It sounds ads the convertor lock up clutch ios going bad on you. The fluid being gray indicates metal in the fluid. You could try to change fluid and filter but you are probably looking at a rebuild.
Hope this helps;

You might need to replace the valve body clip with the upgraded (stronger) one. Ford had problems for a while with the clip breaking and not allowing the tranny to shift into O/D. I had the no O/D problem, I replaced the clip with the upgraded (stronger) one which fixed the problem.

90 ford Taurus 3.0 SOH. engine rattles or shimmies in third and overdrive gear automatic especially when going uphill. When i accelerate it stops or smoothes out. I checked the diagnostic codes and nothing...

Guess I'd have to agree with you. Sounds like the gears might be going bad. But, you might want to check your motor and transmission mounts to see if they are worn and causing the shimmy.
