VP Racing Transmission Fluid Additive – VP ATF Pro

It worked

I have a supercharged car with a heavy duty transmission. I had noticed the shifting becoming a little rough and a loss of power. Now I am not a subscriber to repair or mechanic in a bottle. But this additive sounded like it would help rejuvenate my fluid a bit. I do use a friction additive in my crankcase so with the transmission being worked as hard as I make it do, I figured a little extra protection couldn't hurt. Well this stuff has impressed me. My transmission has smoothed out, my engine temperature is noticeably cooler on the gauge and that's with this 90 degree plus temperature this summer. I beat on my car and it has just been so much more responsive since I added this stuff. all I can say is it definitely worked in my car. I am not claiming it will fix you transmission, but if you have had the fluid in there for a while and it is still fairly clean, go ahead and add a bottle. I was glad I did.
