Description : I'm experiencing no 2-3 shift in a transmisssion that I just put in my truck. It worked fine for about two days then not 2-3 shift. History: transmission sat dry for about two years. This seems to be an issue with the 5.4 Triton coupled with the 4R100 transmission in the 4WD F250-F350 Super Duty Series for Ford manufactured from 1999-2004. I am not a mechanic as you will see in additional posts. I am just a farmer and this is the first automatic transmission I have ever cracked.
