OK well I've had my transgo shift kit installed for almost 2 weeks now and all of a sudden the car drives funny. when i turn the OD off she drives fine, but since I always drive with it on to save gas its not shifting into 4th. when i get up to around 50 or so she just starts revving as if its in neutral. once it gets back down to around 20 it drives fine. the shop that installed the shift kit is saying i fried the tranny and it prolly needs a rebuild. what could be the problem? cuz im thinking that if the trannys fried, it wouldnt drive at all.
