Without transmission, cars would be limited to one gear ratio. The gear ratio is selected so the car could travel at the desired speed. For example, if you want a top speed of 80 mph, then the gear ratio would be similar to third gear in most manual transmission cars.
Gears are generally used to either reverse the direction of rotation, increase or decrease the speed of rotation, or move rotational motion to a different axis. Car transmission uses gears to make more effective use of the engine’s torque and keep the engine operating at an appropriate speed.
Cars with manual transmission have engines connected through the clutch. Without this connection, the car would not be able to come to a complete stop unless you turn off the engine. Cars with an automatic transmission have no clutch that disconnects the transmission from the engine instead, they use a special device called a torque converter.
The automobile transmission is a crucial part in your vehicle. That’s why you must entrust your car transmission maintenance and repair only to reliable auto mechanics. Doing so will help you get back on the road worry-free. You may also get price quotes online or find transmission installers in your area. Transmissions come for both 4-wheel drive and all wheel drive applications. Most popular models are in stock for immediate availability and may come with a 3 year/100,000 mile warranty, which includes the parts and labor.
For fleets and heavy duty users, a full range of medium and heavy duty transmissions — 5 speeds up to 20 speeds — are offered. Heavy duty transfer cases are also available.
