Transmission fit in a truck?

Okay so I have a 98 Ford ranger 4.0 4x4. And the transmission went out. And I found a couple transmissions. And I'm wondering if they will fit. I think they will but want to make sure. The trannys. Are from a 2002 ranger 4.0 4x4. And the other from I think 01 4.0 4x4. If they fit what all will I need to do different or will they just bolt up with no problem thank you

You're good 97-04 from the same engine. If it's full and won't move then don't bother with the adjustments or trying to do a fluid/filter change it won't work

A good salvage yard could give you a list of what years will fit your explorer. During those years the 4.0 changed from a very dependable, long lasting, high mileage push rod engine to that stupid ohc morphadyte, concoction, timing chain eating engine. Not sure if the bell housing changed our not. I doubt it would but don't know. The '00 and'01 are the same. Don't trash it yet. There are two band adjustments on the side of the tranny. Try tightening those first. If you pull the pan, look for a blown out gasket around the overdrive servo. It will make a soft shift into overdrive. You may also get ratio error codes on the band adjustments and the servo cap gasket. It is basically squarish with 4 bolts in each corner. Be very careful what fluid you use. Check your manual. Mercon V I think…
