Fluid Type Explained

The 2017 Honda Odyssey was available with two different automatic transmissions: a 6-speed and a 9-speed. It is critical to identify which transmission your vehicle is equipped with before purchasing fluid. The 6-speed transmission uses Honda Genuine ATF DW-1, a synthetic-blend fluid readily available at Honda dealerships and many auto parts stores. The 9-speed transmission, manufactured by ZF, requires a specialized fluid that meets ZF's specifications. While Mopar ZF 8&9 Speed ATF is the officially licensed fluid, other brands such as Valvoline, Castrol, and Liqui Moly offer compatible alternatives.

Service Procedure

A "drain and fill" is the most common and straightforward service procedure. This involves draining the old transmission fluid from the drain plug, and refilling the same amount of new fluid through the fill port. This method typically replaces about a third of the total fluid in the transmission. While a full "fluid exchange" or "flush" will replace nearly all of the fluid, it is often not recommended by vehicle manufacturers. A flush can sometimes dislodge sediment and cause shifting problems, especially in higher-mileage transmissions.

Service Interval

Honda recommends a transmission fluid change every 30,000 to 60,000 miles. For vehicles that experience "severe duty" — such as frequent towing, driving in mountainous terrain, or extensive stop-and-go city driving — the 30,000-mile interval is highly recommended. For "normal duty" driving, consisting of mostly highway miles, a 60,000-mile interval is sufficient. Adhering to these service intervals will help to ensure the longevity and smooth operation of your transmission.

Common Transmission Problems

While the 2017 Honda Odyssey is generally a reliable vehicle, some owners have reported issues with the 9-speed transmission. These include rough shifting, hesitation, and in some cases, premature failure. Some of these issues have been addressed with software updates from Honda, so it is important to ensure your vehicle's powertrain control module (PCM) is running the latest software version. The 6-speed transmission is generally considered to be more robust, with fewer reported issues.
