2001 GMC Sierra 2500 HD SL 8.1L Valve body
This truck has very low mileage and is driven to and from work(approx. 7 mile) daily. Upon initial start-up, no problem. After the engine gets to operating temp though, if re-started, a loud clunk is noticed in the valve body of the Allison 1000 trans. No DTC'...
