92 5.0 My trans skips when I am in overdrive going up a hill in a low rpm. This is the only time it does this. Anyone know anything about this?

don't know your mileage, but i would suggest draining the whole tranny, changing the filter, refill(about 12-13 qts) using mercon V and ford friction modifier, and i bet that will help. mervon V is safe in the aod...i have been using it for awhile, and others have too with no complications. just make sure you get ALL of the merc. III out first.

How do you make sure you get all of the merc. III out? My car has 86K it had 75K when I got it two years ago. I have never changed the fluid.

drop the pan. then pull t.c. plug and let that drain. that should get most of it. to do it completely, you can drop the valve body as well, as that hides some too. just a matter of about 10 screws. you can probably get away without doing the vb though, if you don't want to get that involved.
