Hello everyone, I need some advise. I have a 2003 5.9L 3500 4x4 dully(automatic), I had the transmission rebuilt back in Dec 2013. It took my guy a couple of days to get it done and back to me. It drove great then a week or two went by, it was shifting funny so I took it back to him and he reprogrammed everything and some how broke the indicator, and now it don't show up on the dash. When picked it up and it drives worse, and once i got on the highway it will not shift into over drive. So the fastest i can go in it is around 50mph without getting my rpms to high. Took it back, he drove it and said it needs a new valve body, but they are on back order. Been calling him once a week about it. He's a super nice guy with a good business but here it is almost may and its still not fixed. Ive called transmission places and don't seem to have a valve body. Am i getting the run around or can the valve body cause this much problems? I have a 48re transmission. Thanks a lot.
