Fellas - I understand the S42 is rated for 420 ft/lbs and the S47 is rated for 470 ft/lbs, but does anyone know what the internal differences are? Are all internal parts interchangeable? Did a search and didn't find the info that I was looking for.
Reason I ask - I just disassembled the 1996 S47 4x4 trans that I'm going to use to convert my '87 F350 CC DRW truck to 4x4. I have the original S47 2WD trans from the truck, too, and I'm wondering what S42 parts I can swap in if they look better than the S47 parts - case, countershaft, mainshaft, etc.
On a related note, does anyone know what components were changed to get the torque rating from 420 ft/lbs to 470 ft lbs?
Thanks!
Scott
