4r44e is clunking hard, what can I replace it with?
The vehicle is a 1999 Ford Ranger. It is the 3.0, and from what I can gather it is the 4r44e. I've had the truck for about 2 years now. She has been great to me. This vehicle was my daily driver so that I could keep miles off my turbo fox body, but now it's my dd for my ls1. My gf had the truck for two days while I replaced a throw out bearing in her mustang. I took the truck back and didn't drive it for a day. Well I hop in it to head to classes and I noticed 2-1 (might be 3-2) shift clunks extremely hard all of a sudden. I checked the fluid, it's def burnt. It's brown, I feel as if thats the obvious sign of clutch packs being toast. I normally don't put addatives in my car's, but I bought some lucas bs, it didn't work at all. I had purchased fresh fluids, but at this point I feel if I flush it and the clutch packs are toast, the tranny is done for at that point.
So my question is, I have found a cheap low mile 4r55e. From my understanding this tranny belongs in the 4.0 rangers. All the specs seem to be about the same. The problem is no one is selling the tranny my truck has locally, so I was wondering if there was a chance that this would be a straight swap into my truck, or a swap with only minor mods to work?
