I have heard mixed reviews regarding Amsoil in the 68rfe. It was enough to turn me off. If you decide not to use Amsoil, then it is really easy. You just need to be ready for a wide stream of oil once you unbolt the pan. MagHytec comes with new fasteners and allen keys to fit. Bolt it up, refill lost fluid (mine was about 9 liters, I think that is around 8 quarts) and then fire it up. I checked for leaks, checked the level, then went on a short drive to warm things up. Got back and checked the level again, and had another quick look for leaks. Done!
