What's wrong?
The affected 2014-2015 Chevrolet Silverado, Yukon, Tahoe, Suburban, and Sierra vehicles use a transmission oil cooler line to move transmission fluid between the 6-Speed Automatic Transmission and the cooling system. That fluid carries heat away from the transmission and helps the internal parts stay lubricated while the vehicle shifts and pulls under load.
On these vehicles, the transmission oil cooler line is not securely seated in its fitting. A loose line can let transmission fluid escape instead of staying in the closed system. Once fluid is lost, the transmission loses cooling and lubrication it needs to operate correctly.
There is no warning sign before failure. An owner should not count on a dashboard light, noise, or shift feel to confirm the line is coming loose.
Who's affected?
Spans pickup and SUV nameplates across the 2014 and 2015 model years, all tied to the automatic transmission cooling lines.

What's the safety risk?
A transmission oil cooler line that is not securely seated can leak transmission oil from the fitting. If that oil reaches a hot surface, it can start a vehicle fire.

What happens at the repair
