Owners of some 2008-13 General Motors cars and SUVs may come into your store with a complaint of a transmission leak.
According to GM, the leakage issue is most obvious on 6T30, 6T40, 6T45 and 6T50 automatics and typically is the result of a worn torque converter seal.
Installing a new-design seal made of a more durable material, part No. 24256953, should eliminate the leakage concern.
Vehicles that are susceptible to the condition are as follows:
- 2008-13 Chevy Malibu;
- 2010-13 Buick LaCross, Chevy Equinox and GMC Terrain;
- 2011-13 Buick Regal and Chevy Cruze; and
- 2012-13 Buick Verano and Chevy Captiva Sport and Sonic.
