The transmission handles a hugely important part in how your car functions. It’s linked to the rear portion of your engine and sends power from the engine to the wheels. Without a transmission, a car simply cannot move. The transmission filter is an important part of that system and is found above the transmission pan, which catches any excess fluid, and below a pickup tube that links to the oil pump, which regulates the pressure of fluid in the transmission. The transmission filter functions as a sieve to collect contaminants like dirt and debris before transfering lubricating fluid to the transmission itself.
How often to replace a transmission filter
Over time, bits of metal that may have flaked off from metal-to-metal contact and other grit and grime can dirty a transmission filter. Although every car has its own optimal maintenance requirements that can usually be found in the owner’s manual, the general consensus among mechanics is that the transmission filter and fluid should be changed every 25,000 miles. Replacing the fluid and filter is a quite messy and time-consuming job since few transmissions are equipped with a drain plug. That implies the only way to reach the transmission filter and let old fluid to escape is by removing the transmission pan. This is usually in an awkward-to-reach area and needs special tools, which is why you may opt to consult a certified mechanic about the proper times to replace the transmission filter and fluid for your car and enlist him or her to do the job for you if need be.
Often, when it’s time to change the fluid and filter for a transmission, owners buy an entire fluid filter kit instead of just the filter itself. The actual transmission filter components are few, but the kits include a little extra related hardware that it’s wise to go ahead and change them as a preventative measure while the transmission pan is already off and that region of the transmission system is easy to access. These are the usual items that are generally included in a transmission filter kit:
- Transmission Filter:The filter resembles a metal plate with slats, which is where the transmission fluid passes through. Inside those slats is a fibrous medium, which catches any contaminants before the fluid gets into the transmission.
- Gasket:The gasket makes sure that a tight fit between the transmission filter assembly and transmission pan, so no fluid escapes while it is in circulation. It is kept firm in place by an array of bolts around the perimeter of the pan or may be made to simply pull off with a little effort. These gaskets can either be made of cork or ridged rubber.
- Pickup Tube:The pickup tube, which links the transmission filter assembly to the oil pump is also included as components of the kit.
- Seal:The last component of a transmission filter kit is an O-ring style rubber seal that provides a tight fit between the pickup tube and the transmission case.
How a transmission filter operates is a relatively straightforward process with few parts involved. If, however, there is any issue regarding how the transmission filter functions or you feel it is time to change your filter or fluid.
