If you've been putting off that transmission service, it might be time to reconsider. At Wayside Garage, we recently had a 2014 Ford C-Max come in with a fluid leak that seemed to be engine oil at first. Upon inspection, however, we discovered it was actually transmission fluid leaking from a worn transmission cooler line. This isn't uncommon, especially in older vehicles. Over time, seals can become brittle, allowing transmission fluid to leak and cause serious damage.
What Causes Transmission Leaks?
Transmission cooler lines are vital to regulating the temperature of your transmission. These lines transport fluid to the cooler, preventing the transmission from overheating. Unfortunately, the seals that connect the cooler lines to the transmission can become hard and brittle with age and mileage, allowing fluid to seep out. Once the fluid leaks, your transmission could face overheating and internal damage.
In this case, we also noticed the transmission fluid had deteriorated, turning color and smelling burnt. That’s a clear sign it’s time for service. Catching it early and getting the fluid replaced and the cooler line repaired avoided a much more expensive transmission repair.
The Importance of Regular Transmission Service
Transmission fluid plays a critical role in lubricating the moving parts of your transmission and keeping it cool. As vehicles age, regular transmission service is necessary to prevent wear and tear, as well as costly repairs. At Wayside Garage, we recommend servicing your transmission every 30,000 miles or every three years, whichever comes first. This service includes replacing the fluid, inspecting the transmission, and addressing any potential issues before they escalate.
Signs You Need Transmission Service:
- Fluid leaks under your car
- Delayed shifting or slipping gears
- A burnt smell or discolored transmission fluid
- Strange noises while driving, especially when shifting gears
The Cost-Effective Approach to Car Ownership
Maintaining your vehicle with regular inspections and transmission service is much more affordable than replacing the transmission—or worse, the entire car. Transmissions are one of the most expensive components to replace, but with routine service, you can extend its lifespan and avoid major repairs.
