Re: Gearboxes

461 has used toughbox minis in the drivetrain for 2014 and 2015. This year we used sonic shifters. We liked the toughbox minis since they were so simple to integrate into our sheet metal drivetrain (direct drive using the frame as the output plate). The sonic shifter worked well for us all season until we sheared the pin in the dog gear. We had been using the internals of a super shifter from '08 so the dog gear/roll pin was the older revision than the current model. I'd also recommend not running the shifter on 60 psi (we feel comfortable with 35 psi).

In regards to the "jerk" when shifting, you might experiment with ramping your motors and auto shifting for a smoother more efficient drive.
