I spent about $2300 a few years ago to build a 46re for a '98 5.9 ZJ. It is basically 47re diesel tranny internals shoved in the 46re case. I would assume you can do the same thing with the rh's.

The cases are the same size. The 47RH transmission was created by upgrading the 46RH transmission and the overdrive unit. Base transmission revisions were:
Input shaft enlarged 0.070-inches at the torque converter clutch oil feed hole
Torque converter clutch oil feed hole shot-peened inside
Pressure angle on spline between the intermediate shaft and the front planetary gear unit changed from 37.5 degrees to 30 degrees
Fifth pinion added to the front planetary gear carrier
Reverse band widened and changed from single to double wrapped configuration
Reverse servo unit revised
Case casting and machining redesigned to accommodate internal changes noted above
Overdrive unit revisions included the following:
Ninth disc added to overdrive direct drive clutch
Output shaft governor shaft cross hole shot peened to increase fatigue life
Output shaft selective annealing process revised to allow governor shaft cross hole to remain hard
Governor drive key changed from semi-circular "Woodruff" to a 1/ 4-inch square to reduce stress on the shaft
