Hey guys, so I made the mistake of leaving 4wd hi engaged while changing out my automatic transfer case fluid. My transfer case was noisy before I changed the fluid so I just assumed nobody had changed out the fluid recently. So, I changed the fluid with the oem recommended Autotrak II and took it for a test drive. The 4wd will not properly engage and when I got back I had to top off the tcase again. I can hear the encoder motor working when I press the 4hi button and 4wd will engage atleast to some degree i.e. the front diff engages and I can hear the shifter. However, the 4hi button and 4low button just keep flashing when I try to engage each and my dash reads "Service 4wd." My question is: am I screwed? or do I just keep trying to engage 4wd to let the new oil work its way around the case. Isay that cuz my friend had a similar problem in his f150 but eventually it went away.
