MTD Lawn tractor transaxle lube

A YOUTUBER packed his with grease. I saw where another person claims that grease is why a rebuilt trans axle fails. When I looked for the MTD lube, Benalene grease is listed. That stuff is expensive, in small tubes, and which is the right stuff and how much I would need would be a guess. Evidently another option is the "00" grease. Again different manufacturers and part numbers. Does it really matter, as long as I put a "00" in it. I might try to sell this machine and I don't want it to be a time bomb for some one else.
Thank you

A lot of the transaxles were made by Peerless and had ID tags so you may be able to get service info based on that. My experience in selling parts for Peerless equipped lawn tractors that a "00" grease was typically recommended. Usually, the transmission cases of those were made from aluminum or some light alloy. Often a corn head grease will meet that spec so you may be able to go to your local farm equipment dealer for it. For comparison an older Cub Cadet with cast steel manual transmission typically required an 80-90 gear oil.
 
I would use the 00 grease. JD cornhead grease, NH cornhead grease or Snapper 00 grease. All are good and won't push away and clump like the original stuff did.
 
I have an older Ranch King which is an MTD built unit and book on it says 30 weight motor oil. I have changed once and used 30 weight motor oil and lucas oil stabilizer.The tractor is a 1987.

We are talking a "gear" transmission, not a hydrostat...

Some of the gear transmissions didn't even have seals, so any type liquid oil is out of the question.

The 00 grease would be my choice, even if it did have seals.

If you have it apart, might add some grease fittings up top, anywhere grease is not likely to go on it's own and water is likely to come in, like around the shifter shaft.
 
This is a single speed trans axle that has a 7 speed shift and a forward and reverse option. There are not any seals that I can see. The bushings will leak what ever is in it, out the end of the shaft that selects the Forward or reverse option. What is left in it is a dark gray goop.

I know one thing for sure. I bought an old tiller for ten bucks and 90# oil ran through the gearbox like water. I pumped it full of regular old gun grease and w/I 5 minutes it was smoking hot, squalling, and the grease ran out of it thinner than the oil had been. Needless to say, it was cooked. gm
