Just started yesterday on a fishing trip. Started by popping out of 1st, then it was 1st and 3rd. About 1/2 way home I had to hold it in all gears, if it went into gear. From what I see online and you-tube it looks like the shifter seat and socket and is an easy fix. Anyone with experience on this have any tricks or cautions I should worry about ? The only warning I hear at all was to not use A/M as they don't hold up or are made of rubber and to change out the fluid after to remove any debris. The vid's I watched mostly show a real sloppy shifter. Mine is very tight and has very little throw. Sound like my problem ?
