GROUP MODEL TRA 2016-2020MY Optima (JFa) w/1.6L T-GDI and 7DCT NUMBER DATE 098 August 2021 TECHNICAL SERVICE BULLETIN SUBJECT: 7-SPEED DUAL CLUTCH TRANSMISSION (DCT) ANTI-JUDDER LOGIC IMPROVEMENT This bulletin provides the procedure to update the software logic of the Dual Clutch Transmission (DCT) system on some 2016-2020MY Optima (JFa) vehicles produced from August 28, 2015 through June 1, 2020, equipped with Gamma 1.6L T-GDI engine and 7-speed DCT, which might exhibit clutch judder when accelerating from a stop. If the vehicle body vibrates without the steering wheel shuddering when performing creep driving test (driving the vehicle up to 3 mph), the vehicle is exhibiting clutch judder. Follow the flowchart on page 2 as needed to apply the improved logic to the ‘A/T’ system using the KDS ECU Upgrade function as described in this bulletin. For confirmation that the latest reflash has been applied to a vehicle you are working on, verify the ROM ID using the table on page 3 of this bulletin.
