In addition, downshifting at the right time provides better acceleration when you desire to resume speed. Downshift progressively. Do not skip gears to avoid overspeeding the engine and clutch. WARNING! Do not downshift for additional engine braking on a slippery surface. The drive wheels could lose their grip, and the vehicle could skid. CAUTION! When descending a hill, be very careful to downshift one gear at a time to prevent overspeeding the engine which can cause valve damage, and/or clutch disc damage, even if the clutch pedal is pressed. 5
