I did the siphon gun exchange of my PS fluid with Valvoline SynPower last spring. Much improvement over the 100k juice.
However, when sub zero temps arrived this fall, the dreaded howl returned.
I had great results from Lubegard trany additives so decided to try the PS additive.
I siphoned the reservoir dry, added the Lubegard, and topped off with Valvoline in warmer temps (around 32°F). I noticed a slight whine in the pump disappeared.
This morning it was -10°F and the pump didn't howl on start-up. I tugged on the steering wheel and no howl. I stepped on the brakes and no howl. I stepped on the brakes and tugged the wheel and no howl.
This afternoon, the temps were around +5°F. Again no howl with the same test.
I am really impressed with this product.
