Is there a difference between manual and automatic transmission fluid?
Is there a difference between manual and automatic transmission fluid? Well, in some cases yes. But many, many manual transmissions–of course there aren’t that many of them left anymore–but many of them use automatic transmission fluid. This is so that they’ll shift easier, because the old-school, really thick, gooey lubricant that they used in manual transmissions often made them very difficult to shift at colder temperatures. So today, you have to look at the owner’s manual, and don’t be surprised if it tells you to use automatic transmission fluid in your manual transmission.
