Extreme Performance

TREMEC dual-clutch technology has transformed automated manual transmissions with the new TR-9070 DCT. The innovative transmission provides extreme performance with 900 Nm torque capacity and lightning fast shift transitions of less than one-tenth of a second.

Depending on the requirements of the situation and mode, the fun-to-drive 7-speed dual-clutch transmission thinks, learns and performs - whether it be normal driving, sporty driving, drag racing or track racing.

The main objective of the DCT layout is to make the transmission as light and compact as possible. To this aim, all hydraulics, sensors and clutches are fully integrated into the gearbox. A successful light-weighting strategy incorporates die cast aluminum housings, a compact gear-train arrangement, hollow shafts, a plastic sump pan, and more.

Control packages
The DCT is controlled with a high-performance, 32-bit transmission control unit. The TCU controls all functions of the gearbox, including the hydraulic system, the two clutches, the eight gears (first through seventh and reverse) and the park lock. All systems and subsystems - including hardware such as low-leak solenoids and electro-hydraulic actuation systems, to control systems and software - were internally developed for maximum performance.

Software solution
In order to create the desired feel during launch and shifting, TREMEC engineers developed advanced algorithms to calculate torque targets, in real time. An underlying torque chain converts the targets into an electrical target for the control valves, making torque control fast and repeatable.

Clutch design
The clutch design marries the benefits of wet and dry clutch technologies into a hybrid design. A highly efficient wet clutch system with optimized friction materials have the ability to cool the clutches with lubrication individually and only when needed. The end result is a controllable thermal load and much lower drag.
