Automatic & Standard Transmissions in Cars

Automatic and standard (manual) transmissions. It was not always this easy to drive a vehicle. At one point in time the only transmissions available were standard transmissions with a clutch and shift. At some point in time - to make driving cars and trucks more accessible to the full general public automatic transmission were invented to share the load on the road.

Historically for many years both engineers and inventors searched for a way to make gear shifting easier. The introduction of synchronizing devices such as the "synchromesh" unit for manual transmissions was one such device on the road to discovery. This device made it virtually impossible to clash gears when shifting a manual (standard) type of transmission. However the driver must operate a clutch to interrupt the flow of power while moving a lever to shift the gears from one power transmitting position to another.

Over the years, automatic devices which serve to eliminate manual gear shifting were developed. Primary among these developments is the now ubiquitous "automatic transmission" or simply the "automatic". These change the gear ratios through the transmission semi-automatically in accordance with car, truck or Sports Utility vehicle engine speed and the driver's selection or selections.

With an automatic transmission, the power follow is not interrupted not even momentarily during a gear ratio change. Ratio changes or "shifts" are achieved by use of hydraulically actuated clutches and "bands". If the gear ratio happens to made what is considered by passengers in the vehicle , too abruptly or soon , then the passenger or passengers in the vehicle will be jarred and the transmission will wear and wear out much more quickly than would be expected otherwise overall. On the other side of the roadway if the shift is made too softly, then the friction faces in the clutches and bands will be destroyed by wear autel maxisys elite price. Overall to eliminate these problems, control of clutches and bands must be precise, even more than precise. Automatic transmissions perform their functions automatically , that does mean as many motorists and auto owners somehow believe that they are totally maintenance free and are without a maintenance schedule that must be followed and adhered to. In the owner's manual, in the glove box of your vehicle - the maintenance manual from the manufacturer of your car, truck or van will have a recommended service schedule Autel MaxiDiag MD802. Included in this will be a recommended service schedule for your automatic transmission. Follow this to the letter for long transmission life and lifetimes. If your service schedule fits into the severe driving classification ( commercial vehicles , taxis , police cars and the like that have lots of stop and go driving , extra cold weather driving etc) , then follow the even more rigorous automatic transmission maintenance schedule recommended. You will rewarded with many more miles and years of trouble free automatic transmission performance overall. Chief among these recommendations is regular changes and flushes of your automatic transmission hydraulic fluids. Two years between intervals is the recommended time frame generally.

How do automatic transmissions work - as opposed to the older "manual "or standard types? Instead of using a foot operated clutch, as in the standard manual type of auto transmission, a fluid coupling connects the engine with the power train. Engine power is transmitted through a fluid or oil, and it allows the transmission to be gear at engine idle. Simply put the velocity of the fluid in the fluid coupling is too low at idle speeds to propel the car forward.
