If it for the auto, just be sure it ATF+4 rated. Don't use ATF+3 in a 48re.

Amsoil & Royal Purple are different companies.

I used Amsoil Universal Synthetic in my '92 diesel always towing and had no problems at all. I plan on using it again in my 2004.5 when it comes time for its first trans. service.
