Mazda Transmission

In general, the transmission performs a speed-power conversion or gear reduction to a higher torque. It may provide several diverse speed-power ratios or known as “speeds” or “gears” and probably many variable speeds in reverse direction. Some larger vehicles such as trucks and tractors are usually equipped with a dozen or more forward “gears” which differ from a crawling speed to a maximum speed at low torque wherein the only torque required are the small additional force needed to surmount the continuous friction and all other road losses such as climbing a grade. In order to overcome a grade, if the torque is insufficient at a higher rotational speed, the gearbox is shifted into a lower gear to allow more power. This is needed when starting to accelerate the vehicle into the desired speed. This allows the gear ratio between the engine and the wheels to adjust in relation to the vehicle’s speed, as it speeds up or slows down.

Normally, Mazda transmission and gears are enclosed in a cast iron case, usually aluminum, with three shafts such as the mainshaft, countershaft, and the idler shaft. The mainshaft extends at the outer case on both directions while the input shaft goes toward the engine and the output shaft to the rear axle. The main bearings suspend the shaft and are divided towards the input end. At the point of division, the shaft is held together via a pilot bearing. The mainshaft holds the gears and the clutch, where the gears can spin freely in relation to the mainshaft, except when the clutch is engaged. Transmissions include manual, automatic or semiautomatic transmission system.

The transmission mechanism in your vehicle should be regularly checked to avoid serious problems as well as to ensure your safety. Some signs to watch out for include transmission overheating, gear damage, band damage, and oil burnout or loss/poor power. All these problems require immediate action and if you want to ensure its condition, have it thoroughly inspected by a qualified service technician for best results. If a replacement is necessary, you can always easily acquire it on various automotive stores. For your Mazda model, you can find several options of Mazda auto parts and Mazda OEM parts at leading automotive stores.
