Let me start off by saying I have a 00 Ranger XLT 4.0L 4x4. I have the 4R55E trans, but I can get a brand new 4R44E trans for free. It even has a 2.5yr unlimited mile warranty. There is 160,000 miles on my 4R55E now, and it is starting to slip, a little. I don't do any heavy towing or lifting. Just a daily driver, but I do use the 4x4 on heavy snow days. The 4R44E is from a '00 Ranger 3.0L 4x4.

1. Is it possible to just do an easy swap?
2. What are the downfalls of doing this swap?
3. Is there anything else I am not considering?

PS-> I am a noob, but I love the site. Lots of great info. I did a little searching before posting, just didn't find anything. Thanks for the help!
 
a trans from a 3.0 will not bolt up to a 4.0 motor, they have different bellhousing bolt patterns. if it was a trans from another 4.0 then it could possibly be done.
