I have an 01 cummins with a built 47rh. Goerend parts. It has a high stall tc, I think the number was 3200. When shifting from park or neutral to drive or reverse the truck bucks then stalls out. I have to pretty much neutral drop it and keep my foot on the throttle for a few seconds then it clears up and shifts fine. I can drive to a stop sign or whatever and stop and it stays running like normal. Only happens when innitially shifting into forward or reverse gears. Talked to goerend when I bought the truck with everything already installed and they said it was because it's a higher stall tc. But it has gotten dramatically worse since then. It also will not shift into overdrive. It runs through the gears up and down just fine just won't hit overdrive. I changed governed pressure sensor and another solenoid and also the filter. Other than that the trans works great. Any help would be awesome. I'm out of ideas.
