My TH350 was about to crap out on me totally, reverse was slipping, and I only had first gear, so it was time for a change. I opted for a manual tranny because I run a lot of mud and like to get the gears where I want them and be able to just drop the clutch if I become stuck. I located a transmission and transfer case in Colorado, it was a SM465/NP241 combo from an 89 K5.
