yep, it likely will. black fluid indicates component failure.

First of all, any BLACK FLUID is not good.

I hope you changed the trans filter as well.

It might. New ATF is a tremendous cleanser. Black ATF usually means there was either fluid failure or severe clutch wear since the fluid was previously changed. Regardles of what caused the previous fluid to go black, there is undoubtedly residual dirt in the system that the new ATF is going to clean out. Such cleansing can cause tranny failure if a "chunk" of debris is disloged and blocks the oil flow.

Keep a close eye on the new fluid. If it starts getting dark, change it again in 1000 miles, and maybe again 1000 miles after that. I know this isn't cheap but two or three flushes is much cheaper than a rebuild.

GooD luck,

Don

^^^what Don said^^^

Fluid that's as dark as you say is either very burnt, or it's contaminated. If it's burnt, then something overheated it, either an internal issue or your driving habits: i.e. trailer towing through the mountains, doing lots of brake-stands, etc. If you're lucky, a couple of changes will clear out the burnt fluid and you'll be OK.

If it's contaminated, then something in your trans has ALREADY failed (clutch-pack friction material, most likely) and total failure is imminent...

Oh, it was burnt. You could smell it. I had to move the bucket outside becuase the smell was giving me a headache while I was working on it. Both my brothers had the car before I did and they were anything but gentle. And I kinda drive like I stole the damn thing. I don't beat it up, I just drive it hard. Is it too difficult to add a police trans cooler to the line? I saw one in the junkyard yesterday.

Be cautious about putting a salvaged trans cooler in your car. If the car was junked because the trans went bad, it might be full of crap. Ford has an in-line filter to be installed after trans failure to keep fragments from going back into the trans. You are supposed to flow test the cooler and lines before hooking them back up after a trans overhaul.

run some cleaner thru the lines, before installing the cooler, or in case of tranny replacement, you must clean the whole line system.
