What type od fluid does it take? And is it a serviceable unit?
Ethan, normally Tuff Torq K46 transaxles do not require servicing for the life of the tractor. However you can check and add oil if desired. If topping off or refilling transmission, Tuff Torq recommends SAE 10w30 grade, non-detergent oil or fully synthetic, SAE 5w50 oil to further increase the life of the unit.
