My diesel stalls when I put it in reverse but runs forward just fine. The transmission was rebuilt 15,000 miles ago and I don't seem to have any problems with it shifting though there is a slight lag between pressing on accelerator and the truck taking off. This started about the same time the reverse stall started.
