Obviously, most car owners don’t exactly replace their rides after 5 years. That’s approximately 5 years or 100,000 km, though the timeline and mileage can vary depending on the make and model.įor argument’s sake, the carmaker will argue that the “lifetime” claim is completely accurate as once said car surpasses 5 years or 100,000 km, it’s considered obsolete by their definition. In fact, some carmakers that implement a lifetime transmission fluid in their vehicles design the transmission case in such a way as to prevent easy access to replace the fluid.Ĭircling back to the definition of “lifetime,” it’s generally understood to be the span of the car’s warranty. Of course, the owner can opt to have an independent workshop carry out the task but that would likely result in the warranty being voided. As such, the official service center won’t perform an ATF replacement, even if requested by the owner. That’s due to the fact that modern cars are all designed with planned obsolescence in mind, meaning that the carmakers consider them obsolete after a certain mileage has been clocked.Ĭorresponding with that, they designed the transmissions usually traditional torque converter automatics, with a sealed case that doesn’t cater to replacing the fluids within.įor example, the scheduled maintenance list for a 2015 Mazda 2 doesn’t carry a suggested interval for the ATF’s replacement. Therefore, “lifetime” transmission fluids wouldn’t need to be replaced at all, right?Īgain, back to the definition of “lifetime.” It implies there’s an end to the car’s life, or a point when it becomes obsolete.

Most transmission fluids such as ATF (automatic transmission fluid), CVT fluid, DCT fluid or manual transmission fluid require replacement after the car has clocked a certain amount of mileage.

Forever implies until the end of time whereas lifetime infers that the existence of something is finite and will cease at some point. To the layman, a lifetime might be mistaken as forever. Nonetheless, much in the same way that Thanos believed wiping out half of all life rather than doubling the amount of resources would prevent the extinction of resources, the term “lifetime” is wide open for interpretation and debate. At face value, this implies that the fluid or lubricant in the gearbox doesn’t have to be replaced for the entire lifespan of the car. Many modern transmissions in cars are now labeled as having a “lifetime” transmission fluid.
