Transmission Service

Whether you drive an automatic or a stick shift car, truck or SUV, you’ve probably been reminded at some point that transmission service is a recommended maintenance item that needs to be done periodically. You may have wondered just what this service involves. Below you’ll find a few key questions to which we’ve provided answers in the paragraphs that follow:

  • What is the purpose of the transmission in my car?
  • Do all types of transmissions need service?
  • Why is it important to have service for my transmission?
  • What takes place during service of my transmission?

By way of reminder, the transmission in your vehicle is a complex and expensive component that takes mechanical power from the engine and converts it into motion so your car will move. It’s the job of the transmission to send the correct amount of power to the wheels so they move at the correct speed so your car can get you where you need to go.

Your car probably has one of two main transmission types, automatic or manual. Both require periodic transmission service to continue to function as they were designed. Though the specific way in which an automatic transmission works may differ in some ways from how a manual transmission works, service for either type focuses on taking care of the transmission fluid, sometimes referred to as oil.

The fluid in a transmission is similar to engine oil in how it functions. Its purpose is to provide lubrication so friction between moving parts is reduced. It is the friction between metal parts moving at high speeds that causes the parts to wear. As friction happens, minute fragments of metal are released and the parts become worn. These particles, picked up by the oil that circulates, act like an abrasive that creates more wear.

This friction also produces heat that over time will degrade the oil and reduce its ability to lubricate. Transmission service functions mainly to remove oil that is degraded and contaminated and replace it with clean oil able to provide effective lubrication once again. In this way, you get the most years of service from the transmission’s internal parts.

There are 2 main ways a transmission service removes dirty oil so it can be replaced with clean. The first is referred to as a “flush”. In this method, a machine is connected to both transmission cooler lines. As clean fluid is forced in through one line, the dirty fluid is forced out through the other where it is collected by a receptacle in the flushing machine for proper disposal.

The second method is simply to allow the old fluid to “drain” out before new fluid is installed. This may or may not include removing the pan so the filter can also be changed. Some manual transmission vehicles have no drain and the dirty fluid must be pulled out by vacuum before clean fluid can then be installed.

Since recommended intervals for this service vary from manufacturer to manufacturer and shop to shop, be sure to check your owner’s manual and ask your trusted auto repair shop like Dales Auto Care when your vehicle should be scheduled for transmission service.
