Mysterious Hydraulic oil leak
I replaced my RB2 passenger side ABC hose due to a leak I identified. After cleaning the oily area and driving for 10 minutes; there is still fluid leaking from somewhere. The hoses are tight and not leaking. The left side where the valve block and pump are located is dry.
I do not think it is oil. Any ideas?

Mysterious oile leak
I have pressure wash it and it keeps coming back. It is not as green as it should be, but is not motor oil. My son who said to check the routing on the transmission electrical connection, which I will do over the next day or two. The trans cooler lines also run through the area where the fluid is collecting. He told me that the synthetic fluid tends to have a more neutral smell like mineral oil if it has never been changed. He may have a point since the car has only 68K miles.
