If my hubs are locked and I am in 2Hi does it hurt to let off the gas and put it in 4Hi? I have a C-6. I do it often and it doesn't seem pissed. Gracias

Hell no
I have had both a C6 and a NP435. Both shift easily in and out of 4hi and 2hi at speed as high as 60 mph. (as far as i have tested it). I just let off the gas.
I can even go from 4hi to 4low and back with speeds under 10 mph.

Sounds good. Why don't you buy his old 460?? I think it's a good deal, I'm not sure what he's asking though. Are you leaving both gearsets stock in those cases? What will be the final ratio/combos?
