A transmission control valve in some of these vehicles may be susceptible to excess wear over time, resulting in a gradual loss of pressure within the valve that can cause harsh shifting. In rare cases, the wheels may experience a momentary lock up. If the wheels lock-up momentarily while driving, there is increased risk of a crash. Dealers will install new transmission control module software that will monitor valve performance and detect excess wear approximately 10,000 miles (16,000 km) before a wheel lock up condition could occur. Once detected, the transmission will be limited to fifth gear, preventing the possibility of a wheel lock up condition, which occurs in a downshift from eighth gear. A service engine light and reduced propulsion message will also display in the instrument panel.
