Another provision for the clutch related to the increased engine speeds. To make sure that the integrity of the clutch cover was maintained under high-speed operations, additional material was added for strength.

Manual Transmission Upgrades

In keeping with the sporting nature of the Z06, an automatic transmission will be not be available. The six-speed manual transmission has a new set of ratios, for a more aggressive launch and acceleration through the gears:

More Direct, Positive Shifter Feel

The shifter bushings have been eliminated to give the manual six-speed transmission in the Z06 a more solid, precise feel. These rubber inserts have been eliminated to balance the combination of isolation and positive shift feel toward performance shifts.

Transmission Temperature Sensor

A transmission temperature sensor is included safeguarding the transmission from extreme high thermal stresses. When the transmission reaches 325° Fahrenheit, the Driver Information Center (DIC) indicates a "trans over temp" message to let the driver know that the transmission may get damaged unless the speed is reduced.

Driveshaft Revisions

Due to the increased torque output of the LS6, several changes have been made to the driveshaft of the Z06 Corvette:

• Increased torque capacity of the flexible rubber drive couplings

• Revised rubber coupling material specifications to a higher temperature resistant compound to improve heat-aging performance

• Increased drive coupling fastener size from M10 to M12 bolts

• Revised the driveshaft tube material from the metal-matrix composite (MMC) to aluminum alloy 6061, and the driveshaft diameter from 55 mm to 63 mm, an increase of almost thirteen percent. These changes were made necessary by the increased output of the LS6 engine
