How long does the transmission filter last?

Your transmission filter is a very important component of your vehicle because it is the front line of defense when it comes to keeping contaminants out of your transmission fluid. Most car manufacturers recommend changing the transmission filter every 2 years or every 30,000 miles (whichever comes first). When your mechanic changes the filter, they should also change the fluid and replace the transmission pan gasket.

Signs that the transmission filter needs to be replaced

In addition to regular replacement, you may notice signs that the transmission filter needs to be replaced sooner. Here are some signs that a replacement is in order:

• You can't change gears: If you can't change gears easily, or you can't shift gears at all, the problem might be with the filter. If the gears grind or there is a sudden surge of power when shifting gears, this could also indicate a bad filter.

• Noise: If you hear a rattle, and you can’t explain it in any other way, then you definitely need to check the transmission. Perhaps the fasteners need to be tightened, or maybe the filter is clogged with debris.

• pollution: The transmission filter, as we said, prevents contaminants from entering the transmission fluid. If it doesn't do its job efficiently, the fluid will become too dirty to work properly. In the worst case, the fluid can burn out, resulting in a costly transmission repair. You should check your transmission fluid regularly - not only to make sure it's at the proper level, but also to make sure it's clean.

• seepage: If the transmission filter is installed incorrectly, it may leak. The leak could also be related to a problem with the transmission itself. There are a lot of gaskets and seals in your car's transmission and if they get loose or misaligned, they will leak. Puddles under the car are a sure sign.

• Smoke or burning smell: If the filter is clogged, you may smell burning or even see smoke coming from your engine.
