The F1CJA/W1CJA transaxles are CVT units featuring INVECS III technology and were used in the Seventh Generation Lancer, Second Generation Outlander and early Third Generation Outlander vehicles. They are the same basic transmission with the W1CJA having a transfer case added for all-wheel drive applications. Some vehicles have a tiptronic gear selector, where the transmissions simulates having six distinct gear ratios.
The transaxles are manufactured by Jatco who identifies them as the JF011 or CVT2 and are designed for medium torque applications (up to 250Nm). They have been used in a variety of applications in vehicles from Suzuki, Nissan, Jeep and Dodge.
The transaxles employ an electronically controlled torque converter (to assist in take off), forward and reverse clutches, reverse planetary gear set, two pulleys/variators and a steel reinforced push belt. Ratios are controlled using a stepper motor, ratio control valve, secondary valve and secondary pressure solenoid which change the effective diameter of the pulleys thus changing the ratio.
