Gear vs Tranny Oil

[BriantheBrain]

Does anyone know the difference between Delo 80w90 gear oil ESI and Delo Transmission fluid ESI?

The Transmission fluid is designed specifically for transmission use and only comes in SAE 90 gear weight (14.5 cSt) or 40 weight engine oil, whereas the Gear Lube is a general all purpose gear lube and comes in 80W90 and 85W140 weights.

Specs say the 80W90 fluids have the same viscosity at 100C.

Do you have an apllication for this fluid?

Its a 1986 Jeep CJ7. I have to rebuild the transmission (T-176) and am looking for an oil for it. I saw that the Delo line uses a boron base instead of the sulfur base. But I called the local distributor and they have both for the same price but the smallest container is 5 gallon. So I figured that I would get something to use in the transmission, transfer case (D300) and axles.

I use DELO ESI in both 85w-140 and 80w-90 and both the gear oils are available in quarts. Not sure about the gear oil Great stuff!!

No reason to stay married to Delo.
Also consider a premium manual trans lube from Redline or Amsoil that meets your viscosity requirement.
Regular gear oil [differential lube] is not the best for manual transmissions.
