Service bulletin TI-64-12
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.

| 122-X7S6C-06 | 2017-08-01. Service bulletin. Concerns: Electric change-over valves Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. There is the possibility that electric change-over valves, which may be susceptible to the ingress of moisture due to insufficient sealing, were installed in the affected vehicles. This can cause the change-over valves to malfunction over time. As a result, control over the closing valves in the clutch cooling system (PDK) and gear wheel set (PDK and manual transmission) may be impaired. In extreme driving situations (e.g. race starts, high ambient temperature, frequent gear changes), the transmission or clutch could overheat. |
