You might have somehow blown 2nd. I dont know your driving habits, but continuous hard driving will do that,it is not the shift linkage going by what youve described, Sounds like there is no teeth left on sencond gear, it may have not been set up properly, and it was gradually wearing down the gear as you drove, second is a gear you dont use much, so it took a while for that to happen. first third and overdrive are most common, If Im right, You may want to get all the gears checked, as they may be wearing down slowly as well, then soon youll have no drive left,
