The odyssey in modern English originally means traveler, originated from ancient Greek mythology and is a symbol of romantic adventure. At the beginning, when conducting development and research, the research and design staff of Honda in Japan followed the journey described in the ancient Greek heroic epic and traveled all over half of Europe to seek the source of its romantic ideas. In the end, an Odyssey prototype was designed in a European romantic and comfortable style. When the first time I first met the Odyssey, the viewer’s first instinct was big. Yes, the body length of 4765mm and the slightly lower body height make the Odyssey look like a slender young woman from the side; however, if the camera turns forward, the highly personalized front face design reveals the concise and powerful design style of industrial design: The long and slender finished lights look like squinting and aim at the road surface in front. The front air intake grille, which is concave and integrated with the lights, highlights the three-way air intake style. Falling along the tangent line on the inside of the car light to the end, there is a relatively regular quadrangular air intake. The unobstructed entrance design seems to swallow the road ahead and hangs tightly in the air.
The 2015 Odyssey features a new family-style front face, and the chrome-plated three-banner front air intake grille is more classy than the mid-screen of the 2013 low-profile model.
The tail changes are mainly concentrated on the taillights. The 2015 taillights have become more slender and LED light sources have been added. It has been greatly improved in aesthetics and practicality. At the same time, chrome-plated decorative strips have been added above the tailgate handle, which has significantly improved the sense of class.

The car that came to the store for repair today is a 2015 Honda Odyssey 2.4L Smart Edition, equipped with a CVT CY1A stepless transmission (CVT).

Kilometers traveled: 37053 kilometers.

After the assembly is completed, the test run is ended and the fault is cleared.
This maintenance is mainly due to the failure of the gearbox valve body and the wear of the internal chain cylinder. We mainly replace the gearbox valve body and chain cylinder.
Friendly reminder: Due to the rising temperature in summer, the vehicle will feel frustrated and lock up. In serious cases, the vehicle will not be able to move, the fuel consumption will be too high, and the quality of shifting is poor. If the above situation occurs, please repair it promptly! Please pay attention to maintaining your car!
