From transmission concept to production: how we support OEMs at every stage
Choosing the right transmission is a critical part of developing any off-highway machine. It affects performance, efficiency, operator experience and long-term reliability.
At Turner, we work side-by-side with OEMs throughout the entire process, from early concept through to production and beyond. Our team of engineers and specialists provide support at every stage, helping customers make informed decisions and develop solutions that meet their exact requirements.
1. Starting with the right information
Every project begins with understanding the machine.
After initial contact, we work closely with OEMs to gather detailed information about the application, as well as key specifications. This information forms the foundation for all performance calculations and ensures we’re working towards the right outcome from the start.
What information is needed to recommend gear ratios and confirm performance targets?
To recommend the right gear ratios and confirm performance targets, we need to build a clear picture of the machine and how it will be used.
This typically includes:
- Machine weight and configuration
- Required operating speeds and gradeability
- Torque and tractive effort requirements
- Engine characteristics and power curve
- Axle ratios, tyre sizes and driveline layout
- Typical duty cycles and operating conditions
By grounding decisions in real application data, we can help OEMs avoid compromises later in development and ensure targets are achievable before physical testing begins.
2. Starting with the right information
Once we understand the product and application and review this in detail with the OEM, we carry out performance calculations to identify the most suitable transmission and gear ratios.
Our goal is always to meet or exceed the required performance targets, while ensuring the solution works as part of the wider machine system. This includes considering engine characteristics, duty cycles and the overall machine design.
We don’t take a one-size-fits-all approach. Instead, we tailor our existing transmission platforms to suit each application, making adjustments wherever needed to deliver the perfect fit. You can explore examples of our manual and powershift transmission range to see how we support different applications.
How do you tailor an existing platform to our machine’s requirements?
By tailoring proven Turner transmission platforms to suit each application, it means that OEMs can benefit from established designs, while still achieving a solution that is aligned with their machine’s performance targets, installation requirements and operating conditions.
Depending on the application, this may include reviewing gear ratios, integration requirements, mounting considerations and other application-specific factors to ensure the transmission works effectively as part of the wider machine system.
3. Supporting integration across the machine
A transmission is just one part of a larger system; it must integrate seamlessly with the engine, axles and the rest of the machine.
We support OEMs through this integration process, ensuring compatibility in terms of power, fit and function. This includes working with engine power curves, available space within the machine and mounting requirements.
Integration also impacts operator experience. Gear shifting, machine response and overall feel are all things that can influence how the machine performs in real-world conditions. By working closely with OEMs, we help ensure the final result meets both technical and operator expectations.
4. Adapting as requirements evolve
We find that machine development is rarely a linear process. Requirements can change as OEMs respond to their own customers, market demands or regulatory needs.
That’s why we build flexibility into our approach. As specifications evolve, we revisit performance calculations, refine recommendations and adjust the solution where needed.
Even small changes can have wider impacts on performance and timelines, so clear communication and collaboration are essential. Our focus is always on delivering the right transmission solution for the application, rather than a quick or generic fix.
5. Supporting testing and validation
Before production begins, it’s essential to validate performance and reliability.
We support OEMs through both theoretical analysis and physical testing. Initial validation takes place at our dedicated test facility in the UK using test rigs to assess factors such as shift points, torque and speed. This is followed by on vehicle dynamic testing, where sample transmissions are installed in machines and evaluated in collaboration with the OEM.
If performance targets aren’t fully met, we work together to refine the solution. This may involve adjustments to hardware or control systems to meet customer and legislative requirements.
Once the design is validated, we support pilot builds and pre-production phases, ensuring that manufacturing processes and quality standards are in place.
6. Supporting production and long-term performance
Support doesn’t stop once a machine goes into production.
We provide ongoing technical support through dedicated teams who work directly with OEMs to support any field related enquiries or issues.
We also provide updated service manuals when required and support aftermarket requirements through specialist parts expertise, helping OEMs maintain both current and legacy transmissions. If you need support at any stage, you can get in touch with our team.
7. Maintaining consistent quality
All Turner transmissions are manufactured at our facility in Hosur, India. Production was transferred from Wolverhampton over a decade ago and we are proud of our quality journey.
The move to India has contributed to ever-increasing quality levels and has helped us to scale production while maintaining consistent standards, supported by a strong focus on process, precision and testing.
How do OEMs select a transmission supplier?
Choosing a transmission supplier is about more than selecting a product. From our experience at Turner, OEMs typically look closely at the quality of the partnership behind the transmission.
Key factors include proven application experience in similar machines, the ability to collaborate early in the development process, confidence in long-term support and trust in the supplier’s engineering expertise.
We’re proud that our team is small enough to offer a personalised, responsive approach, while being backed by the strength and credibility of Caterpillar. This combination allows us to build strong, long-term relationships based on trust and technical expertise.
Across the global backhoe loader market, approximately one in five machines is powered by a Turner transmission. This reflects both the trust placed in our products and the strength of our engineering approach.
Looking for a transmission partner?
Developing a transmission isn’t just about selecting a component. It’s about building the right solution for each machine, supported by the right expertise.
At Turner, we are part of the process from the earliest stages of evaluation through to final engineering sign-off and production. By working closely with OEMs throughout, we help reduce risk, improve performance and deliver solutions that are built to last.
