What would cause your car to hesitate before it shifts into gear The car is an automatic Oldsmobile?
low trans fluid level.
there isn't a difference cause theres no such thing as a automatic or manual engine. there is such thing as a manual transmission aka trans. and a automatic trans. the automatic shifts by hydrolic pressure that increases when acclurating. and a manual trans the person driving the vehical shifts the gears with a lever. i hope that's what you wanted to know.
