Service bulletin 21-037-14
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.

NHTSA's summary
66RFE Transmission Slip Under High Engine Load And Premature Wear This bulletin involves inspecting the torque converter build date and if necessary, replacing the torque converter. A small number of torque converters were manufactured with the oil grooves on the internal friction discs too wide. This may result in the transmission slipping under heavy loads causing premature wear.
