Park (P): This place disengages the transmission with the motor (as Using the neutral placement), and also a parking pawl mechanically locks the output shaft of the transmission. This prevents the driven wheels from rotating to forestall the auto from going.

The transmission operates rapidly and easily. Within an automatic motor vehicle, drivers don’t require added effort to shift the transmission because know-how will it for them.
Pada awal transmisi untuk auto terdapat sentakan yang agak kuat (contoh dari N ke D atau dari P ke D )
In addition to checking auto velocity and throttle placement, the transmission controller can keep an eye on the engine speed, Should the brake pedal is remaining pressed, and perhaps the anti-lock braking method.
The final Motors Hydra-Matic became the initial mass-generated automatic transmission following its introduction in 1939 (1940 model yr). Readily available as an option in vehicles including the Oldsmobile Series 60 and Cadillac Sixty Distinctive, the Hydra-Matic mixed a fluid coupling with 3 hydraulically managed planetary gearsets to supply 4 ahead speeds furthermore reverse. The transmission was sensitive to engine throttle situation and highway velocity, creating absolutely automatic up- and down-shifting that diverse In accordance with running ailments. Options of the Hydra-Matic integrated a wide unfold of ratios (making it possible for both equally fantastic acceleration in to start with equipment and cruising at small motor velocity in major equipment) as well as fluid coupling dealing with merely a part of the engine's torque in the very best two gears (escalating fuel economic system in People gears, much like a lock-up torque converter).
Bayangkan kalau pemandu terkejut sebab lampu trafic mild dah hijau lama & kereta belakang dah hon2 je. Tertekan pedal minyak dulu baru masuk equipment. Jawabnya, equipment anda boleh rosak atau
