Performance Clutches Clutch Disc Kits for manual transmission equipped performance Chevrolet Cobalt and Cobalt SS 2005-2009.
The basic arrangement of shift quadrants is referred to as an H Pattern. The shift pattern is usually printed on the shift knob or located somewhere on the center console. Depending on transmission design R or reverse may be located at the upper and lower corners of the shift pattern. Performance shift patterns are almost always intuitive because they start at the upper left and works top to bottom, left to right with reverse toward the rear of the car.
Manual transmission clutch disc designs are based on friction clutch disc pressed tight up against a flywheel using pressure plates containing springs which allow the car to change gears effortless. Without a properly working performance clutch disc changing gears in a clutch disc equipped manual transmission car would be very difficult but not impossible. Manual transmission performance equipped cars offer better fuel economy than automatic transmission equipped cars.
Spring pressure is released when the clutch disc pedal depressed allowing the clutch disc plate to spin freely which allow shifting the gears up or down. Spring pressure is positive when the clutch pedal is release causing the car to move forward.
The clutch is operated by the left-most pedal using either hydraulics or a cable. Most performance manual transmission cars today operate on the principle of hydraulics. Manual transmissions are also referred to as a stick shift or standard transmission. Current performance manual transmissions are available as 4, 5 or 6 speed versions with a gear stick that is connected by linkage to the transmission. There are a limited number of high performance vehicles in production that have performance 7 speed transmissions. Each performance version also has at least one reverse gear. Manual transmissions are synchronized meaning that the transmission gears are always in mesh and rotating which allow you to move up or down the gears with ease and smoothness without stopping the car. Reverse gear is not usually synchronized and requires the car to come to a completely stop before engaging the reverse gear. Have you ever missed and heard the grinding of the gears.
In rear wheel drive cars, the transmissions input and output shafts are on the same line. In front-wheel-drive cars like the Chevy Cobalt the clutch disc driven manual transmissions are designed with an integral final drive and differential and they have an input shaft and a counter shaft.
