Around 54,000 the truck became hard to shift I brought it in to the dealer and was told the cause was my floor mats. I removed the floor mats and the truck still is a hassle to shift If I place it in neutral at a light it won't want to go back into first unless I run it threw the gears starting where ever it decides to let me. Sometimes it won't go into reverse unless I run it threw the gears to first then reverse
