In a car with a standard or manual transmission, the driver must manually shift into first gear and then, after the car starts rolling, manually shift into second, then third, and so on as speed increases. of the automobile.
Meanwhile, an automatic transmission allows the car to automatically change gear ratios to shift from first, second, third, etc. The automatic change is possible thanks to the series of valves and switches that control the hydraulic pressure. Most of the cars on the market are now available with an automatic transmission.
If the automatic transmission has a problem, you will notice that when you accelerate from a stop, the transmission does not shift up to the next higher gear. The car seems to be dragging even though the engine speed increases. You can hear the engine scream louder than usual, but the car doesn’t really move smoothly.
This is because if there is a fault in the transmission control system, the transmission stays in low gear and the car moves faster than it should in low or first gear, so it can be hear a loud roar from the engine.
If you put the automatic transmission selector in the “Drive” position, the normal shift from first to second gear occurs when the speed of the car reaches sixteen miles per hour. If the transmission doesn’t shift, the engine speed will still increase, but the car will still not reach its normal speed.
The first thing to do is check the transmission fluid level. Refill with the correct type of fluid if you find the fluid level is low. When checking the level, also check the color of the transmission fluid on the dipstick. Light green or red means there is no major problem with the transmission system, but if the color is dark brown or black, the car will need major transmission repairs.
Some cars come with an additional device installed in the transmission known as a modulator where it will create an excellent vacuum for the transmission to work properly. The transmission will not shift or there will be a shift delay if the vacuum hose is disconnected or blocked. Just highlight it to your auto mechanic if you are not sure if your car is equipped with the transmission modulator.
In addition to the above, it is also possible that the problem with the transmission stems from a misaligned, disconnected, bent, or broken transmission shift selector linkage. This means that the indicated position in the gear you are in does not match the actual transmission gear.
In some cars, the shift point, which is the exact speed at which the transmission shifts, is controlled by a cable. The transmission will not shift properly if the cable is disconnected or broken.
The above tips can surely help you before agreeing with the auto mechanic for any major repair on the drive system.
