Transmission interchange/swap?

The automatic transmission used in the 2001 Explorer XLT is the 5R55E, which was also used in several other Ford vehicles, including the Ford Ranger, Mercury Mountaineer, and Mazda B-Series pickups. However, it is important to note that even within these vehicles, there may be differences in the transmission depending on the year, engine, and other factors. I would check the electrical connector to make sure they are the same and the output shaft.
