Change transfer case fluid M923 A2

[jmarch58]

Hey guys I want to put new oil in the transfer case and can't find much help in the tm. M923 a2 is the truck I'm working on. I found the drain plug easy enough but can't find where to fill it from. Also want to use the best fluids so any advice would be great

Look in the LUBRICATION ORDER LO 9-2320-272-12 http://www.steelsoldiers.com/showthread.php?108874-Transfer-case-fluid-change-in-a-M923a1

90w-140? Will that work or is out too heavy an oil also where is the fill port or do I need to pump in through the drain

The fill hole is just above the drain hole. 90w-140 will work, but the lube order wants 80w-90.
I use 90w140 here in AZ.

Well thanks for the help guys just took her for a spin feels a million times better after fixing the wire for the button and changing the transfer fluids. Moved the wires on the high low shifter so they don't rub the parking brake box ever time move it.
