Your vehicle transmission filter is a very vital component in your vehicle, since it’s the front line of defense when it has to do with keeping contaminants out of your transmission fluid. Most automobile manufacturers advise a transmission filter replacement every 2 years, or every 20,000 miles (anyone that comes first). When your mechanic changes the filter, he or she should equally change the fluid, and change the transmission pan gasket.
Symptoms that your transmission filter requires replacement
Outside of the regular replacement, you may observe signs that a transmission filter replacement should be done sooner. Here are some indications that replacement is in order:
- You can’t change gears: If you can not change gears easily, or at all, then there could be an issue with the filter. If the gears grind, or there’s a sudden surge in power when you shift, this could equally be an indication of a faulty filter.
- Noise: If you observe rattling, and you can’t explain it any other way, you’ll definitely have to inspect your transmission. It could be that the fasteners require to be tightened, or it could be that the filter is full of debris.
- Contamination: The transmission filter, as we have noted, works to keep contaminants out of the transmission fluid. If it’s not doing its job well, the fluid will get too dirty to work properly. In the worst case scenario, the fluid can burn and result in you requiring expensive transmission repairs. You should inspect your transmission fluid on a regular basis – not just to be sure that it’s at the proper level, but see that it’s clean.
- Leakage: If the transmission filter is not fitted correctly, it could leak. Leakage could equally be due to a problem with the transmission itself. There are many gaskets and seals in your vehicle transmission, and if they get misaligned or dislodged, they’ll leak. Puddles under your vehicle are a sure tip-off.
- Smoke or a burning smell: If the filter is clocked, you could observe a burning smell, or even see smoke coming out of your engine.
