WHAT IS POWER SHIFTING?

Power shifting (also known as; full-throttle shifting, flat-shifting, or speed shifting)is a method of shifting used with manual transmissions to reduce the time where the driving wheels are not powered. Unlike a normal gearchange, in a powershift the driver does not let off the accelerator.  The clutch is briefly depressed while the shift lever is rapidly shifted into a higher gear, keeping the engine in its power band. This helps the car...

WHY DOES MANUAL TRANSMISSION CAR MAKE A LOUD WHIRRING NOISE IN REVERSE?

WHY DOES MANUAL TRANSMISSION CAR MAKE A LOUD WHIRRING NOISE IN REVERSE? Manual transmissions use mostly helical gears, but reverse is a special situation that requires a different type of gear - a spur gear. The gears that make up the forward gear ratios are all helical gears. The teeth on helical gears are cut at an angle to the face of the gear. When two teeth on a helical gear system engage, the contact starts at one end of the tooth and gradually...

HOW THE POWER(rack and pinion) STEERING WORKS?

The components of the power steering consist of: • Power steering pump •Power steering fluid •Speed sensor •Steering rack •Steering wheel The POWER STEERING PUMP  It is a rotary pump driven by a belt from the main pulley of the engine at roughly twice engine speed. This pump is designed to circulate POWER STEERING FLUID through the SPEED SENSOR and at very high pressure from the pump to the STEERING RACK. STEERING WHEEL movements cause...
