Np 246 transfer case question
My 2006 z71 suburban original transfer case went out. A local mechanic told me all np-246 cases are the same and I bought a nice looking used one from him.
but found that the control motor plug doesn’t fit. My suburban harness has the 8 pin while the new-used transfer case has a 4 pin.
I thought I’d swap control motors but found out the shifting shaft into the case is different.
Can I just swap the gear in the control motor to fit the new shaft??
This is the original in my 06 suburban.
This is the shift style on the used transfer case I bought.
I can’t seem to change gears manually on the oblong shaft case. It feels very “springy”. Should I be able to shift it to at least move the car a few miles by manually shifting? Or does it require constant pressure from the electric
motor to hold the shaft in position??
thanks for any info!!

Why not take it back and get the correct unit?

I hope OP changes the lubricant on it. Axles, TC's and auto/man transmissions are not changed as often as they should be, then the owner spends $2000 bucks or more to swap it out. Go figure!
