I have Mopar ATF 4+ fluid in my transmission right now. I need to top off the fluid--can I use another brand of ATF 4+ fluid like a Valvoline?
Sure you can. They all mix. Just make sure it’s the 4+. It’s the same design; they all mix perfectly fine. There is no problem in doing that at all. If you would like to have a technician perform this oil change for you, they can provide the oil and come to your home or office to get this done.
