The transmission is a very complex system and requires regular servicing to keep it working efficiently. As your Ford dealership, we want you to know some signs you need to visit us for a transmission service.

Check Engine Light

As every driver knows, a lit check engine light is a sign of trouble. What isn’t as well-known is that a transmission problem will also cause this light to come on. The engine and transmission work closely together, the engine to generate energy and the transmission to effectively deliver this energy to the wheels so they can move at the required speed.

If the transmission isn’t working correctly, its sensors will detect the problem and inform your computer. The computer then instructs the engine sensors to push the engine to work harder to try to correct the issue. If this doesn’t work, the extra demands on the engine force the computer to trigger the check engine light. We’ll investigate, identify the issue, and repair it.

Transmission Leak

Transmission fluid is stored in the transmission pan at the bottom of the transmission and is pumped from there throughout the transmission. The fluid provides the hydraulic power that allows the gears to shift. The fluid also lowers the temperature in the transmission by cooling hot components as it passes over them and coating them in a protective, friction-resistant film that reduces damage.

The transmission casing is protected against damage from stones or other objects thrown up from the road, but its seals can wear out if it’s not regularly serviced. A fluid leak reduces pressure in the transmission, and you may hear grinding metallic noises as gears grind against each other. Our technicians will replace any worn or damaged seals and refill the fluid to fix this issue.

Humming, Buzzing, or Whining

Ford transmissions are quiet as they shift gears, so you shouldn’t hear anything as they work. Strange buzzing or humming noises just on the edge of hearing are signs your transmission is in trouble. They can be caused by a variety of issues, like low transmission fluid, a damaged transmission bearing, or worn planetary gears.

The sounds can also be caused by worn seals. If this is the case, you’ll usually see red transmission fluid under your vehicle. Whining noises can also develop, and they’re often caused by a worn or damaged torque converter, which connects the engine to the transmission. If the issue isn’t fixed, the noises will grow louder over time and could cause permanent damage. We’ll find the cause of the problem and repair it.
