While it may surprise you, your vehicle functions similarly to how the human body functions. When you get sick and don’t take care of yourself, your health typically gets worse. Sometimes, it can affect other parts of your body too. Likewise, when you are seeing signs of transmission failure, not taking care of the issues will make it worse. It can also affect other parts of the vehicle such as the driveshaft and suspension. 

A vehicle’s transmission is key to its mobility and in order to keep it properly functioning, it’s important that you know how to prevent transmission failure. Take a look at some of the key transmission failure signs and how you can get ahead of them to prevent your vehicle from having a serious mechanical issue later on. 


8 Tips to Help You Prevent Transmission Failure

#1 Check Your Transmission Fluid Regularly

One of the easiest ways you can prevent transmission failure is by regularly checking the transmission fluid level, color, and smell of your vehicle. In order for your transmission to function properly, it requires a certain type of fluid to keep the gears lubricated and prevent them from grinding. If the transmission fluid levels get too low, the gears will begin to grind against one another and cause damage within the transmission and its other components. Also, keep in mind that there are different types of transmission fluids for different types of vehicles. Be sure to check your owner’s manual to determine which type of transmission fluid is recommended for your vehicle as this can also affect the gears and cause damage to the transmission.  

  1. To check your transmission fluid, first, begin by starting the engine. To accurately check the fluid level and color, the liquid must be tested while warm. So, park your vehicle on a flat, level surface and leave it idling.
  2. Next, pull out the dipstick, wipe it clean, replace it slowly, and then pull it back out. Check to see how high the fluid comes up on the dipstick to determine its level (Note: there are lines for “low” and “high” labeled on the dipstick to make this more clear).
  3. Then, take a clean, preferably white or light-colored rag, and wipe the dipstick to check its color. If your fluid is in good condition, it should have a reddish-pink color. And if it’s getting to the point of needing replacement, the color will turn brownish-red or have noticeable dirt and other contaminants.

#2 Always Properly Switch Gears

Changing gears properly is essential to keep your transmission running and functioning as it should. Your transmission is a delicate mechanism and shifting between gears improperly can lead to serious damage. Most of the time this is unintentional, like if you accidentally hit the gear shifter into reverse when you’re driving or skip 2nd and go straight to 3rd. However, it’s also very common for drivers to shift into park while their vehicle is still in motion. Regardless of which gear is changed, it’s important that you do so at the appropriate time. To avoid putting unnecessary wear and tear on your transmission, try being more conscious when changing gears.  

#3 Use Your Parking Brake

Another way to prevent unnecessary wear and tear on your transmission is to always engage your parking brake when putting your vehicle in park, especially when on an incline. Although most vehicles have a pawl, or pin that prevents rolling and keeps the vehicle stationary when in park, you shouldn’t rely solely on this mechanism to keep your vehicle in place. The pawl is easily worn out and is prone to failure when not used in conjunction with the parking brake. 

The parking brake ensures that the vehicle will remain stationary and gives your transmission the brake it needs to function properly. 

#4 Avoid Overheating Your Transmission

Heat is a transmission’s greatest weakness and is one of the leading causes of transmission failure. Excessive heat in or near the transmission can lead to overheating which may result in ruptured seals, cracked or damaged gears, slipping bands, inoperable solenoids, and bearings that fail. All of these concerns can lead to transmission failure and possibly additional mechanical problems. To make sure that your transmission doesn’t overheat, it’s important to periodically check for leaks and top your fluid levels off at regular intervals as specified by the vehicle manufacturer.

#5 Don’t Overload Your Vehicle

Overloading your vehicle by towing beyond your vehicle’s capacity can lead to unnecessary strain on the powertrain transmission which often causes it to overheat. As stated above, it’s vital that you do everything possible to prevent this from happening. One way to do that is to avoid putting excess weight in or on your vehicle. You’ll avoid transmission failure or a mechanical malfunction by simply following the towing capacity set by your manufacturer. 

#6 Let Your Vehicle Warm Up

You’ve probably heard that you should let your vehicle warm-up in the morning on days where temperatures are quite low, but do you know why? Warming up your vehicle for just 30-60 seconds will help the transmission fluid and oil flow through all of the gears to prepare them for driving. It’s key to allow your transmission to get all of its fluids moving before taking off so that all of the moving pieces are properly lubricated and don’t grind together. So, be sure to warm-up your vehicle on those chilly mornings to prevent possible transmission failure. 

#7 Have Annual Powertrain Transmission Check-Ups

During a transmission service, the transmission fluid is drained and then replaced using new fluids. This helps remove dirt and contaminants such as metal shavings that build up within the transmission. If the transmission fluid is full of contaminants, the parts inside the transmission will stop functioning properly and could lead to even bigger problems later on. It’s important to have your transmission regularly serviced so you can avoid a powertrain repair cost.

#8 Never Ignore Transmission Failure Signs

It’s not common for your transmission to fail without first showing signs of a problem on the rise. Typically, transmission failure signs first occur with minor issues that eventually turn into larger issues. So it’s important to notice when your vehicle is trying to tell you that something is wrong. Many of the clues your vehicle will give you can be easily detected using your senses including smell and hearing. Commonly, when there is an existing transmission concern, you’ll hear screeching, grinding, or clanking noises, see transmission fluid leaking from your vehicle, or will smell something burning.
