JerryG said:I wouldn't use it in anything. It is just like putting stuff in a radiator to plug the holes. If you have a hydro or a transmission with hydraulic clutches, you don't want anything that can swell seals, plug passages or contaminate clutches or you can have a very expensive repair. Any hydraulic leak needs to be repaired properly because you wallet and health are at risk.
Older tractors with dry clutches and standard transmissions might be able to use it without damage as a temporary measure.
