Sometimes, the channels get clogged with dirt, which affects the clutch’s functioning, ultimately leading to car jerks. Malfunctioning Valve BodyĪlso known as the hydraulic valve, the valve body has many channels through which the transmission fluid runs under hydraulic pressure to compress or expand the clutches. This brings the dirt from the bottom to rise and clogs other transmission parts like the radiator, hydraulic plate, and solenoids. Oil fluid is generally extracted without replacing the oil filter or flushing the box tray. However, the cooler tends to get hot as its performance decreases because of how old transmission fluid is replaced. Ideally, a transmission oil cooler should cool the transmission fluid. If the plates have major wear, these shocks or twitching may intensify.Īnd if the plates are beyond repair, your gear may appear too stubborn to shift. ![]() Besides the jerks, the transmission fluid levels might also drop drastically or lose their properties. You may feel shocks when changing gears if the plates wear out. The friction plates in automatic transmission vehicles act as a clutch when changing gears. It usually means that your fluid isn’t being managed well. You can suspect a torque issue if you notice a slipping transmission. Malfunctioning Torque ConverterĪ bad torque converter shows almost the same signs as a slipping gear.Ī torque converter connects the engine to the car transmission. This is why it’s essential to get regular transmission service and use high-quality ATF oil according to the manufacturer’s instructions. That’s why your car jerks when you press the brake pedal and shift gears. ![]() This affects the functioning of friction discs.Īs a result, the discs won’t be able to stop at the right time and won’t have the necessary force to slip again. It’ll then clog the automatic transmission oil filter and limit the transmission fluid supply. With time and use, metal chips may form in some of your transmission parts. So if your transmission fluid level is low, your transmission light may pop on, and it’s best to top it as early as possible. Low transmission fluid levels may lead to low pressure and result in transmission trouble, like a hard-shifting automatic transmission. Transmission fluid lubricates and provides the hydraulic pressure needed to move the clutches and bands for the shifts in automatic transmissions. If your transmission fluid becomes old, it’ll reduce the fluid’s lubrication and friction-modifying properties - ultimately leading to transmission shifting issues. These aren’t the only transmission fluid issues affecting your car. Using the wrong transmission fluid may result in some hard car jerks, especially at high speed. That’s why manufacturers recommend using a certain transmission fluid type to avoid any transmission trouble. Your transmission is built with materials compatible with a specific transmission fluid. In such cases, it’s best to get an expert to check out the transmission. ![]() But over time, these bands and clutches may smoothen out, making it difficult to hold things together. Transmission bands and clutches help you change your gears swiftly. Now, let’s check out some causes behind those car jerks: 13 Reasons Why Your Car’s Transmission Jerksįrom a clogged catalytic converter to a worn-out transmission and low transmission fluid, there are many reasons for your car to jerk. However, if your car has a computer-controlled transmission, erratic gear shifts or any other transmission problem can also happen due to a bad sensor or shift solenoid.
