1st Gen G56 Swap
Well today I pulled the trigger on a '07 6.7 4x4 zero mile take out G56 trans. This one should be the AE with the .74 6th gear od. I will be swapping it for my 5spd Getrag and selling my Getrag. I hopefully will be using Southbends fe 13" clutch set up, that I already have. I hope that I just have to change the disk for a 1 3/8" input shaft. I heard the G56s input shaft is longer then a getrag5spd, longer then a NV4500 and NV5600 so I imagine I may need to source a G56 to engine adapter ..any one have asource?..also I think, I need to use a 3rd gen G56 starter any one know?... I believe the G56 has 29 spline output so my 205 should mate up ...I'll have to play with it I'm sure. I do plan on twin sticking my NP205 at the same time too..so it should be interesting. I will be doing a PTO and I'm leaning on doing a direct mount hydraulic pump to provide pressure to run my dump hoist..I'm debating fabbing a central hydraulic system..ie a 4 circuit system hoist, snow plow, and one hydraulic port and return at each end of the truck for a hydraulic winch or what ever...
I plan to document it for you guys and keep a thread going.. I hope it works out . I have heard of at least 2 maye 3 that have done the swap in 2nd gens so it shouldn't be too much different in a first gen.
Wish me luck.. does any one know of any one doing this swap before me? Southbend says they think I'd be the guinea pig ????! 
Thanks
Deo
