Hey guys, putting together a little project trail rig. on Chevy 1 tons, dana 300 tcase, 5:38 gears, and 4.1 in the 300. Putting in a 4.3 currently and trying to decide which tranny would be the best? If you could shed some light it will be appreciated. Also I would like to know whats the best upgrades/necessary things to do to an automatic tranny for steep climbs and crawling, thanks guys!!
