When accelerating on an incline or hill or trying to pass traffic on the interstate the truck hesitates or stutters. This seems to happen when applying light acceleration. It almost feels like the transmission is having difficulty finding the correct gear. This is apparent to both driver and passengers. This has occurred since the truck was new and seems to be getting worse. The truck currently has 13,000 miles.

When accelerating at a very slow speed the engine seems to misfire or sputter and then the engine increases rpm and the truck accelerates as expected. Overall the engine lacks power and there is loud clicking sound that originates from the engine compartment area. I spoke with service manager at gmc and i was told that clicking sound was normal and gmc was working on the acceleration problem.
