Trans Tune Transmission & Hydraulic Systme Cleaner,Helps Systems move smoother, Cleans and Lubricates and controls moisture 473ml

Really did the business on my 33 year old PS system. Steering became heavy & notchy on direction change (possible sticky/partially blocked valve body?) so flushed the system out, added new fluid then poured in this additive. Smooth, quiet operation within 10 mins, with more steering assistance in the 12-years I've had the car. Worked a treat for me!

Instantly quietened down my power steering pump. Before putting this in, it was extremely loud

Useful fluid for car maintenance. Have used it once but probably need to use it again to get the desired benefit. Hence, not a 5 star at the moment. Will update if this product delivers results as claimed.

Very good product did a good job of cleaning my power steering system.

Flushed my power steering with this. syphoned out the chamber a couple of times and refilled over a period of a week before replacing with new fluid. now the steering is not binding and like new. the old fluid was sludge-like.

This is aa good product for use in hydraulic fluids and gave a noticable improvement when added to the steering fluid in my car.

Used this to referb a power steering pump that kept overflowing. Simply followed instructions and then pulled all fluid out with a syringe. Refilled with fresh power steering fluid and all is good now. A refreshing change to find a product that really did do what it said on the tin.

I had major issues with my automatic. I read several forums and bought this. You add it then drive around then drain it. It has made my auto box run really smooth. Very impressive and saved my thousands on. A reconciliation auto box.
