The engineering team modified an existing transmission housing, driveshaft and gear set and removed elements that were not required, such as the acoustic package, which reduced weight. At the heart of the transmission is a newly engineered large diameter clutch with a reinforced diaphragm spring. With a larger friction area and a stronger spring, this new component has the high-performance capability appropriate for use with the GR Supra’s high-torque engine.
The newly developed 6-speed manual gearbox also features an intelligent Manual Transmission (iMT) programmed with new software that prioritizes sporty performance. When upshifting, the parameters are tuned to optimize engine torque at the moment of clutch engagement and release; on downshifts, the software has been fine-tuned for consistent performance. The iMT is set as the default but, if the driver prefers, it can be switched off in Sport mode.
To avoid a sluggish take-off and a low in-gear acceleration feel, the final drive ratio has been shortened, from 3.15 (in the GR Supra automatic) to 3.46 (in the GR Supra MT). The result is response and gearing appropriate for sports car performance.
