What's the 2004 Chevy Impala transmission fluid capacity?

Regardless of engine configuration, eacH2004Chevrolet Impala comes with either A4 speed 4T65-E or 4 speed 4T65-E-HD transmission, both of which have the same capacity. You'll need an initial fill of 7.4 quarts, whereas the total fill level is 13.4 quarts. You'll see that the amount of fluid You'll be changing is just over half of the total amount. It's important that You change Your transmission fluid every 30,000 to 40,000 miles, and inspect Your levels in between -- low trans fluid levels or broken down trans fluid are the leading causes of an overheated transmission, which can potentially total Your transmission. Since it's one of the most expensive replacements You can muster on a vehicle, the cost of a new transmission will often exceed the value of a vehicle that's almost two decades old.
