Description
Keyser Manufacturing Automatic Transmissions 062 SG1500 – Professional Overview
The Keyser Manufacturing Automatic Transmissions 062 SG1500 is a specialized Bert transmission developed around a lightweight aluminum ball spline design. Keyser Manufacturing identifies the unit as the Aluminum Ball Spline Transmission 2nd Gen, with SKU 062 SG1500.
Unlike conventional replacement automatic transmissions designed primarily for passenger vehicles, the 062 SG1500 is positioned for Late Model and Modified racing. Its design focuses on reducing unnecessary rotating mass and limiting driveline bind, two factors that can influence how effectively a racing vehicle transfers power to the rear wheels.
The second-generation design is particularly focused on weight reduction. Keyser states that the transmission provides 50% less rotating weight and describes it as a low-drag unit. The manufacturer lists a total weight of 45.7 pounds.
This makes the 062 SG1500 fundamentally different from the remanufactured OEM-style transmissions commonly used for street vehicles. It is a purpose-oriented racing transmission intended for builders and racers who are concerned with drivetrain response, weight, and traction.
Racing Applications and Intended Use
The 062 SG1500 is designed for Late Model and Modified racing applications. Keyser specifically positions the second-generation Bert aluminum ball spline transmission for racers competing in these types of vehicles.
Its ball spline configuration is intended to address driveline behavior rather than simply provide a conventional gear-changing function. By reducing driveline bind, the transmission is designed to allow the rear suspension to move more freely and smoothly.
This characteristic becomes particularly relevant on dry slick race tracks, where maintaining mechanical grip can be critical. Keyser explains that the reduced driveline bind allows the rear suspension to move faster and smoother, improving traction under these conditions.
Because of this specialized design, the 062 SG1500 should be considered when building or maintaining a compatible racing drivetrain. It is not presented by the manufacturer as a general-purpose automatic transmission for ordinary passenger vehicles.
Lightweight Construction and Drivetrain Efficiency
One of the defining characteristics of the Keyser Manufacturing Automatic Transmissions 062 SG1500 is its lightweight aluminum construction.
Keyser lists the transmission at 45.7 pounds, making weight reduction a central part of its design philosophy. The manufacturer also states that the second-generation unit achieves 50% less rotating weight compared with its relevant predecessor configuration.
Reducing rotating mass can be especially valuable in racing applications because drivetrain components have to accelerate along with the vehicle. A purpose-built racing transmission can therefore place greater emphasis on minimizing unnecessary mass than a conventional street transmission.
The aluminum construction also complements the overall focus on weight-conscious racing design. Instead of prioritizing features such as integrated coolers, electronic controllers, or OEM replacement compatibility, this transmission is centered on the mechanical requirements of its intended racing environment.
Ball Spline Design and Traction Characteristics
The ball spline system is a central feature of the 062 SG1500. Rather than simply functioning as a conventional automatic transmission replacement, the unit is designed to address driveline bind and its effect on vehicle behavior.
Keyser states that greatly reducing driveline bind allows the rear suspension to move faster and smoother. According to the manufacturer, this can improve traction on dry slick race tracks.
For a racing vehicle, suspension movement and drivetrain behavior are closely connected. A drivetrain that introduces excessive bind can influence how the rear suspension responds when the vehicle is accelerating. The 062 SG1500 is therefore designed around a drivetrain approach that gives the suspension greater freedom to react.
This makes the transmission particularly relevant to racers who prioritize traction management, reduced rotating weight, and consistent chassis response.
Why This Transmission Is Different
The 062 SG1500 stands apart from conventional automatic transmissions because its primary design objective is not simply replacing an OEM transmission.
Many replacement transmissions emphasize compatibility with a particular vehicle, engine, bellhousing, electronic control system, or factory drivetrain. The 062 SG1500 instead belongs to a specialized racing category where weight, drivetrain behavior, and traction characteristics are major considerations.
Its second-generation aluminum ball spline design provides a combination of low weight and reduced driveline bind. Keyser specifically markets the transmission toward Late Model and Modified racers, making the intended application clear.
For a purpose-built racing vehicle, this specialized approach can be more relevant than the features found on a conventional street transmission.
Who This Transmission Is Best For
The Keyser Manufacturing Automatic Transmissions 062 SG1500 is best suited to professional and serious amateur racing applications, particularly Late Model and Modified race cars.
It may be appropriate for:
- Late Model racing builds
- Modified racing applications
- Race teams focused on traction optimization
- Builders seeking reduced rotating weight
- Racing applications where driveline bind is a concern
- Chassis setups operating on dry slick race tracks
It is not positioned as a conventional replacement transmission for everyday passenger vehicles. Buyers should therefore confirm that their racing chassis, drivetrain, and intended application are compatible with the Bert ball spline transmission design before ordering.

The technical information above focuses on the specifications and characteristics that Keyser publicly identifies for this specific transmission. Keyser’s official product page does not provide the full conventional specification set typically published for OEM-style transmissions, such as gear count, tailshaft length, input spline count, or fluid capacity. Those details have therefore not been invented or inferred.
Racing Performance and Practical Considerations
The 062 SG1500 is built around the principle that drivetrain efficiency involves more than simply transferring engine power through the transmission.
For racing vehicles, reducing rotating weight and minimizing driveline bind can influence how the chassis responds under acceleration. Keyser specifically connects the ball spline design with faster and smoother rear-suspension movement and improved traction on dry slick tracks.
Its 45.7-pound weight is another significant consideration for race-car builders. Weight reduction can be valuable when optimizing the overall vehicle, particularly when the transmission is part of a larger drivetrain and chassis setup.
However, this is a specialized racing component. It should be selected based on the requirements of the complete drivetrain and chassis rather than treated as a universal automatic transmission replacement.
Ordering and Application Considerations
When purchasing the Keyser Manufacturing Automatic Transmissions 062 SG1500, buyers should confirm that the intended application is compatible with the Bert aluminum ball spline transmission design.
The manufacturer specifically identifies the unit for Late Model and Modified racers, so application-specific verification is important before purchase.
The available manufacturer information confirms the product identity, second-generation ball spline design, weight, and intended racing market. However, it does not provide enough information to establish universal compatibility with a particular vehicle or drivetrain without additional application details.
Customers building a specialized racing drivetrain can also compare this unit with other performance transmissions, racing transmissions, and drivetrain components to select equipment appropriate for their chassis and competition requirements.
