TR-9080 (Original Equipment)
Crafted as the exclusive transmission for the 2020 Chevrolet Corvette Stingray, the TR-9080 boasts dual clutches that engage and release with flawless computer-controlled synchronization, allowing for gear shifts in under 100 milliseconds without compromising torque delivery.
This 8-speed dual-clutch transmission is tailored for extreme performance, offering either a fixed-bias mechanical limited-slip differential (mLSD) or an electro-hydraulically controlled limited-slip differential (eLSD) with active selection of the locking ratio, ensuring optimal traction and handling.
Enthusiasts can engage paddle shifters to personalize gear selection, while the performance shift algorithms are thoughtfully designed to sense spirited driving and maintain lower gears for heightened throttle response. TREMEC’s cutting-edge wet clutch technology features active thermal management, robust proprietary friction plates, and exceptional versatility to accommodate various engine applications, Elevating Performance™ to new heights.
Performance With an automated dual clutch transmission (DCT), engine output is coupled to either of two transmission input shafts. Each clutch functions as both a launch clutch and dynamic shifting clutch, enabling clutch-to-clutch shifts without torque interruption, giving the driver continuous transmission of torque and power to the wheel. The bespoke TR-9080 DCT provides lightning-fast shifts in less than 100 milliseconds from best-in-class controls software, solenoids and hydraulics.
Control Solutions The DCT is controlled with a high-performance, 32-bit transmission control unit. All systems - including hardware such as low-leak solenoid valves and electro-hydraulic actuation systems to control systems and software - were internally developed by TREMEC for maximum performance. To create the optimal performance during launch and shifting, TREMEC developed advanced algorithms capable of calculating torque targets in real time. Fast and repeatable torque control is achieved through model-based control strategies, using detailed knowledge and characterization of all transmission subsystems and components.
Mechanical Design The in-house designed concentric wet dual clutch offers high torque and thermal capacity in a compact package. This innovative wet clutch has TREMEC-proprietary optimized friction materials with the ability to cool the clutches only when needed, boosting efficiency.
TREMEC’s vertically integrated manufacturing allows customized gear design and development for tight tolerances and famously robust durability. Power-honed synchro/speed gears give a quiet ride without sacrificing performance.
The TREMEC-designed limited slip differentials feature spiral bevel designs that allow the entire transaxle to use a single fluid, allowing mass savings from a single oil cooler, pump, oil sump and filtration system. The force-cooled electro-hydraulically controlled limited slip differential (eLSD) is integrated with the transmission control system to allow fast responsiveness and fine control of the locking ratio and provides the ability to withstand ® Torque Transfer Solutions® sustained high-performance driving.
