Bad case of Tinkeritis!
cousin has a 91.5 dodge 250 4x4 that had an auto tranny in it til it blew up in a truck pull. now she is looking to either put the original back in or go to a new manual valve body trans. its only going to be a little over stock maybe injectors and some pump tuning but will be daily driven only so kinda interested in an OD trans.

figured i would ask around and see what all is involved to do a swap to say a 47RH trans and would it be worth it?

thanks

A manual valve body for a 727 only costs $200.

To swap to a 47RH you need a new converter, the transmission, and to get jiggy with the crossmember. I don't believe that you need to do anything to lines or linkages. You may need to get custom driveshafts made. The electronics on an RH can be operated with toggles.
 
The 727's were the 3-speeds that they stopped making in '91; non-overdriven.

The 4-speeds that they went to in '91.5 were basically 727's with overdrive, and have manual valve bodies available for around $400.
 
Same bellhousing, felexplate, line positions, shift linkage. Different converter, different mounts, probably need a custom or different drive shaft. Need to run a couple wires and switches.

You need a 47RH, RE's require custom stand-alone controllers. I think the years for the RH are 94 and 95.

Don't take any of that for gospel, but it's what I've heard. The only conversion I've ever done was a 727 to 518.
 
you'll need: 94/95 trans, engine adapter, flex plate, starter, modify driveshaft(s), modify crossmember, wire in switches/toggles for overdrive and torque converter lockup, etc. etc. etc.

In the whole process right now. Should be fun when it's done :)
