Some specifics around gearbox from my link above , Source: Toyota US pressroom.
For Manual Transmission (MT), the shape of the shift lever is optimized for smooth, enjoyable shifting, whether you’re moving from 2nd to 3rd or downshifting from 5th to 4th. Additionally, a carbon synchronizer was added to improve shifting into 4th gear. The MT uses new low-viscosity oil and bearings for smooth shifting operability with the higher torque output of the 2.4L boxer engine.
For the Automatic Transmission (AT), when in Sport mode, the AT senses brake and accelerator operation and vehicle behavior to automatically shift into the optimal gear, bringing drivers the control they want. Additional clutch discs and a new high-capacity torque converter allow for smooth delivery of the engine’s added power.
