REDLINE is the best I have ever used. Makes the FOD tranie shift like hot butter.
Brad Penn or RedLine. Or Gibbs oil if you have a lot of $$$. -Dave-
Is that the BP classic GL4? Does nobody run synthetics?
i use mercon atf in both rear end and transmission.. less drag all around
Mark 41 forgot to tell you.... ( and you non diesel people may NOT believe me) but after he drains the rear end and tranny, he puts/re-uses that fluid in the fuel tank of the tow vehicle and burns it on the way to the track !!!
why yes i do Buddy!
ATF with a splash of lucas oil treatment and cam break in additive ( zinc additive....7 bucks at advance) oem is too thick causes drag
