The transmission is the most expensive and complex component in your vehicle and benefits from fluid and filter changes just like your engine. The transmission is what transfers the power of the engine to the driving wheels of your vehicle.
Most vehicle manufacturers now regard this component as "sealed for life".
We recommend that you have your transmission serviced once a year if your transmission uses a non synthetic fluid, and once every two years for synthetic fluid.
The transmission life is shortened and drivability, together with
fuel economy is affected.
