2009 ford explorer 4x4 high
I drive a 2009 ford explorer. Yesterday I put my car in 4x4 high since the winter is coming. I usually have the car in 4x4 auto. I started the car and while it was in park pressed the 4x4 high button. As I was pulling out of the driveway the car seemed very sluggish at first. While I'm on the road it works just fine. Today as I was driving to school, I was pulling into a parking space and it was very sluggish like it was grinding or something of that sort. Is everything okay with the drive-terrain/transmission? I just want to make sure everything is working properly.
