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.

JSD-Dealer Lette2018-12-03. Service bulletin. Dealer Letter: August 13, 2018. ? A section has been added which clarifies the process for obtaining DSPM approval for out-of-warranty CVT assembly replacement. ? Clarification has been added to the parts ordering process for CVT assembly replacement to highlight that the CVT assembly parts ordering process is applicable regardless of warranty coverage. ? The descriptions for OpCodes JSD021 and JSD020 have been clarified. Toyota previously announced Special Service Campaign J0D, which involved performing a software update to the CVT control software to address the condition described below. Following the completion of the software update in Special Service Campaign J0D, Toyota dealers received reports from some customers stating that the vehicle experienced harsh shifting and/or abnormal engine RPM between shifts. These issues occurred close to the completion date of the campaign and/or within relatively low mileage from the completion of the campaign remedy, prompting Toyota to suspend Special Service Campaign J0D. Toyota has now identified the cause of these issues and has developed a new remedy. Special Service Campaign JSD, which replaces Special Service Campaign J0D, applies this new remedy. Owners of all vehicles previously involved in Special Service Campaign J0D, including those who have previously completed Special Service Campaign J0D, are requested to visit an authorized Toyota dealer to have Special Service Campaign JSD performed.
