How often do you grind gears.... Realistically

Never. I still occasionally forget I pre selected a split on my 13 spd. The fix has been not pre selecting till it’s time.

 

When I'm tired from a long day.
Start pushing the clutch pedal in too far and I think it engages the clutch brake.
Depends on the truck.
Anyways, the whole spinny spinny in the tranny slows down and messes up the synchronicity.

 

Well those are synchronized gears, to be fair.

 

I personally think some transmissions are easier than others to shift without grinding. I have been driving for over 4 years and I scratch gears quite a bit yet. To believe there’s super truckers that never even scratch is too much for me to believe. Now that loud harsh grinding shouldn’t happen.
