It seems like the "gate" has moved in my shifter. It started acting like there was a detent for first gear like the one for reverse; this started about two days ago. Today, it is near impossible to force the lever far enough to the left to get it in first. However, if I put it in reverse and then go back to first, all is well until the next time; it's not the gears. Should my first attack be at the shift tower lever mechanism or the at the transmission linkage end? Any secrets?
