Rich, I used Mobil 1 synthetic ATF when I changed my tranny fluid. To be honest I have heard good and bad about Royal Purple products, enough bad to keep me away. On the other hand I have heard many good things about Amsoil products. And for those who might ask, I have read not to use synthetic in the diff.
