According to a website I was looking at : For a 2007 Ford Mustang , 4.0 liter V6 engine : A 5 speed manual transmission is ( 17 city / 25 highway ) An automatic transmission is ( 16 city / 24 highway ) Miles per U.S. gallon
THere is no dipstick on a 2005-2007 Mustang since Ford considereds the transmission sealed it wont need fluid added unless it has a leak or you are changing the fluid.
The transmission fluid filler is located in the back of the engine compartment on the 2007 Accent manual transmission. You fill it by removing the dipstick.
It's a manual transmission, it doesn't need fluid at all.
Automatic transmission does have a pump and filter. A manual does not.
