4x4 Th350 Non lockup Need help
Ok heres the story...... I bought a 1983 k10 pickup from my girlfriends dad. It had been sitting in his backyard for 3 years after the rearend went out. He had had the transmission rebuilt 5000 miles before parked (saw receipt). When I first fired up the truck the trans was 3 qts low ( leaking from pan) so I filled it up. I now have reverse and nothing else. It makes the engagement movement when put in reverse but not in any other gear feels like it is in neutral in D, 3, 2, and 1st. I have dropped the pan and replaced the filter. There was no cluch material in the pan. I pulled the vac line off the modulator on the back of the trans full vac is there and no signs of tranny fluid. Does anyone have any ideas to what the problem could be? I was leaning towards sticking valves in the valve body or a bad valve body all together but then again I have no idea. Any and all help is much appreciated.
