I would like to service the transmission and transfer case on my jeep. The transmission is the Werner T 5 speed and the transfer case is Dana 300. One manuel I have says the transmission takes Dextron II ATF and the Transfer case uses 90 wt. gear oil. However in the same paragraph the book says to use the same fluid is both. Sounded contradicting, dont know. What fluid or fluids do I need to use? Thanks for the help.
