troy bilt super pony question

[bandit2010]

hey guys i have a 2007 troy bilt super pony, that I am going through the differential on it due to wear and tear. my question is. I know the transaxle takes darina grease made by shell. i have it apart and cleaned up is there any alternative that i can use that will work just as good or better. the reason I ask is 1 I cant find it, 2 If I can I imagine it is gonna be expensive.

the model number is 13bx60tg7666605 from what I can see the darina grease is being phased out, and from what I can see 00 grease would be the correct stuff.
