OUTLINE

• A hydraulic clutch control mechanism is used.
• 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.
• To improve drivetrain rigidity, a closed section power plant frame (PPF) has been adopted.
• A double engagement prevention mechanism (interlock mechanism) has been adopted.
• A cam-type reverse lock-out mechanism has been adopted.
• A triple synchronizer mechanism has been adopted for 1GR, 2GR, 3GR and 4GR.
• Low friction bushings for the shift rod have been adopted.
• 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.
• Six-speed P66M-D manual transmission has been adopted.
• Six-speed P66M-D manual transmission has been adopted.
• A double engagement prevention mechanism (interlock mechanism) has been adopted.
• A push-type reverse lockout mechanism has been adopted.
• Six-speed SJ6A-EL automatic transmission has been adopted.
• 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.
• Torque reduction control and line pressure control has been adopted.
• Shift learning control has been adopted.
• 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.
