Common Causes of Transmission Failure and How to Avoid Them

Your vehicle’s transmission is one of its most important components. Without a functioning transmission, your car won’t be able to drive anywhere. Even having low or no transmission fluid can cause irreparable damage to your car’s transmission.

You must know the signs of transmission failure before the problem gets worse. Otherwise, you might have to spend money on costly repairs or purchase a new car if you don’t deal with a faulty transmission right away.

This guide will discuss the most common causes of a transmission problem.

Low or Leaking Transmission Fluid

As we mentioned earlier, transmission fluid leaks can be hazardous for your car. Transmission fluid ensures your car runs smoothly. The fluid does the following for gears in your transmission:

  • Lubricates
  • Cools
  • Cleans

Transmission fluid can typically last over 50,000 miles in newer cars. However, if you have an old transmission, you might need to monitor your fluid levels more often. Your transmission can overheat if fluid levels get below a certain amount, causing transmission failure and major damage.

On many cars, your mechanic can monitor your car’s transmission fluid levels each time you bring in your car for an oil change. You should also check all your fluid levels each time you fill your gas tank. Routinely checking the fluids will help you notice if you have a sudden decrease.

Worn Gears

The gears in the transmission latch onto each other while your car is in use. These gears are designed to fit snugly without wobbling around.

However, the gears can begin to wear down over time. They’ll start to struggle to engage with each other, causing problems when the engine shifts gears. Old and worn gears can eventually result in transmission failure.

Some signs that your transmission might be headed toward failure include:

  • Unusual noises
  • Slipping gears
  • Burning smell
  • Not going into gear
  • Your car’s check engine light goes on

You need to make an appointment with a mechanic if you notice any of the above issues with your car.

Clogged Transmission Filter

Like your car’s air filter, the transmission filter is intended to keep the transmission fluid clean. A clogged filter can affect how clean the transmission fluid is.

It can also stop fluid from getting into the transmission altogether. If the transmission doesn’t get fluid, it can fail. Inspecting and replacing your transmission filter should get done annually.

Damaged or Worn Torque Converter

Your vehicle’s torque converter is responsible for transferring power from the engine to the transmission. Once powered, the transmission will have the energy needed to smoothly shift into the next gear.

Your torque converter can become damaged over time. You’ll typically hear a brushing or grinding sound if there’s something wrong with it.
