Engine shavings, dust, and grime can all cause havoc once they contaminate your car's transmission fluid. Good thing your car's transmission assembly is equipped with a filter that prevents the fluid from turning into a contaminant-filled sludge. However, as time goes by, the filter will eventually clog up, making it inefficient. This is why experts recommend that you change the transmission filter every 25,000 to 30,000 miles to ensure longer-lasting performance. To help you find the right filter for your ride, consider the following factors:
Felt - Most of today's cars use either felt-,screen-, or, paper-type materials for their transmission filters. The most common type is the felt filter, which is usually made of polyester. Considered a depth filter because it traps contaminants within various layers instead of just on the surface, it can efficiently sift out small and large particles and won't easily get clogged.
Wire mesh - Another commonly used material type used is wire mesh. Take note that this particular kind of filter is typically used by Asian car manufacturers. As a screen filter sifts dirt, metal, and other debris, fluid flow is reduced. The openings of the wire mesh are relatively larger, so only bigger particles are trapped.
Paper - Some cars use paper-based materials for their filters, which are basically made from Dacron fabric or cellulose. Compared to a screen filter that uses a wire mesh, a paper filter is more effective because it can prevent smaller particles from going through. However, this filter type can easily clog, greatly reducing fluid flow.
The right kind of transmission also depends on whether you use your car for daily commutes, hauling heavy cargo, or racing. Keep in mind that when you push your vehicle to its limits, you're also pushing the entire transmission assembly to work harder. For trucks or racing cars, opt for a transmission filter that's specially designed for heavy-duty performance.
Transmission assembly features
If your vehicle uses an automatic transmission that's built with a deep oil sump for more efficient cooling, you need a special type of filter that's designed to reach the transmission pan's bottom. You can check your car manual to confirm the type of transmission assembly you have.
Don't forget to check the brand since not all filters sold today are of the same quality. Go for more established labels since they usually offer reliable warranties for their products. Your ride's automatic transmission assembly relies on the filter for a smooth performance, so be sure to equip it with a high-quality filter.
