Is there a direct swap 2 speed transfer case that will replace an 4L70 from an 07 TBSS maybe from a 5.3 Trailblazer? Will it use the exact same yokes front and rear, any tuning or extras involved other than mounting the 2WD/4WD/4Lo selector I need to grab from the donor vehicle?

I’m close to doing this....using a MP3023 GM tcase out of a 07-13 vortec max 1500 truck is the winner. These trucks also have the exact same 4L70E trans as the TBSS. The tcase is completely electronically controlled and also is an aluminum housing...meaning not crazy heavy. Will post an update when done.

Would be awesome to be able to go back and forth like a normal SUV/Truck....who knows maybe get a few MPG's out of it.
