Kia bulletin TSB_TRA096
Kia filed this with NHTSA as a service bulletin dated Aug 20, 2021, received Aug 25, 2021, about the power train. It names 1 model year (2016). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationTECHNICAL SERVICE BULLETIN: 8AT (A8LR1-SBW) SOLENOID VALVE REPLACEMENT AND TCU LOGIC IMPROVEMENT - This bulletin provides the procedure to replace two (2) solenoid valves (35R and 4&OD) and improve the gear shift logic of the Transmission Control Unit (TCU) on some 2015-2016MY K900 (KH) vehicles, equipped with Tau 5.0L engine and 8-speed automatic transmission w/Shift-By-Wire (A8LR1-SBW), which may exhibit symptoms of abnormal shift shock during an upshift (2nd-->3rd, 3rd-->4th, 4th-->5th). This condition occurs on vehicles with mileage over 12,000 miles and may be due to possible premature wear of the solenoid valve. To correct this concern, replace the 35R and 4&O/D solenoid valves with added “Hâ€� ventilation port, perform TCU relearn, and, if applicable, apply the improved logic to the Transmission system using the KDS ECU Upgrade function as described in this bulletin.

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia TSB_TRA096 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the TSB_TRA096 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does TSB_TRA096 cover?
The manufacturer filed it against 1 model year: 2016 Kia K900. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
