We got a pretty good snow for Dallas last night so I got to go out and play. I have never really used the 4wd on pavement being in Texas. Always out off the pavement and have never noticed this. Last night a couple times when I needed to shift into reverse the shift lever would stop at around the R but before it engaged. It went when I gave it more of a shove but still ahve never experienced the blockage feeeling. I know on one of these times I was in a parking lots doing donuts and had it in 2wd. Any ideas? Sure was nice how the taco with BFG AT's did in the snow, felt unstoppable. But again this was 6" of fresh snow in Texas.
