I want to change the transmission fluid on my 2005 5.4L this weekend. I plan to drop the pan, change the filter, and use this guide
to flush the fluid. It's my first time changing ATF, but I do all of my other maintenance and don't think it will be a big deal. However, I have the following questions.
1. What transmission do I have and how many quarts of ATF does it hold? I believe it's the 4R75E, but there's nothing I've found on the door or under the hood to confirm.
2. Is it worth it to switch to AMSOIL? I do very little towing, mostly city driving. My gut says that at 2 to 3 times the price, it's not worth it.
3. If I don't switch to AMSOIL, do I go with MERCON or MERCON V?
Yes I know this has all been talked about, but when I searched, I got a lot of conflicting results. Thanks.
