If it gets worse with warmer engine (ATF fluid) temps, then I would guess it's either a line pressure issue, or a problem with the overdrive itself.
In any case, I think you might need a tranny specialist on this one.

If the O/D off light starting flashing, there is some internal problem. At least the computer is telling you, before it takes a dump on you. On my Windstar, it threw a couple of codes. A piston inside was not right, and something else. Time for a trip to the transmission shop.

well, gentelmen, lets try to solve problems with tranny on truck first. What we can do? Ajust OD band, change OD piston, its internal sealing (2 o rings on "stick").
well, we can also drop valve body and change some valves, pistons... the next step is to drop a tranny.
but ones I pulled out OD servo piston and 2 small part fall down in tranny and I had to drop tranny anyway.
Well, OD band change requires to remove bellhousing and valve body. so 3 new gaskets... so there is a reson to change OD clutch pack too.
ok! but... as experience say, do all tranny rebuild, becouse I changed OD band first and got 2nd gear sliping, chnged band #2.... and a year later I got no reverse becouse of worn band, so there is reason to change all and be sure your tranny will run fine for next 5 ore more years.
