Does anyone know a good way or resource for how to check my 727 and np229 to make sure they are serviceable short of tearing them down? I got my 89 GW running but it wouldn’t move after installing a new to me transmission. I think a new torque converter will fix the problem but I want to make sure that the transfer case and transmission are in general working order…
I would assume I need to vacuum check the valve body, but honestly this has gotten me stumped… Transmissions are my weaknesses and I need some help.
Thanks everyone!
