Any of you guys ever hear of someone swapping the stock engine in a 2003 GMC Yukon Denali for a Duramax/Allison? From what I hear the computer is the biggest problem? Thanks!

Yes, it's doable, but the entire engine wiring must be swapped also. Connecting it back will be a very long and tedious job, that will require a lot of time and a hefty price.

Wait, shuts off but still idles? If you mean does not respond to throttle, this could be a "fly by wire" system which has a gas pedal sender unit prone to failure. "Lokar" makes a nice replacement unit reportedly better than stock.

Will a transmission from 2003 duramax fit in a 2004 duramax?


They will deefinitely providing the 2 are the same model. In 2004 the Allison tranny was available in a 5 or a 6 speed. Before 2004 only the 5 speed was used. If one is changed for the other there will be shifting issues and codes set in both the ECM (engine control computer) and TCM (transmission control computer). Make sure you are putting in a 5 speed Allison tranny.
