Tap a recall to see the problem, the risk and the fix.

Power train:automatic transmission:cooling unit and linesSep 26, 2007 · NHTSA campaign 07V453000 · 1,497 vehicles

Problem: On certain sport utility vehicles equipped with the 4.6l engine and 6r transmission, the bolt securing the transmission oil cooler line fittings at the transmission may not have been sufficiently torqued during vehicle assembly. As a result, the bolt may loosen and the transmission oil cooler lines may disengage from the transmission, causing a transmission fluid leak.

Risk: If leaking transmission fluid contacts the catalytic converter, it may pose a risk of fire.

Fix: Dealers will inspect and have the transmission cooler line attachment bolt tightened free of charge. The recall began on august 30, 2007. Owners may contact ford at 1-800-392-3673.
