No i would wait until you get the proper chain case oil that is the correct composition and viscosity

many oils for the chain case ARE 75w's and 80w's.

You can use ATF in there too.

ATF is closer to the consistency of chaincase fluid. Gear oil has greater shear strength which is needed in gear-to-gear contact. A chaincase has a chain and two sprockets. There isn't a requirement for high shear strength in the lubrication. What is necessary is a thinner oil to permeate into the links of the chain for better lubrication.

In the absense of the correct lube, I would run ATF before gear oil. That said, you hardly ever hear of anyone having issues with a chaincase as long as they run something in there!

ATF can be corrosive to metals and certain rubber seals. The transmissions that use it are designed for its properties. Chain cases are more similar to differentials with 75w-90.

But I agree with BC_DAN. It really doesn't matter. If you run vegatable cooking oil, you will get the exact same life as someone with $$$ factory oil. (as long as the ATF doesn't eat your seals and leak out at least, that would be the * in the story.)

Been using ATF in all my sleds for many years and never had a problem with it causing any leaks.

80-90 is way to heavy!
I use 5W30 Syn oil and syn Lucaus oil treatment!
