It is manufactured by Tremec, a company known for producing durable, high-performance gearboxes. The TR 6060 is designed to handle high horsepower and torque, making it ideal for performance-oriented applications.
Key Features of the TR 6060
High Torque Capacity: The TR 6060 can handle up to 600 lb-ft of torque, making it capable of supporting some of the most powerful engines.
Six Gears: The transmission features six forward gears, providing an optimal balance between acceleration and fuel efficiency.
Close-Ratio Gearing: The TR 6060 has a close-ratio gear setup, which is ideal for maintaining performance at high RPMs and ensuring smooth shifts during aggressive driving.
Twin-Tapered Roller Bearings: These help reduce friction and improve shifting performance, enhancing the overall driving experience.
Applications of the TR 6060
- Sports Cars: As mentioned earlier, the TR 6060 is found in high-performance sports cars and is built for enthusiasts who demand the best in terms of shifting performance and power handling.
- Custom Builds: Many performance enthusiasts choose to swap their vehicles’ factory transmissions for the TR 6060 to enhance their driving experience.
What Is The T670 Transmission?
On the other hand, the T670 is a manual transmission that is commonly used in heavy-duty trucks, such as long-haul freight vehicles. Like the TR 6060, the T670 is manufactured by Tremec, but it is designed with a focus on reliability, ease of operation, and long-distance performance. It is not intended for high-performance sports applications, but it is built to handle the heavy-duty demands of commercial vehicles.
Key Features of the T670
Heavy-Duty Build: The T670 is constructed with the strength and durability needed to withstand the constant demands of long-haul trucking.
Low-gear Ratios: The T670 transmission comes with a variety of gear ratios that allow for optimal torque delivery, especially at low speeds, which is critical for truckers.
Ease of Operation: The T670 is engineered for smoother shifting and ease of use, which is important for truck drivers who spend long hours on the road.
Heavy Load Capacity: The T670 can handle higher loads compared to the TR 6060, making it more suited for applications that require moving heavy freight.
Applications of the T670
- Commercial Trucks: The T670 is commonly found in large rigs and long-haul trucks, where efficiency, durability, and load-bearing capacity are the priorities.
- Fleet Operations: Many fleet operations choose the T670 for its reputation for reliability in daily commercial use.
Comparing The TR 6060 And T670: Key Differences
Purpose and Application
- TR 6060: The TR 6060 is primarily built for high-performance sports cars and custom applications where power and shifting performance are paramount.
- T670: The T670 is built for heavy-duty applications like long-haul trucking, where reliability, load-bearing capacity, and fuel efficiency are crucial.
Torque Capacity
- TR 6060: The TR 6060 can handle up to 600 lb-ft of torque, which makes it suitable for high-performance vehicles but not necessarily for heavy-duty trucks.
- T670: The T670 can handle far more torque, often exceeding 1,200 lb-ft, which is necessary for moving massive loads.
Gear Ratios
- TR 6060: The TR 6060 offers close-ratio gears, which means the gear steps are closer together. This is optimal for performance driving, where you want smooth acceleration and rapid shifts.
- T670: The T670 offers a wider range of gear ratios, designed for pulling heavy loads and maintaining steady speed at lower RPMs for long periods.
Durability and Maintenance
- TR 6060: While the TR 6060 is durable for sports car use, it requires more maintenance and care, especially given the high-performance nature of the vehicles it’s used in. Heavy or aggressive driving can lead to more frequent repairs.
- T670: The T670 is built to endure much harsher conditions, with heavy-duty components that require less frequent maintenance, making it ideal for long-haul trucking where downtime needs to be minimized.
Shifting Experience
- TR 6060: The TR 6060 is known for its smooth and fast shifting performance, designed for the spirited driver. The engagement is quick, and the gears lock in place with precision, offering a highly enjoyable driving experience.
- T670: The T670 offers more deliberate shifting, optimized for commercial trucking, where smooth engagement and ease of operation are necessary for comfort during long shifts on the road.
Which Transmission Is Better For You?
If You Drive a High-Performance Sports Car
If you are an enthusiast of performance cars like the Dodge Viper or Chevy Camaro ZL1, the TR 6060 is the better choice for you. It offers a precise shifting experience, high torque handling, and optimal performance, making it the perfect transmission for cars that are designed to provide speed, agility, and power.
