46RH rebuild?

I could tell right away upon putting the junkyard trans in, that I was missing the effects of that shift kit that it didn't have that the original one did. I'm rebuilding that original one now.
It went 314k I put the last 100k+ of that on it, so I know it has good "bones".
That Durango pulls my camper easier than the 4.7 in my 12 1/2 ton. (This Durango has a 360 mag)
