Greetings,
I am about to do a transmission fluid exchange on my 5.7 Liter 2008. Last time I used Amsoil ASL (low vis, WS compatible). Now they have changed names on their fluids. Now the WS stuff is call ATF Fuel efficient. It is recommended for many vehicles. Have any of you used the newer fluid?
Regards,
Boyce
