No. We thought that at first. But is not the case. Sometimes it will
release perfectly smooth and other times not, even when on flat terrain.
It also seems to happen most during the heat of the day. It just happened
this last Saturday. We moved the truck in the early A.M., but when we went
to move it again around 4, again at 8 & 9P.M. we couldn't get it to shift.
But, we waited until almost 11P.M. when it was cooler and lo & behold, it
shifted very easily.
