reverse hesitation then slam into gear

just recently my truck has been acting weird when shifting into reverse. only when the motor and trans are up to temp and say after driving home from work. it's 95 auto with 120k with a rebuild at about 80k. when I go to put it in reverse to pull into a parking spot, it hesitates for a second or two then hard shifts into gear. what could this be?

also 1st to 2nd has a hard shift and going into OD it will rev up before engaging (but I can control that with throttle pressure)

I would suggest servicing your transmission .New fluid and filter really does help.While you are at it change the convertor fluid too .BTW Ford recommends doing this at 30 k intervals .

Once you have drained transmission ,convertor, replaced trans filter and installed the pan ,fill your tranny with about 6-8 quarts and start the engine ,your convertor will fill at this point . It is best to do this on a level surface .Now add and check fluid until you are satisfied . I think I ended up with 14 quarts in my 4x4 ,2x2 is less .

I've heard not to, at least going by the posts here on PSO. If you've got nasty particles sitting dormant in the system, a flush can actually exacerbate problems.

When you pick up your filter and fluid, it'd be a good idea to get filter clips- I don't know if they're available at your LAPS (Local Auto Parts Store), but your local $tealership should have them. They ensure the filter stays up snugly against the underside of the trans, because a dropped filter a) can starve the pump, and b) causes no-forward and reverse-stall issues. Bad news all around.
