I used my 4-wheel drive one this year and I had a hard time going from 2-Wheel to 4 Wheel with the shifter. Seems like also my 4L has issues staying in place.

Anyone had any trouble shifting in and out of 4-Wheel drive?

You have to shift quickly and firmly going into 4WD. You can feel the lever notch into place but if you don't do it briskly, it may not engage properly.

To go into 4Lo, you have to push the lever straight down rather hard and pull all the way back. Can't have a drink in the cupholder in 4Lo.

Thanks for the information, will try what you said to try.
