Like some of you I started to use ATF in my tranny.I don't know why but I did it.Can you tell me what is the deal with ATF cauz i did not saw any changes ...Maybe it is better for the gears?Also should I use type F or not?ATF seem to be more thinner than 10w30 or gearbox oil.Does it matters?Thank you and be happy to ride your green tractor!Phil
