How it works - 3 simple steps

Step 1
Drop off & inspect

We check transmission fluid color, smell, and condition; inspect the pan for metal particles; road-test to evaluate shift quality; and check for external leaks at the pan gasket, cooler lines, and axle seals.

Step 2
You approve the estimate

We quote the correct fluid type and quantity for your specific transmission — not a generic ATF. CVT, DSG, and sealed automatic transmissions each require different fluid; we match to manufacturer specification.

Step 3
Pick up your car

Post-service road test to verify shift quality. Transmission fluid services completed same day. Major repairs quoted after diagnosis with a written estimate.

Why Mukilteo drivers choose Tom's B&M Auto

Using the wrong transmission fluid is one of the most common causes of premature transmission failure. Toyota WS and T-IV ATF are not interchangeable. Nissan NS-3 CVT fluid cannot be replaced with a universal CVT fluid. We stock manufacturer-specified fluids for all major makes and never substitute.

We see CVT failures regularly on Nissan and Subaru vehicles where the fluid was never changed or changed with the wrong product. CVTs are expensive to replace — a $120 fluid service at 30,000-mile intervals prevents a $4,000+ replacement. We'll tell you where your vehicle stands.

Manufacturer-specified ATF, CVT, or DSG fluid — not universal substitutes.

Transmission Service near Mukilteo - frequently asked questions

From Tom's B&M Auto - serving Mukilteo and the greater Seattle metro.

How does Mukilteo traffic affect my transmission service interval?
Mukilteo's ferry approach braking, Speedway grade descents, and Boeing shift traffic creates above-average vehicle wear. The Mukilteo Speedway grade is one of the steepest in Snohomish County — we see the resulting wear regularly. We recommend an inspection every 12,000 miles or annually — whichever comes first.
