Check to make sure you don't have the TOW/HAUL switch on the end of the tranny stalk turned on

Why wont my 2001 gmc sierra 2500hd go into 4th gear?


There is a speed/shift sensor you could change, but if you haven't changed the fuel filter in a while, i'd go there first. Sometimes, in fact, often, plugged fuel filters can cause the engine to starve for fuel, and make it seem like the transmission is the problem.
