A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

Transmission warning may appear in instrument cluster. After ignition cycle, the warning message is no longer present. DTC P074100 (Torque Converter Clutch Circuit Performance) or ?Stuck Off? is stored in transmission control module (TCM). The fault occurs with ATF temperature below 60o C. Check for this temperature range in the extended environmental conditions of the diagnosis protocol. This TSB only applies if the ATF level is correct and there are no leaks.
A371433 2029305-2017-11-08. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Supersedes Technical Service Bulletin Group 37 number 13-96 dated March 4, 2013. Customer may report harsh downshifts while braking or harsh 1-2 upshift under acceleration. Further transmission control module (TCM), J217 (address word 02), software calibration to improve shift concerns.
A971442 2036764-2017-11-08. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 97 number 14-41 dated March 18, 2014. The MIL is on. Vehicle will not start. DTC P068A00 is stored in the engine control module (ECM), J623 (address word 01). Numerous unrelated DTCs are also stored in the system, including: P056200, P057100, P068700, P068A00, P162400, P190C00, U010000, U010100, U012100, U014600, U015500, U021200, U101100, U102600, U111100, U111300, U140000, VAG00003, VAG00185, VAG00263, VAG00317, VAG00384, VAG00446, VAG00456, VAG00457, VAG00466, VAG00473, VAG00532, VAG00565, VAG00591, VAG00714, VAG00819, VAG00955, VAG01217, VAG01299, VAG01314, VAG01315, VAG01317, VAG01320, VAG01330, VAG01331, VAG01332, VAG01334, VAG01333, VAG01336, VAG01705, VAG01964, VAG02067, VAG02072, VAG02095, VAG02103, VAG02203, VAG02214, VAG02635, VAG02812, VAG02874, VAG03041, VAG03157, VAG03166, VAG03220, VAG03278, and/or VAG03531. The motronic engine control module power supply relay, J271, is not functioning properly. Because the J271 relay controls battery voltage (Terminal 30) via a ground signal sent from the ECM, numerous faults can occur in multiple control modules when it is not functioning properly.
