The initial condition that caused concern: hard shifting. To move the shifter between any two positions required higher than normal force. This condition alleviated instantly after approximately one month. The force required to move the shifter became normal again. No sounds or other unusual things were observed. The only differences from before the condition until the current condition is the transmission will not go into park, and will only start in neutral. Current condition: the truck will not shift into park. When attempting to put the vehicle into park, the shifter will move enough to allow removal of the key, however, the transmission will not engage park. Because of this, the vehicle is always free to roll. The only way to keep the vehicle from moving while attempting to park is to use the emergency brake. This vehicle is currently both highly inconvenient to drive and highly unsafe. Items: - I have found blogs referencing this issue back to 2004. I know this experience is not unique to this vehicle. .

Four wheel drive will not engage. The lights on the dash just flash and eventually return to 2hi. Nothing works - shifting to neutral, slow roll, dead stop. Nothing. I cycle the 4wd once a week. Worked last week and not this week. Last time 4wd was actually used was in January 2009.
