That's what I'm going to do to mine whenever the four gives up the ghost, if I ever get time! The GM auto has overdrive plus lower gears, the transfer case chain is slightly wider too. I already have the complete drive train, but I have several other projects in front of it, so it will be a while before I get around to it. The four does what I need it to do, so I'm not rushed. I do mostly woods crawling with it, so the four is more than enough for now.
