M.B. Doc-
The hydraulic fluid was just changed and is at proper levels. I also had the fluid in the transfer case also replaced. Hydraulic fluid shows proper level in the bottle.
Could the mechanic have messed up with the transfer case fluid.
P.S. I mentioned that when I move the lever in to 'TEST MODE', the car drives like a dream. I was under the impression that that rules out a hydraulic problem..... but again, I am just parrotting what I've read in many threads on this site.
Any further thoughts? Thanks
