Reply To: Trans. and axle oil viscosity

As previously indicated, I use a modern 140 in my rear axles.

The GL-1 recommendation applies ONLY to use in the Borg-Warner OVERDRIVE transmissions…and nothing else.

The basis for this, as previously indicated, includes actual experience with sticking overdrive causing engagemant and disengagement issues. A non-EP lube works based on my personal experience and an EP doesn’t.

I do wonder about “scientsists”” who work answering help lines being given great credence. Trust in experience from PAS members is best.”
