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.

PS-4412016-09-14. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). HARSH UPSHIFT AFTER PERFORMING TSB TRA 058/SA208 - KMA HAS RECENTLY IDENTIFIED AN INCREASE IN TECHLINE CASES WITH A COMPLAINT RELATED TO “A/T UP-SHIFTING HARD” IN MOST GEARS. FURTHER INVESTIGATION HAS REVEALED THAT MOST OF THESE OCCURRED AFTER PERFORMING TSB TRA 058 / SA208 USING MANUAL MODE AND POSSIBLY HAVING, INADVERTENTLY, ENTERED AN INCORRECT PCM/TCM PART NUMBER. IN SOME CASES, TRANSAXLES HAVE ALREADY BEEN REPLACED WITHOUT CONDITION IMPROVEMENT. PRIOR TO REPLACING A TRANSAXLE FOR A SIMILAR CUSTOMER CONCERN, CHECK CURRENT ROM ID NUMBER USING GDS/KDS. NOTE: PAY CLOSE ATTENTION TO THE WHEEL SIZE REFERENCE INFORMATION ASSOCIATED WITH PCM/TCM PART NUMBERS.

The summaries are NHTSA's. Each bulletin's page links NHTSA's copy of the manufacturer's document.
