Komatsu track loader runs great at high engine idle almost all day then no forward or reverse unless idle is very low on engine then it runs all day, Very Slow. Some 10 W Hyd was added to transmission 30 W engine oil after line blew then this problem started, could that be the problem or is electrical or a sensor? Thanks for the help.
