With a 3.9L, maybe. It should have a 42re with a V6 or a 46 RE with a V8.
Not correctly. Needs to be a 46RE.
No, the Durango either has a 44re (never used in a 1500), a 46re with a different bell housing, or a 45rfe. None will work properly in a 2001 1500.
No.
Yes they are the same.

The 46re transmission is the same, but the torque converter is different for each engine.

The 5.2L was not available in 2003. Its last year was 2001.
