Theory Of Operation
WARNING: This page is about a different car, the 2009 Dodge Caliber. However, it is still accessible from the selected car via links, so may be relevant.
This DTC will set to indicate an overheating transmission or engine cooling system. Extended transmission operation above 115°C (240°F) will reduce the durability of the transmission and should be avoided. Correcting the cooling system operation or installing an additional transmission oil cooler will improve transmission durability, especially under extreme conditions such as city/construction stop and go traffic, trailer towing, aggressive driving in low gear, or operation in mountainous areas.
