Also its listed as a direct replacement to 52118780AD

I just want to be sure before I order it.

 

Every way I search it there, it pulls up that part, and says it will work on 2500, but no on 1500. The tranny is the same on 1500 and 2500, o it should fit. The 46RE did not change.

 

I got it on today and it fits. Thanks.
