So I've been keeping an eye out for the automatic overdrive transmission over the years. Recently a local ad popped up for a unit advertised as 46RH including an ATP rebuild-kit.

I took a look at it, it has the 3 pin overdrive connector which is telling me this is a lock-up unit.

The following is stamped on the side of the pan: PK5211916:23552105, where the ":" is either some sort of a separator character or just an garbled character.

Anyways, looking around I could not find anything on Google (or here) that mapped to the PK5211916 number. However, my archived copy of the 2009-2010 Mopar Reman Parts catalog shows PK52119160 transmission as the unit for 1994-95 Truck, BR Body 4x4, 8.0L and is identified as a 47RH.

Sooo....any other way for me to tell whether this is a 46RH or 47RH just by looking at the trans or the input shaft, sensors, etc?

Thanks!
