Normal use, meaning regular everyday driving, can wear out the transmission or parts within the transmission, producing metal shavings in the fluid. Metal shavings are little warning signs that need to be addressed and related to the care and maintenance of the transmission. This can even occur when you haven’t added any performance parts.

A few reasons for metal shavings can be choosing a bad grade of fluid or a cheap brand, an overdue oil change well over the manufacturer’s suggested mileage, or over-revving the engine, where the fluid does not have enough time to coat and lubricate the moving parts. In the general maintenance automotive industry, these are prime examples of some causes for the metal shavings. It is normal to find dust or smudge for normal wear & tear, though.

If you find metal shavings in your oil, either take it to a qualified transmission technician (or if you’re competent enough to know what to look for) and check all the transmission components. Transmissions can handle a lot of pressure and HP if set up correctly, though the components are not eternal or bulletproof. Be sure to check if your vehicle has any transmission or differential recalls. Remember to maintain your vehicle per the manufacturer’s recommended guidelines.
