As Cobra Kai wrote: "Chevron has the exact same specs as the Havoline". Not only do they have the same specs, Chevron makes and ownsHavoline.
I'm a new 07' GT owner and haven't noticed a shifting problem, but I wonder if Mercon V might be a "cure". Mercon V is a syn blend if you are insisting on a synthetic. Some brands are group V and group II blends. It sure cured shifting problems in a friend's Toyota transmission. (rice).
