The technicians at Bud's Transmission Service & Auto Repair understand your time is valuable so we do everything we can to get you back on the road as soon as possible. When you bring your car to our Marysville ~ Everett transmission shop for a transmission check we use the latest technology to perform an external diagnostic service. A diagnostic service includes checking the condition and level of your vehicle's transmission fluid, taking your vehicle for a road test, and external transmission control diagnosis. This service usually is completed in about 90 minutes. Ready to schedule an appointment?
