You're going to need to open the transmission. Something is bleeding off hydraulic pressure in the REV circuit when the fluid warms up and thins out. That usually means a failed internal seal, valve, frictions, or piston.
Probably rebuild time.

Lucas tranny spooge can help get more miles out of a trans with tired seals. I fill 1/2 way with fresh fluid, start the vehicel, then dump in the Lucas so it mixes. Top off as needed.
Given that a remanned trans costs the same either way, I'd run the aging unit until it really started to tear up.or at least until I had the replacement in hand.

I'm not advocating them in oil, but have used them with known dying automatic transmissions and bought some time that way. The transmissions shifted quicker and performed dramatically better. There was no "placebo effect". In all cases I assumed dying pump and/or weak internal seals.
I haven't tried brake fluid to swell seals, since I don't have a junker handy at the moment, but have heard of that as a temp remedy for dying trannys too. Like running STP or gear oil in a dying engine, this isn't presumed to "fix" the problem for good.
