Who Makes Nissan Transmissions?

Updated on:

Ever wondered what goes on inside your Nissan's gearbox? Or maybe you're facing transmission trouble and need to know where to turn for parts or repairs. The answer to "who makes Nissan transmissions?" isn't always as straightforward as you might think. While Nissan manufactures some of its transmissions in-house, they also rely on partnerships with other major automotive component suppliers. Let's dive into the fascinating world of Nissan transmissions and uncover who's really behind them.

Nissan's In-House Transmission Production: A Proud History

Nissan, like many large automakers, maintains a degree of self-sufficiency when it comes to critical components like transmissions. This allows them to control quality, innovate, and meet specific vehicle requirements.

  • Where are Nissan Transmissions Made? Nissan operates transmission manufacturing plants in several locations worldwide. Japan remains a central hub for their transmission production, housing facilities that produce advanced automatic and continuously variable transmissions (CVTs). Nissan also has transmission plants in other regions, including the United States (Tennessee) and Mexico. These facilities often focus on transmissions for models sold in North America.
  • Why In-House Production Matters: Manufacturing transmissions themselves gives Nissan a significant advantage. They can tailor transmission designs to perfectly match their engines and vehicle platforms, optimizing performance and fuel efficiency. It also allows them to implement their own quality control standards, ensuring that their transmissions meet their rigorous specifications.
  • Examples of In-House Transmissions: Nissan has a long history of developing its own automatic transmissions. The RE4F04A, a popular 4-speed automatic found in older Nissan models, was a Nissan design and manufacture. More recently, Nissan has heavily invested in CVT technology, and many of their CVTs are produced in-house.

The Jatco Connection: A Key Partnership

While Nissan does produce many transmissions internally, a crucial partner in their transmission supply chain is Jatco. This relationship is so important it deserves its own section.

  • Who is Jatco? Jatco (Japan Automatic Transmission Company) is a leading global manufacturer of automatic transmissions and CVTs. What's unique about Jatco is that Nissan is a major shareholder. This close relationship allows for significant collaboration in transmission development and production.
  • Jatco's Role in Nissan's Transmission Lineup: Jatco supplies a significant portion of Nissan's transmissions, particularly CVTs. Many Nissan vehicles, from compact cars like the Versa to larger SUVs like the Pathfinder, utilize Jatco-supplied transmissions.
  • The CVT Revolution: Jatco has been at the forefront of CVT technology, and their CVTs have become ubiquitous in Nissan vehicles. The benefits of CVTs include smooth acceleration, improved fuel economy, and a more responsive driving experience. However, CVTs also have their own set of challenges, including potential durability issues and a different driving feel compared to traditional automatics. We'll discuss more about CVT reliability later.
  • Shared Technology and Development: The close partnership between Nissan and Jatco means that they often share technology and collaborate on transmission development. This allows Nissan to leverage Jatco's expertise in transmission design and manufacturing, while Jatco benefits from Nissan's vehicle engineering and testing capabilities.
  • Example of Jatco Transmissions in Nissan Vehicles: Some of the most common Jatco transmissions found in Nissan vehicles include the JF011E/RE0F10A CVT (used in many Nissan and Mitsubishi vehicles) and the JF015E CVT (designed for smaller vehicles). These transmissions are known for their compact size and fuel efficiency.

Other Transmission Suppliers: Filling the Gaps

While Nissan and Jatco are the primary players in Nissan's transmission ecosystem, they sometimes source transmissions from other suppliers, though less frequently.

  • When Does Nissan Use Other Suppliers? In some cases, Nissan may use transmissions from other suppliers to meet specific vehicle requirements or to supplement their existing production capacity. This is more common for specialized applications or in certain regions where local sourcing is advantageous.
  • Examples of Other Suppliers: While information on specific suppliers is less readily available, it's possible that Nissan sources transmissions from companies like Aisin Seiki (Toyota Group) for certain models or in specific markets. These arrangements are typically driven by cost considerations, regional manufacturing agreements, or the need for specific transmission features.
  • Specialized Transmissions: For certain specialized vehicles, such as heavy-duty trucks or performance cars, Nissan might opt for transmissions from specialized manufacturers known for their expertise in those areas. This ensures that the vehicle has the necessary strength and performance capabilities.

Understanding Nissan Transmission Codes: Decoding the Mystery

Nissan uses a specific coding system to identify its transmissions. Understanding these codes can provide valuable information about the transmission's type, design, and application.

  • How to Read a Nissan Transmission Code: Nissan transmission codes typically consist of a combination of letters and numbers. The letters usually indicate the transmission type (e.g., "RE" for rear-wheel-drive automatic, "CVT" for continuously variable transmission). The numbers often represent the number of gears or a specific design series.
  • Examples of Common Nissan Transmission Codes:
    • RE4F04A: Rear-wheel-drive, electronically controlled, 4-speed automatic transmission.
    • JF011E/RE0F10A: Jatco-manufactured CVT.
    • JF015E: Jatco-manufactured CVT designed for smaller vehicles.
  • Where to Find the Transmission Code: The transmission code is typically found on a sticker or plate attached to the transmission housing. It may also be listed in the vehicle's owner's manual or on a vehicle identification number (VIN) decoder.

Nissan Transmission Reliability: Addressing Common Concerns

Nissan transmissions, particularly CVTs, have faced some criticism regarding reliability. It's important to understand the factors that contribute to these concerns and how to mitigate potential issues.

  • CVT Reliability Concerns: Some Nissan CVTs, particularly early models, have been known to experience issues such as slipping, shuddering, and premature failure. These issues can be attributed to factors such as design limitations, inadequate cooling, and improper maintenance.
  • Factors Affecting Transmission Reliability: Several factors can affect the reliability of any transmission, including driving habits, maintenance practices, and environmental conditions. Aggressive driving, infrequent fluid changes, and extreme temperatures can all contribute to premature wear and tear.
  • Proper Maintenance is Key: Regular transmission fluid changes are crucial for maintaining the health of your Nissan transmission. Using the correct type of fluid and following the recommended service intervals can significantly extend the life of the transmission. For CVTs, in particular, using the specified CVT fluid is essential.
