Problems changing transfer case fluid
I am in the midst of trying to change the transfer case fluid on my 2006 5.7L Jeep Commander. It looks like a quart came out but I am only able to put back in a few pumps before it pours back out. I repositioned the hose a few times but I keep having the same problem.
As anyone had this problem? It seems like there is something blocking the fill plug hole and there is just a small slot for fluid to flow into the transfer case. Is there some trick to this? Even though I am pumping very slow am I pumping too fast? or am I supposed to put the transfer case in any particular position to fill it? I've never had a diff or transfer case be this difficult to fill. I have even jacked up the rear end of the car to help, but that does not work either.
Thanks in advance.
