a 98 SVT and have replaced the tranny before but it is doing something i consider slipping. It only happens when I turn even a little bit. the car like slips then grabs until i go straight again. The guy that replaced the tranny said that i was putting in the forth tranny and the car only just turned over 28000. this is really getting me mad

so I was wondering if someone could tell me what is wrong before i go to the shop or if it is possible to get a more HD tranny. The Clutch was just replaced 2000 miles ago. Thanks.
