Your transmission is the part of your car or truck that transports power from your engine to the wheels. How your vehicle’s transmission operates will depend on the type- automatic or manual.

Manual and Automatic Transmissions

With manual transmissions, there is a set of gears that are lined up on a shaft. When the driver moves the clutch and gearshift, the gears will move into place. Once the clutch is set free, power is moved from the engine to the wheels. Depending on the gear you choose will reflect the amount of power, or torque, used.

The gears of an automatic transmission are also lined up on the shaft, but the gears will change from the gas pedal. When the driver presses down on the gas pedal, the gears will automatically move, depending on the current speed of the vehicle. When the gas pedal is let go, the gears will cycle down. Your transmission fluid greases up the gears to make the process of switching easier.

How Often Should I Be Replacing Transmission Fluid?

The amount of times you replace your transmission fluid will depend on whether or not your vehicle is automatic or manual. If your transmission is automatic, heat is produced more so there is an increase in carbon created. An increase in carbon will harm the transmission fluid. Gradually, this results in the fluid thickening, causing it to not do its job efficiently. Because manufacturer specifications can vary, you should have your level checked regularly.

Much like an automatic transmission, the recommendations for replacing can vary, but for different reasons. While most suggest replacing at 30,000 to 60,000 miles, vehicles with “high stress” transmissions should really change the fluid every 15,000 miles. An example of a high stress manual transmission would be if you were taking lots of short drives, where the gears are shifting more.

Indications You Need to Check Your Transmission

For drivers that haven’t reached the mileage suggested from the manufacturer, have your transmission looked at if you notice the following:

  • If your car is running, but not moving and you can hear a grinding sound underneath.
  • Issues with shifting gears
  • If your car doesn’t move when you engage the gas pedal or it moves out of gear
