I am looking for a way to "tighten-up" the free-play of the shifter when in the neutral position. (without replacing all the shifter parts, if not needed)The movement is only slight, but definitely more than new. has anyone else noticed the "free-play" increasing with time?. any tips? The car has 30K mi. I have looked in the helms manual, it looks simple enough. I just don't know what part to replace or if it all just gets worn over time. any info would be appreciated
