CLUTCH
Increased torque
transmission capacity
The clutch cover set load has been increased.
Torsional spring tension has been reduced to reduce NVH.
MT
Improved operability
A ball-type synchromesh mechanism has been adopted.
A triple synchronizer mechanism has been adopted for 1GR, 2GR and 3GR.
Bushings for the control rod have been adopted.
Improved driveability
In order to obtain more power from the engine, the total gear ratio has been reduced in speed
and set in a cross pattern.
To improve drivetrain rigidity, a closed section power plant frame (PPF) has been adopted.
Improved fuel economy Six-speed Y16M-D manual transmission has been adopted.
Improved marketability Six-speed Y16M-D manual transmission has been adopted.
Improved reliability A double engagement prevention mechanism (interlock mechanism) has been adopted.
Mis-shift prevention A reverse lockout mechanism has been adopted.
AT
Superior shift quality
Direct electronic shift control by duty-cycle solenoids has been adopted.
Feedback control system has been adopted.
Centrifugal balance clutch chamber has been adopted.
A plate-type clutch pack replaces the band brake in the 2-4 brake.
Shifting assist at high engine speeds has been achieved due to adoption of an engine-
transmission total control system.
High efficiency,
compactness, lightweight
A miniature trochoid gear oil pump with torque converter direct drive has been adopted.
Due to complete electronic control of clutch engagement and release pressure, the forward
one-way and overrunning clutches have been eliminated.
Due to the adoption of direct electronic clutch pressure control (direct electronic shift control),
the accumulators have been eliminated.
Improved reliability,
reduced NVH (noise,
vibration, and harshness)
A pleat type oil strainer with fine mesh has been adopted.
A highly rigid transmission case has been adopted.
Improved driveability
To improve drivetrain rigidity, a closed section power plant frame (PPF) has been adopted.
A control feature for climbing/descending hills has been adopted, improving driveability when
climbing/descending.
Improved marketability
The Sport AT has been adopted. With this feature up and downshifting can be performed with
either the shift control switch on the steering wheel or with the one-touch operation of the
selector lever.
