Clutch

CLUTCH

Improved operability 

• A hydraulic clutch control mechanism is used.

5-SPEED MT [M15M-D]

Improved operability

• A triple synchronizer mechanism has been adopted for 1GR and 2GR.

• A double synchronizer mechanism has been adopted for 3GR.

• A carbon synchronizer mechanism has been adopted for 4GR.

• Low friction bushings have been adopted for the shift rod supporting area.

• With the adoption of a low spring constant and high set load type 1-2 return spring, a secure 

neutral position is assured.

Improved driveability

• To improve drivetrain rigidity, a closed section power plant frame (PPF) has been adopted.

Improved reliability

• A double engagement prevention mechanism (interlock mechanism) has been adopted.

Mis-shift prevention

• A cam-type reverse lock-out mechanism has been adopted.

6-SP

EED MT [P66M-D]

Improved operability

• A triple synchronizer mechanism has been adopted for 1GR, 2GR, 3GR and 4GR.

• Low friction bushings for the shift rod have been adopted.

Improved driveability

• In order to obtain more power from the engine, the total gear ratio has been set lower and the 

difference between each gear ratio has been set closer.

• To improve drivetrain rigidity, the power plant frame (PPF) has been adopted.

Improved fuel economy

• Six-speed P66M-D manual transmission has been adopted.

Improved marketability

• Six-speed P66M-D manual transmission has been adopted.

Improved reliability

• A double engagement prevention mechanism (interlock mechanism) has been adopted.

Mis-shift prevention

• A push-type reverse lockout mechanism has been adopted.

6-SPEED AT [SJ6A-EL]

Improved fuel economy

• Six-speed SJ6A-EL automatic transmission has been adopted.

Improved marketability

• Six-speed SJ6A-EL automatic transmission has been adopted.

• 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.

• A 5-6 shift inhibit control has been adopted for rapid engine warming.

Superior shift quality

• Torque reduction control and line pressure control has been adopted.

• Shift learning control has been adopted.

Improved driveability

• To improve drivetrain rigidity, power plant frame (PPF) has been adopted.

• A control feature for climbing/descending hills has been adopted, improving driveability when 

climbing/descending.
