Unhappy Nv4500 rebuild?

So i was driving to work Friday and heard a loud pop and lost 5th gear. So i pulled over and looked everything over and didn't see any fluid pouring out so I assumed 5th gear nut spun-off. So today i pulled it apart and the nut was tight, pulled it off and no splines on 15 or the main shaft. Where can i get a good rebuild kit and how hard is it to do?

They arent really hard to do. Lot of posts out there about how to rebuild it. However, end play is very important. Dont get it to tight or will burn up again and too loose will break everything again. PM Rob (Maxtorq) here and he should be able to point you in the right direction. May even have my old 2wd on still in his shop or at the tranny shop where we took it. I ended up just going to NV5600.

I got Amsoil from Herb for mine back when I put a reman NV4500 in my truck. It is a specific fluid, I almost wanna say its a special 75w 90 spec.

Nv4500.com rebuilds and has fluid listed. Same person as High Gear Transmission in Memphis. He used to,have new probably surplus transmissions but those are probably gone.

Decision is time, interest and tools vs money.
2000 Quad Cab,Longbed, NV4500, 410 Gears, 4X4, ISSPro gauges, Thuren 3rd Gen Trackbar (beautiful), AGR Steering Box - box works - NOPE, spoke too soon. Never AGR again. 2 dumped fluid & lost brakes & steering, 4th is too loose. AGR = pp quality control & long wait for replacement (doing something different. Will update with what works), DSS Steering Brace, AirDog 100 = 13# solid, Rusty Doors (POR15 at the bottom for now covered with color match Rustoleum)
