Yes, I know the traditional position is to stick with Mobifluid 424. Until recently, Penrite did not list a compatible fluid. I just noticed they now list their semi-synth ATF MHP:

The cool thing is this is what I already use in the transmission, making touring spares easier.
Has anybody used this in their transfer case? I want to be "first to be second" here.
