My parents just purchased a 2011 silverado 4.8 to pull their 2 horse trailer. As stated it has the 4.8 engine (no active fuel management bs to the extent of my knowledge) and what was an unlabled 4 speed (on the listing at least). My questions are is this 4 speed a variant of the 4l60e, if not then what exactly is it and what things should we look out for about these trucks by way of problems?
It only had 74k miles on it when purchased.
