What's the 2015 Dodge Charger transmission fluid type?

The 2015 Dodge Charger uses a Dexron ViATF automatic transmission fluid, or compatible. An example of one You can buy is Castrol's 15A9FA, which runs for around $10 a quart at Advance Auto Parts. You typically won't go through a lot of ATF; it's good to check when the engine's warm, by pulling up the dipstick and seeing if the fluid is between the MIN and MAX marks. If it's not, You'll want to use a funnel to dump some fluid into the same orifice as the dipstick goes into. Be careful not to overfill, as that can be as problematic as a low condition here.
