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.

Ordered this to try and "clean up and free up stuck/dirty solenoids" in a BMW transmission. Added this to the transmission and drove it around the neighborhood to get the fluid flowing. THIS STUFF WORKS!!! The transmission has 166k miles and fluid has never been changed. The transmission would not downshift when going up hills and would give a code for the solenoid. I bought this to clean up the transmission and free any stuck parts before doing a fluid change and this stuff did the job and then some. Transmission is shifting great and acts like a new transmission. Great value for a product that works.

I used the product with the aim of cleaning up my steering rack hydraulics. It made a slight improvement to the racks workability. It was my cheap option before choosing to replace the rack.

Los Honda Accord 6ta generación son famosos por su transmisión que se deteriora muy rápido. La mía ya pateaba fuerte y no metía segunda. Le hice el cambio de aceite junto con este aditivo (siguiendo las instrucciones) y el carro funcionó perfectamente 5 minutos después de dejarlo trabajando. Volvieron a. Entrar los cambios como se supone debe trabajar la transmisión!

ممتاز. اصلح لي المشكله. فورد كروان فكتوريا. كلهم قالوا يحتاج توضيب بس المنتج بطل

Used on two 13 year old vehicles. Power steering noise reduced and steering became free. Am changing the power steering oil after 200 kms of running. Will add a fresh batch of this oil to keep the system in shape.
