Oil for saginaw 3 speed

[bobdoo]

Was wondering what type/weight and proper amount to put in my gear box.

[UltimateRaceCars]

75w90 gear oil, really any gear oil will work. Or if you want something lighter Joe Gibbs MTF.

dexron 6 auto trans fluid. no need for thick stuff in a manual trans.

I second stockcar5 that is all we run. Do not try it in the rearend to much heat generated there.

Thanks for the info guys. What are your thoughts on the proper amount? Up to the fill hole ?

[dirtplay18]

1/2" below the fill hole

Was told years ago only reason for heavy lubricants in a manual tranny was for noise reduction. I see no need for that in a race car.
