Motor vehicle transmissions have experienced major changes in the last decade. Although automakers use 5- and 6-speed manual transmissions less frequently than in the past, the number of gears in automatic transmissions has jumped from 4 to as many as 10! Certain gearboxes are controlled with paddle shifters mounted on the steering column to recreate some of the power and control of driving a stick. Every year, there are more and more vehicles with a continuously variable transmission (CVT) on the road.
All automotive manufacturers make recommendations about which kind of transmission fluid to use and how often to change it. Your certified NAPA AUTOPRO technician can check your transmission fluid and replace it with the correct product (regular or synthetic, viscosity, etc.), if required.
It’s a good idea to regularly check the level of transmission fluid in your vehicle or ask your certified NAPA AUTOPRO technician to do so during routine maintenance. Low or insufficient fluid can cause internal components to overheat and potentially lead to significant damage.
