Service bulletin SU2302
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
Coolant leaks at the transmission cooler fittings on the radiator are occurring due to deformation of the gasket used to seal off the transmission cooler. This deformation is caused from transmission oil wicking through the thread adapter threads and exposing the lower portion of the gasket to transmission oil. Re-configure hydraulic interface between the transmission cooler lines and the transmission oil cooler.
