    Possibly killed my first 60e

    Well early Monday morning (around 3:30am) I got off work and went to go pickup my little one from my inlaws. On the way I think I did one wot pull Rollin into it after I got going from a stop light just to mess around. Well drove normal after that and stoped at a light and went to turn onto their road and the gov lock came apart...I put it in 4hi to ge me off the road and I had nothing in drive. I pushed it off the road and looked under it turned it off and on tried changing transfercase selections. Finally manually put it in first and I was able to go and had second also. So I picked her up and decided to limp it the 7ish miles home. Got up the road had manual first second and third but nothing at all in drive. Left it in 3rd when I came to a light and again wouldn't go from a stop but I have it if I manually shift to it while driving. I've got another rear for it lined up since it busted the housing when it went and once I get it in I can diagnose a little more but from my readings I may have broken the forward sprag. If I'm wrong please correct me or if anyone has any input that would be great. Looks like my tax return will go towards a built trans finally lol

    You did some good research. It is without a doubt the input (forward) sprag. In M1&M2 the the overrun clutch is applied which bypasses the sprag and provides engine braking. In D3, the overruns are not applied until it reaches 3rd gear. Sorry for your luck bud. I just had to build the Trans in my cummins so I feel your pain, lol. Spent $2500+ all parts!
