Default What is correct Transaxle Oil?

What oil belongs in a 3spd transaxle with Hi-Lo range used in Sears garden tractors?(And probably others). What was left doesn't smell like regular 80-90 gear oil. No manufacturers tag on trans. This is the style that the case splits into left/right sections with input shaft on side of trans,with shifter on top.

Bob:

On my Hoyt-Clagwell butt buggy, made from a junked Sears Suburban with two speed axle, I've been using 90W gear lube with a dollop of STP. It's been in there for a few years and there are no ill effects.

I figure that if the 90W is good enough for a car, it'll surely be fine for the Sears tranny.

Take care - Elden

Some use double aught, 00, Zero Zero, grease. Rear engine Snappers use this lube in their gear cases. If there is any yellow metal in theis gear case and you use a transmission/rear end oil DO NOT use a GL-5 oil. GL-4 ,or lower. The GL-5 has a additive for limited slip, posi, rear ends that will attack the yellow metal.

00 transaxle grease should work fine. If it is a cast iron case, SAE 90 hypoid oil (rear end grease), will work as well.

The original manual that came with my 1972 Sears Suburban 12 states very clearly to use 5 quarts of SAE 30 motor oil for service MM or MS (old classification system) in the transmission. Use any good high quality name brand of SAE 30 HD oil. I've been using it for several years and it has never given so much as a wink of trouble. It shifts easily and solidly into any gear I select, whether I am in hi or low range. The transmission is fairly quiet. I only hear very light gear noise on a grade or when pulling hard on something heavy.

Ditto. If its not the cheapo aluminum transaxles that use Bentonite grease then the iron ones were SAE 30 or EP90 oil.
