Frequently Asked Questions
How often should transmission fluid be changed?
Manual transmission: every 30,000-60,000 miles. Automatic: every 60,000-100,000 miles. CVT: every 60,000-90,000 miles. Check your owner's manual — some manufacturers claim 'lifetime' fluid but many mechanics recommend changes at 60K-80K regardless.
Is a transmission flush safe?
For transmissions maintained regularly, yes. For high-mileage transmissions (150K+) that have never had fluid changed, a flush can dislodge debris and cause issues. In that case, a gentle drain-and-fill is safer. Consult a trusted mechanic.
