Are 46rh and 47rh parts interchangable? How do you find out for sure? If they are, all my upgraded parts from my 46 are going into a 47 swapped case! I want real, truthfull answers... damn transmission shop salesman deck heads!

 

For the most part, all of the 47 components are a step up from the 46.

What beefed-up parts from the 46 are you talking about?

Is it just the 47 case, or the entire trans?

 

i have a new foreward five pinion planetry, new output shaft, valve body kit, rear drum, gov. support, OD sprag and race. i have about two grand in the trans. i'd like to get out from underneath it. or use the parts to build a 47
