I have confirmed that this is transmission fluid. Appears to be the wrong transmission fluid too. The Manual calls for NH 134. What I believe is being used is "Super S 303 Tractor Hydraulic Fluid" The label on the back of the 2.5 gallon jug states that its not suitable for use in equipment...
I'm new to this forum and see there is a wealth of information available with tons of helpful people. I am posting here to hopefully get some help in providing me with some information to repair my New Holland TC18 tractor.
I seem to be leaking fluid near the Hydrostatic Transmission Assembly...
