 Transmission, gearbox, and coolant service intervals range from 30 to 60 to even 90,000 miles. At Walla Walla Transmission, we know that transmission fluid, like engine oil, breaks down at varying rates depending on driving conditions and habits, which can make your vehicle vulnerable to costly transmission repairs. And while transmission repair is our specialty, we want to help you avoid costly repairs with our expert transmission maintenance service. Come see us at Walla Walla Transmission just north of West Rose Street at 204 Bennett, Walla Walla.
