Transmission Fluid Filter
Catches wear debris before it reaches the valve body and solenoids, where a particle in a spool valve bore does real damage. Usually inside the pan, so changing it means dropping the pan — which is also the moment to look at what has collected there. Fine grey paste is normal wear; glittering metal flakes or friction material means the transmission is coming apart internally, and that observation costs nothing while the pan is already off. A restricted filter starves the pump and causes pressure faults that read as solenoid or clutch problems.
Also known as: transmission filter, atf filter, gearbox filter, trans filter, sump filter

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
