04 CHEVROLET GMC SIERRA SILVERADO 2500HD 4wd ALLISON 5SP AUTO TRANSMISSION LLY

Here we have a good used 4wd 5sp allison transmission assembly removed from a 2004 GMC 2500hd. There is no damage to this transmission and it is fully functioning, it was removed from a running and driving truck. This should fit all 04.5-05 trucks with the LLY diesel engine. Make sure this part will work for your truck BEFORE purchasing.
