maybe....I asked my dealer to check the quick shift sensor at my first service because i thought it was a bit lumpy, he told me there wasnt really any adjustments possible.
a 1000k later and me learning how to use it better it smoothed up on its own.
If the service manual says there is a check to be made i guess there must be?
Maybe its just a check to see its still tightly fastened?
I was not doubting you, I was just wondering what the dealer actually does?
