We had a bit of snow the other week, I drove it to the gas station to fill up my kerosene jug in FULL TIME. When my wife got in it the next day, she said it wouldn't go back into 2WD. At the time, I just assumed maybe it got quite a bit of snow packed under there and got stuck. Well, the snow has melted and I got under there to check it out. Nothing looks out of the norm, no broken brackets or cables. It stays in PART TIME, and still moves to all the other 4WD options, but will not go into 2WD. When you pull it back into what should be neutral, its shows 4 Low, and it won't go back any farther. I did a search, but nothing came up, no matter how I worded the problem. Has anybody ran into this problem? Is this something that I can repair(I do 99% of my mechanical repairs), or will this require a trip to a trans shop? BTW, its a 04 Limited.
