I was driving home on a really bad night, and my pickup had been slipping and revving up on the 2-3 shift. Next think you know it doesnt shift into 3rd or 4th gear at all. It just revs up and I have to drive in second. Its great. 60 mile drive home at 3 am goin 50mph at 5000rpms. Could this be a servo or am I looking at getting @n@ly raped by another tranny shop. Any ideas would greatly be appreciated. Thanks
