Overall this is a very good product but still needs some research. Not me. I installed a brand new power steering pump on a 2007 Nissan Altima. I pulled as much of the original fluid out of the system as possible. 100% Triaxx put into the system, super vented and the pump ran very smoothly. At idle, however, control was difficult. After some research, it turned out that Triaxx has a lower viscosity than the manufacturer calls for, which is basically Dextron III. I sucked as much Triaxx out of the system as possible, overfilled the Dextron III tank wheels up, rode back and forth the whole route 20 times. Have vacuumed the tank, performed this process 3 times. At least the power steering is now working properly and there is still some Triaxx in the system which adds some great lubes and additives.
