Honda's Ohio Transmission Plant Is Now A Hybrid Powerhouse

Small But Vital

Automotive production is spread out into multiple parts and facilities; not all parts that make up a car are built in the same area or by the same people. To keep things flowing and maximize cost efficiency, most brands build multiple facilities that produce parts for their production models.

One of Honda's most important parts facilities is celebrating a big milestone and is responsible for producing a vital part for all cars.

Honda Associates 30th Anniversary

Honda's Transmission Plant-Ohio (TMP-O), based in Russells Point, Ohio, is celebrating its 30th anniversary, honoring a legacy of flexible manufacturing. The plant began production in 1996, first building a 4-speed automatic transmission, then progressing to building a 5-speed automatic transmission in 2005, and a 6-speed automatic transmission by 2010.

As modern mobility requirements changed, so did the plant; it is now responsible for producing the CVT and the award-winning two-motor hybrid system, which is available in the Honda CR-V, Accord, and Civic and is standard in the Prelude.

In fact, TMP-O even has global specification builds, making it a leader in Honda's overall global manufacturing footprint. Kylie Huber, TMP-O Manufacturing Division lead, says, "For 30 years, TMP-O has stood at the center of Honda's progress – driving innovation and demonstrating the power of passion and craftsmanship."

The plant itself is 1.1 million square feet and employs 1,200 skilled workers. It has an annual capacity to produce 1 million transmissions and gear shifts, along with 500,000 two-motor hybrid systems, transfer cases, and differentials for four-wheel-drive vehicles.

Honda and Ohio

Honda's presence in Ohio is long-established, serving as the epicenter of the automaker's U.S. production. Production began as far back as 1982 in the Marysville Auto Plant, and it is the largest manufacturing employer in the whole state. Going back even further, in 1979 Honda began producing motorbikes in Marysville, before venturing to the automotive side, culminating in a 40-plus-year run in the state.
