It is important to understand that various transmissions use different types of transmission fluids. Our Warren transmission shop offers several different types of transmission fluid brands, all of which are of excellent quality. J.B. Dlco & Multistate Transmissions recommends you change your transmission fluid every 30,000 miles as part of a regular maintenance schedule for your vehicle. When you bring your vehicle to our Warren transmission shop for a transmission fluid change we will also replace your filter, the pan gasket, and peform a final leak-check followed by a thorough road test.
