I have a 4900 with dt466e and the transmission has 5th gear completely gone. What I'm trying to figure out is can you put something other then a spicer 6+1 transmission back in it? I have found a spicer 10 speed for a descent price and would like to put it in there for a few extra gears since I'm going to install a new one anyways. I haven't pulled mine yet but from what I have read the medium duty trucks have a 1-3/4" shaft and the heavy duty trucks have a 2". Other then that my knowledge is pretty limited on these transmissions. I have attached a picture of the data plate on my transmission.
