I have a 2005 Chevy Avalanche 4x4 6.0L LQ4 engine, transmission and transfer case. I want to put this in an older 2 wheel drive GMC truck and need to know what can be done to remove the transfer case and add a tail section on the 4L60E that will convert it to a "normal" transmission without the transfer case. Can someone point me in the right direction for information and pricing?
Sell the transmission and transfer case as a unit and use the money to buy a nice built transmission. You can convert it but you'll have to tear it all the way down to change out the output shaft to a 2WD unit and then buy a tailshaft housing. The labor alone will cost you about $300 unless you do it yourself and then add in the parts. You can get used parts for about $100 for the two parts. Used is best because you'll probably get the sensors and pickups with the tailshaft housing. Surely somewhere in your area is a company that sources core engines and transmission for rebuild shops. In Dallas we have Bishop Industries.
No offense but there has never been a 6.0 put into a Avalanche by GM. They are promising that one will be available mid year on the 2007 model but not yet.
Todate, Every 1500 AV ever built has a 5.3 with a 4L60 and every 2500 has a 8.1 with a 4L80 from the factory.
