NV3500 Disassembly Info Rambletron GMt800 s10 LONG

I learn how to disassemble a 2wd nv3500 new venture type I think it is what it is called. From my limited knowledge and info I want to say the getrag version is similar in some manners. In my case was fixing a trans with reverse issues. Feel free to comment or add any info I left out. Thanks
