Handbook Transmissions
Handbook transmissions require a number of ancillary parts to facilitate gear adjustments. It’s typically managed by the clutch system, which disconnects the engine from the drivetrain to permit fast, easy gear adjustments. Most clutch programs use a single clutch disc or a collection of discs, and over time, these parts will put on.
