One of the most common causes of transmission problems is also one of the easiest to avoid: a clogged transmission filter. To resolve this issue, all you need to do is clean or replace the dirty filter, and you’re good to go. Unfortunately, many people forget to complete this essential maintenance task, which can have a variety of negative effects on the lifespan and operation of their transmissions and potentially require drivers to replace their transmission. To prevent this problem from causing substantial damage, keep an eye out for these common signs of a clogged transmission filter and how to fix it.
The Role of a Transmission Filter
A transmission filter removes any dirt, metal particles, or other debris in your vehicle’s transmission fluid. In doing so, it facilitates the smooth flow of fluid throughout the transmission to prevent moving parts from grinding against each other or other operational issues.
Symptoms of a Clogged Transmission Filter
If a transmission filter becomes clogged, you will notice several warning signs. Being aware of these red flags will allow you to resolve the issue as soon as possible to prevent damage from befalling one of the most crucial components of your vehicle. Below, we will list some of the most notable signs of a clogged transmission filter.
Transmission Fluid Leaks
When a transmission filter becomes clogged, the fluid inside of the system won’t flow as smoothly as it should. As a result, several internal components, such as seals, gaskets, and bearings, may experience premature wear and tear or become loose. In such cases, transmission fluid may begin to leak out of the system. If you notice even a small fluid leak coming from your vehicle, you should immediately look for the source of the issue to prevent serious transmission issues from developing.
Unusual Noises
Strange noises coming from your vehicle are almost always a sign that something is wrong. As such, you should never simply ignore them. In some cases, unusual sounds are the result of a clogged-up transmission filter.
For example, if you hear rattling noises that sound like metal is hitting against metal, inspect your vehicle. If you don’t uncover any obvious sources of the noise, such as a loose exhaust hanger or a faulty catalytic converter, take a closer look inside your vehicle’s transmission. In the case of a blocked filter, it will restrict the flow of fluid, which may cause the rattling noise you hear.
In addition to rattling noises, a blocked transmission filter may also result in strange sounds while your vehicle is in neutral. While in neutral, your vehicle should make almost no noise at all. With a blockage in your transmission filter, however, it won’t be able to flush out contaminants, which will flow through your transmission and create strange sounds throughout the process.
Burnt Smells
In addition to strange noises, you may also notice some strange smells coming from your transmission if your fluid filter has become clogged. Namely, the fluid in your transmission may start to emit an unpleasant, burnt scent.
As previously stated, when a transmission filter gets clogged, fluid will not flow through the transmission smoothly. Without proper lubrication, the system’s moving components may grind against each other and create excess heat. If temperatures in the transmission climb too high, the transmission fluid may begin to burn. Thus, the fluid may start to release a burnt smell.
When transmission fluid is in good condition, it will typically give off a somewhat sweet, almost sugary scent. If the fluid smells like it is burning, replace it and check your filter to see if it is the cause of the issue. Because overheating is the leading cause of transmission problems and failure, you should never disregard this symptom without first investigating.
Problems Shifting
You may also experience shifting issues with a clogged transmission filter since the gears won’t have ample lubrication to function properly. Instead of seamlessly shifting from one gear to another, your transmission may hesitate or slip during the shifting process. If you notice that your transmission is not shifting normally, take a look at your filter to see if it is to blame.
Contaminated Transmission Fluid
Another of the most common signs of a clogged transmission filter is contaminated fluid. When a transmission filter becomes too blocked up, it can’t effectively perform its purpose of removing contaminants from the fluid. As a result, dust, metal particles, and other debris may start to accumulate inside your system.
Ideally, you should check your transmission fluid at least once a month for any signs of contamination. If you notice any particles floating around, or if the fluid appears discolored, have your mechanic flush the system and take a look at your filter to make sure it’s clear of clogs.
How To Fix a Clogged Transmission Filter
Now that you know some of the signs of a clogged transmission filter, let’s talk about how to fix it. As previously mentioned, resolving the issue of a blocked-up transmission filter is pretty simple. All you need to do is locate the transmission filter in your vehicle. Typically, the transmission filter sits above the transmission pan and below the pickup tube.
Once you’ve located the transmission filter, you will need to remove the drain plug. If your transmission does not have a drain plug, you must remove the transmission pan to drain the fluid. Then, you can remove the transmission filter and either clean it or replace it with a new one.
While this task is not necessarily difficult, it can get a bit messy and time-consuming. Depending on your transmission, you may also need special tools to access the transmission pan and remove it. As such, you may want to enlist the help of a professional to replace the filter quickly and cleanly.
