Owners of some 2008-13 General Motors cars and SUVs built before Feb. 1, 2013, may come into your store with a complaint of transmission fluid leakage.
According to GM, the leakage issue is most prominent on 6T30, 6T40, 6T45 and 6T50 automatics, and is usually the result of a worn torque converter seal. Installing a new-design seal made of a more robust material, Part No. 24256953, should eliminate the leakage concern in short order.
Vehicles that are most susceptible to the problem and can benefit from the upgraded converter seal include 2008-13 Chevy Malibus; 2010-13 Buick LaCrosses, Chevy Equinox and GMC Terrains; 2011-13 Buick Regals and Chevy Cruzes; and 2012-13 Buick Veranos and Chevy Captiva Sports and Sonics.
