AX-4 4spd Manual Fluid ?

Recommended Posts

I'm not worried truck ran most of December with 20-50 super tech oil that was 2 years old n had 50 miles on it, it's got 10-40 AMSOIL now . . .


So i highly doubt that there will be a noticeable difference between 75-90 and 75-140, both are 75w so they should be the same cold, it not it'll get over it . . .

I was just saying 75w is 75w ?


i already have or rather had a 5gal pale of the 75-140 is why i was asking. . .





Will it work..yes..


But it will take longer to warm up enough to shift correctly than a 75w-90 would.
