Transmission Oil Cooler Lines

WARNING: This page is about a different car, the 2017 GMC Acadia. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

The transmission oil cooler system uses quick connect fittings throughout the system. Use a special tool to disconnect these quick connect fittings. Removing the transmission oil cooler lines without this tool will result in damage to the radiator, the transmission, and the transmission oil cooler caused by mixing the transmission oil and coolant or due to transmission oil loss.

The transmission oil cooler lines use quick connect fittings on the transmission oil cooler lines near the A/C condenser. The quick connect fittings must be removed using a special tool. The transmission oil cooler is an oil-to-air heat exchanger located above the A/C condenser. The transmission oil temperature is regulated by the temperature of the air passing over the heat exchanger. Lines from the transmission bring oil pumped at a high pressure to the cooler and back to the transmission. This provides uninterrupted transmission oil flow for low ambient temperature conditions.
