Faulty transmission control valve can fail and cause rear wheels to lock up, increasing risk of crash, according to General Motors.

General Motors Co. has recalled nearly 462,000 pickups and SUVs equipped with Duramax turbo-diesel engines for transmission control valves that are susceptible to excess wear over time, resulting in harsh shifting, or in rare cases can cause the rear wheels to lock up while driving, according to the National Highway Traffic Safety Administration.

Affected vehicles include the Chevy Silverado and Tahoe, GMC Sierra and Yukon ... use a different automatic transmission and aren’t caught up in the recall. Fortunately for GM’s accountants, the fix doesn’t involve replacing the entire gearbox.
