16038 - Customer Satisfaction. Certain vehicles, equipped with an 8 speed automatic transmission and an extra capacity cooling system, may have a condition in which the transmission oil cooler (TOC) lines come in contact with the body studs for the outer quarter panel reinforcement. Over time this contact may wear a hole through the line causing a fluid leak. It is possible that the leak may not be visible, but could lead to illumination of the malfunction indicator lamp, rough/irregular shifts, slipping, and, eventually, complete loss of propulsion. Dealers will install a protective sleeve to the TOC line.
