Drivers often wonder whether they need a transmission flush or a fluid change. While both services replace transmission fluid, they have significant differences in effectiveness and safety, especially depending on mileage.
Transmission Fluid Change
- Replaces about 60-75% of old fluid.
- A safer option for vehicles over 70,000 miles.
- Helps maintain fluid integrity without causing internal damage.
- Performed as a drain and fill or pan drop with filter replacement.
Transmission Flush
- Uses a machine to replace 99%+ of old fluid.
- Best for newer transmissions under 70,000 miles.
- Can dislodge debris in high-mileage vehicles, potentially causing damage.
Which One is Right for Your Vehicle?
Flush (Under 70K miles)
✅ Removes nearly all fluid and contaminants.
✅ Keeps new transmissions running smoothly.
✅ Helps prevent early wear.
Drain & Fill / Pan Drop (Over 70K miles)
✅ Less stress on the transmission.
✅ Removes most fluid while maintaining internal stability.
✅ Ensures proper lubrication and cooling.
If your vehicle has under 70K miles, a power flush may be beneficial. If it’s over 70K miles, opt for a fluid change or pan drop instead. Book your transmission service today at AdvancedTransmission.com to ensure long-term performance.
