At Signal Garage, we’ve seen it all when it comes to transmission maintenance. As a community-involved, family-owned auto repair shop in St. Paul, Minnesota, we know how important it is to keep your vehicle running smoothly, especially during the summer months. So today, I want to shed some light on a common question we get: what’s the difference between a transmission fluid change vs a transmission flush?

Understanding Transmission Maintenance

Before diving into the differences, let’s understand why transmission maintenance is crucial. Your transmission is a vital component of your car, responsible for transferring power from the engine to the wheels. So, keeping it in good condition ensures your car operates efficiently and can help prevent costly repairs down the road.

Transmission Fluid Change

A transmission fluid change involves draining the old transmission fluid and replacing it with new fluid. This process typically involves:

1. Draining the Fluid: The old fluid is drained from the transmission pan.
   
2. Replacing the Filter: If applicable, the transmission filter is replaced to ensure no contaminants remain.
   
3. Adding New Fluid: New transmission fluid is added to the system.

Benefits of a Transmission Fluid Change:

1. Cost-Effective: Generally, a fluid change is less expensive than a flush.
   
2. Quick Service: This procedure is relatively quick, making it a convenient option for routine maintenance.

However, it’s important to note that a fluid change may not remove all the old fluid, leaving some contaminants behind.

Transmission Flush

A transmission flush, on the other hand, is a more comprehensive procedure. It involves:

1. Connecting a Flush Machine: A machine is connected to the transmission system.
   
2. Pumping Out Old Fluid: The old fluid is completely pumped out of the transmission system.
   
3. Adding New Fluid: Fresh transmission fluid is pumped into the system.

Benefits of a Transmission Flush:

1. Thorough Cleaning: A flush removes nearly all the old fluid and contaminants, offering a more thorough clean.
   
2. Improved Performance: With all the old fluid removed, the new fluid can operate more efficiently, potentially improving transmission performance.

Which One Should You Choose?

Choosing between a transmission fluid change and a flush depends on several factors:

1. Vehicle Age and Condition: Older vehicles or those with high mileage might benefit more from a flush to ensure all contaminants are removed.
   
2. Manufacturer Recommendations: Always check your vehicle’s manual for manufacturer recommendations. Some may specify a preference for either a fluid change or a flush.
   
3. Driving Conditions: If you frequently drive in harsh conditions or tow heavy loads, a flush might be more beneficial to ensure your transmission remains in top shape.

Our Recommendation at Signal Garage

At Signal Garage, we recommend regular transmission maintenance as part of your vehicle’s routine care. For most drivers, a fluid change performed at the recommended intervals is sufficient.
