TECHNICAL SERVICE BULLETIN
SUBJECT:
TRANSMISSION LOGIC IMPROVEMENT
This bulletin provides the procedure to optimize the logic of the Transmission Control Unit
(TCU) on 2017-2018MY Soul (PS) and Forte (YDm) and 2016-2018MY Optima (JFa) vehicles
equipped with 1.6T GDI that have one of the following three components replaced:



Dual Clutch Transmission (DCT) assembly
Transmission Control Unit (TCU)
Double Clutch Set
The friction material of the double clutch set has been changed and a TCU logic optimization
must be performed in order to prevent initial shift shock. To prevent this concern, apply the
optimized logic to the TCU 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.
 NOTICE
If parts must be ordered, be sure to order parts using the old part numbers listed in
the tables on page 2-3, if available. If old parts are no longer available, new
supersession parts may be ordered.

upgrade.
All ECU upgrades must be done with the ignition key in the ‘ON’ position.
Be careful not to disconnect the VCI-II connected to the vehicle during the ECU
upgrade procedure.
DO NOT start the engine during ECU upgrade.
DO NOT turn the ignition key ‘OFF’ or interrupt the power supply during ECU
upgrade.
When the ECU upgrade is completed, turn the ignition ‘OFF’ and wait 10 seconds
before starting the engine.
ONLY use approved ECU upgrade software designated for the correct model,
year.
 NOTICE
Before attempting an ECU upgrade on any Kia model, make sure to first determine
whether the particular model is equipped with an immobilizer security system.
Failure to follow proper procedures may cause the PCM to become inoperative after
the upgrade and any claims associated with this repair may be subject to
chargeback.
