Did this guy say the trans worked after the rebuild? If someone rebuilt it and haven't tried it out yet, I say its a good possibility someone tore a drum seal. If you know it worked good after the build for sure, then you can pursue other possibilites. Low Pump Pressure can cause this too in a Th350.
My guess is going to be the Direct Clutch pack isn't working somehow. Whether that be a piston seal, a clog, a valve, whatever the case. Bummer that my Flow Charts are packed up and I don't even have a clue for certain where they're at.
He said it worked but at this point who knows what the true story is. If the valve body swap doesn't work I am going to see about rebuilding my old Transmission if I can sort out the tail housing bolt issue. If that is beyond repair I am going to go with a 700R4 swap with a 241C behind it and ditch the 203 so that I can have the best of both worlds with lower low range and overdrive. with the 3.08 ratio in the axles and the od of the 700R4 I should be able to get some decent fuel mileage with it. I still have a lot of work to do before it is roadworthy anyway.
Thank you to everyone that has tried to help me with this issue. It was good to learn some new stuff.
