I'm adding an external cooler and will probably change the fluid while I'm at it. Is there any downside to using that tractor fluid on a stock tranny with an Art Carr kit? If not what is that fluid really called?
Absolutly!
We use either Torque Fluid (Chevron) Some like the Mobil424.
or We use mostly Citgo Power fluid.
Same stuff. With yours just add it at the service. When filling from new we mix 70 tractor to 30 ATF for color so if you have a leak you do not think it is motor. Tractor is amber in color like motor oil. Most companys will only sell it in 5 gallon mininums. If not that much is needed , we can ship some to ya... If you have trouble locating, let me know EXACTLY where you are and I will find the nearest dealer to you.
Good Luck....BT
