OK, this has happen 3 times so far. I get in the truck first thing in the morning, take off to go to work. My truck is stuck in 3rd gear. It is slow to take of. It will not shift into D or overdrive. After about 20miles I stop cut off the truck turn it back on and it is fine. It makes no sense. It has happen just in the past wk. Does anyone know or have had this problem.
