Frequently Asked Questions

How often should I change transmission fluid?

Manual: 30,000–60,000 miles. Automatic: 60,000–100,000 miles normal conditions. Trucks that tow or off-road: follow severe duty — 20,000–25,000 miles.

What’s the difference between a fluid change and a transmission flush?

A pan drain removes 30–50% of fluid. A flush replaces nearly all of it including the torque converter. For heavily contaminated systems, a flush is more thorough.

Can I just top off my transmission fluid?

Topping off doesn’t remove degraded fluid. Old fluid that’s lost its protective properties is still circulating. A proper change is what protects the transmission.

What does burnt transmission fluid smell like?

A sharp, acrid smell — distinct from engine oil. If you notice that combined with rough shifts, get it checked promptly.

Do you service all transmission types?

Yes — automatic, manual, CVT, and 4WD transfer cases. Gas and diesel, all makes. Hillsboro, Beaverton, and Portland metro.
