Hello,

It sounds normal for an automatic transmission, it has an ability to engine brake as well. If it brakes a lot faster than it should, then the source of your issues can be something other than engine or transmission, seized brakes or a bad wheel bearing could result in a similar problem. Check that all 4 wheels spin freely, the brake fluid looks clean, and all the calipers look solid with no tears in the seals.

Hope this helps and best of luck!
