So, out in Leadville Colorado last week I got my 012 SR5 stuck by pulling off a snow covered road shoulder dropping the drivers side wheels off the hard pack. ATRAC tried its best but no go, it was high centered on the snow. Common mistake, got pulled out by a Tacoma within twenty minutes. Bt here's the transfer question. When shifting between 4H and 4L I couldn't get it to not grind, in all gears D,R & N. it even did it shifting back to park. I had my foot on the brake to stop any wheel motion, etc. owners manual says to shift to N, It still did it. This wasn't a slight grind, it was unnerving and needed force. Similar to shifting a unsycnronized tractor tranny. Any thoughts? Is also shifted hard between 2H and 4H. Truck has 5k on it.
