Transmission will not ingage into drive

Hi welcome to 2CarPros.

Have you plugged in a scanner to see if you have any transmission codes?

Here is a guide to get you started:

Did plug in scanner but no codes came up.

Transmissions are tough to diagnose because many things can cause the same symptoms and 90% of those things are inside it. Based on what you are telling me I would say the most likely would be the internal seals dried out and cracked and you are losing internal pressure which would require a rebuild.

It is possible but less likely that a valve in the valve body is hanging up. You could drop the valve body and go through it as a last ditch effort before dropping the transmission.

Newer seals can sit but once they get this kind of mileage on them they dry out and the only thing that keeps them alive is the hot oil they are continuously soaked in. When that stops they simply shrink and crack.

Let me know what you find out or if you need any help with the valve body.

Luckily one of my dad old friends showed up for a visit and he is a 35 year transmission re-builder. So I asked him and he said that the clutch plates are notorious for crumbling in this transmission.So we are going to pull it out and he is going to tear it apart and see what he can find out.I will post updates as it goes.Maybe a few weeks as I am installing a new motor in my 1987 Buick.

Great, keep us posted. We like to know what goes wrong so we can log it to the memory banks.
