Today, I was dragging my dump trailer out of a sloped/muddy area, so I popped it into 4LO. I then needed to get out of 4LO, but it was stuck in 4LO. It took about 30 minutes of randomly driving forward, driving backward, switching between 4LO/4HIGH, coasting in Neutral and restarting to pop it back out. It finally popped out of 4LO when I was slowly coasting backward down an slight incline (in Drive) and the "hill hold"feature (the automatic brake activation that keeps the truck from rolling backward when you transition from foot-on-the-brake to foot-on-the-gas) activated. I'm not sure if the "hill hold" had anything beneficial to contribute to popping it out of 4LO, but that is what was going on.
I'm hesitant to try 4LO again as this is my only vehicle and it would be a bummer if it got stuck again.
Aside from regularly exercising 4LO, is there anything I can do to increase the chance that 4LO will work smoothly?
It was around 50F and the truck had been sitting overnight. Perhaps I should try again when the truck has been driven for a while and is warm.
I also tried to lock the center diff when I initially went into 4LO, but that just blinked. I don't think it ever locked.
