My Tranny has been leaking(2 quarts a week)since I bought the truck a year ago. I have changed the front seal all that stuff and it still leaked. I went to a salvage yard back in Dec. The guy at the yard told me to put a cup of brake fulid in the tranny. I blew him off. My tranny started slipping bad about a week later so I tried it and it worked. A few day later I put some slick 50 in. when I did this, it was about the first of the year. I HAVE NOT LOST ANY FLUID YET THAT I KNOW OF AND SHE DRIVES LIKE A DREAM!

Does any one know how this worked?

 

Most powersteering fluids have silicone in them for the seals, most transmission fluids don't. The silicon soaks into the seals and makes them swell up, makes old dried up seals swell back to their original size.

 

I put Brake Fluid in it.

 

this is a old use cars saleman trick (patch job) yes brake fluid makes seals swell up... as long as it working good luck but when it starts leaking again you'll probably have to replace seals agian...

 

Brake fluid...power steering fluid, they are about the same. They are both hydraulic fluid with silicone.
