Only transmission that would fit is a zf6 I'm going to be swapping in the next 3 weeks or so. From the research I have done you will need transmission, clutch, flywheel, clutch master and slave assembly, clutch pedal, transmission hump, transmission crossmember, manual trans ECM or have yours re flashed, trans wiring harness, clutch pedal sensor and possibly wiring. The only thing I am still trying to figure out is if the transfer case will bolt up. The 7.3 auto to manual requires a different input but I read that both 6.0 trans have a 34 spline output. Hope someone can confirm this for both of us.
