The 45RFE was originally used in the 1999 Jeep Cherokee.  In 2000 it also started to be used in the Dodge Durango and Dakota.

This is a computer controlled rear wheel drive overdrive transmission.

There are no bands in this transmission.  It's operation is very similar to the A604 and 42LE.

The bottom line is the cooler return line.
