Re: AndyMark shifter Dog Gear screw problem - lower your pressures

Edit: The only thing is the shifters shift a lot more sluggishly at 45 psi.
James, how many times per match are you guys shifting? If I remember correctly, we usually shift once or twice a match at most - and we've got at least 15 matches worth of wear on our transmissions.

Does anyone know of a way to make the transmissions shift more smoothly and quickly at lower pressures? From what I've seen, our transmissions have a noticeable (1-2 second) lag when shifting between high and low gear below 50psi.
