Sounds like a transmission problem to me.
I thought about posting this in the hot rod thread, but it would be easier to manage here.
1967 Chevy C10, turbo 400 trans. The truck sits a lot. It won't go into gear, unless you step on the gas and let the revs come down. It slips back out of gear if you give it a lot of gas.

Forward, reverse or both? We had issues with my '84 suburban that has the TH400 not wanting to go into reverse. Turns out the tube that picks up the fluid had fallen off and was laying in the pan.
We need some pics of the 67 C10... Love the old trucks.
My google fu says front band is sticking. So it's enguaged? I'm thinking the servo isn't engaging to press the band.

Maybe I can run transmission fluid through it to clean it out.
Might look into the Lucas transmission stuff. I use their power steering additive and that stuff works! My guy at NAPA said customers have had good luck with the trans additive as well.
I watched a video of a teardown. Customer's car sat for a while. It's a Rolls but still a T400. The valve body sprung up when he took the last bolt out, because the plastic servo was in half, leaking of course, and the spring inside the 2 halves sprung up the valve body.
I think the stuck band pushed his servo in half. It couldn't press it shut, so it pressed the servo in half.
Which goes to show, don't leave a car sit around.
