How to fix automatic transmission that stays in low gear

November 5, 2021 by No Comments

In a car with a standard or manual transmission, the driver must manually shift into first gear, and then once the car starts rolling, the driver must manually shift to second, then third, and so on as it increases. the speed of the car.

Meanwhile, an automatic transmission allows the car to change gear ratios automatically to shift from first, second, third, and so on. Automatic transmission is possible thanks to the series of valves and switches that control the hydraulic pressure. Most cars on the market are now available with an automatic transmission.

If the automatic transmission has problems, you will notice that when accelerating from a stop, the transmission does not shift to the next higher gear. The car seems to crawl even though the engine speed increases. You can hear the engine screaming louder than usual, but the car isn’t really moving smoothly.

This is because if there is a fault in the transmission control system, the transmission remains 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 car’s speed reaches sixteen miles per hour. If the transmission does not shift, the engine speed will continue to 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 that 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 function properly. Transmission will not shift or shift will be delayed if vacuum hose is disconnected or blocked. Just highlight this to your auto mechanic if you are unsure whether your car is equipped with the transmission modulator.

Aside from the above, it is also possible that the problem with the transmission comes from a misaligned, disconnected, bent, or broken transmission shift selector connection. This means that the position indicated in the gear you are in does not match the actual gear of the transmission.

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 tips above can surely help you before you agree with the auto mechanic for any major transmission system repair.
