OK guys after reading this thread I went over to my buddys house and asked him about high mileage trannys. He is a transmission mech. and has many years under his belt. He told me if you have not serviced your trans. in over 75,000 mi. or so you should just drop the pan and change the filter. He said don't do a fluid exchange as it will shock your tranny going from old fluid to new. He also said when doing a fluid exchange on high mileage cars he has seen people have many problems afterwards. He recommends once you drop the pan and change filter to continue serviceing it this way every 20,000mi. after. And you should avoid any problems. I happen to think this is pretty good advice.

I think 20000 is a bit soon, except for the first change. By that I mean that you should change the fluid and filter on a new or rebuilt tranny at about 15000 miles, then every 30000 after that. Theory is that the clutch packs give off a lot of dust during those first 15000 miles, more so than later.

As far as doing a fluid exchange on a tranny with 75000 miles, I think the theory is that the solvent effect of the fresh fluid knocks loose some congealed goo, and the exchange lodges it somewhere in a small passage causing a problem. Change your fluid regularly and the exchange should be fine, so long as you also change the filter.

Moonpie what did you decide to do?

See, i'm kinda in the same spot,
95-XLT 122k miles, and for the life of me, can't remember if the tranny fluid ever got changed. it's doing fine, no problems, called local firestone, they say they won't work on any car over 65k because of the possibility of the tranny hurting after a fluid exchange from the posts above.

so i'm not sure what to do, don't do anything or get it flushed?? any recommendations?

aamco wants $125 to diagnostic and flush/refill tranny fluid.
