Default Swap an '05 5 Speed Manual to an'02 ZR2 Auto both 4x4

Hi All. Hoping to get some insight into what's involved in transplanting the five speed manual transmission in my tired '05 LS Jimmy to a much fresher '02 ZR2 Blazer. Bought the '02 Blazer with a blown automatic transmission for parts, then discovered it was in overall better shape than my '05 Jimmy. It even runs better, and has lower mileage. I'm fairly certain all the parts are directly interchangeable, just not sure if the computers and or electronics are the same, and what other challenges I may encounter during this task. I've always preferred a manual over an auto, and I need to do the job myself ( with some help from my friends ) to make it feasible.. so I seek your wisdom and advice to aid me in my endeavor. In addition to the transmission swap, the front driveshaft on the '02 was removed due to the need for a replacement actuator, which came with it when I purchased the truck, however it was never installed. I know the 4WD system in the '05 is tip top, so once again, if something turns out bad with the '02's 4WD system, are the parts from the '05 a direct replacement? I must note that the ZR2 has an auto 4x4 option, whereas my Jimmy does not.
So I will now say thank you to you all in advance for any, and all input you can share.
