1990 4.9L 4x4 5speed tranny oil
Hello, I read in the Haynes manual that my turck uses W80 tranny oil, however when I did the oil change I discovered that it had Mercon, or (red tranny oil) so I put the same instead of W80. I just purchased the truck and I don't know if is the original tranny. Sould i be worry? thanks.
