I was going to work and the transmission started slipping when I had cruise control on, and then when I got to a stop light my truck started revving and wouldn’t move. When i put it in neutral it wouldn’t roll either. It just kept on revving and screeching. So i out back into drive and it jerks. Also my trucks rear end locked up and wouldn’t roll in neutral while the truck is on. You have to keep the truck off and then put it into neutral to roll it.
