Driving to work this morning, nothing out of the ordinary occurred. Rather suddenly, no forward momentum when it's in drive. In 2nd it will go forward but not much, it drives fine in 1st gear. I drove on the grass at 5mph to the exit ramp and am sitting here contemplating what to do. I've never let a dealer or other mechanic touch my nuts and bolts but I don't have a lift and don't think I could drop the transmission and T-Case myself in the driveway. I am dreading the thought of a dealer or mechanic but damn, doesn't look like I have much choice. Call USAA towing?
