It worked but didnโt last
The sealer stop the leak for a short while but like it says on the bottle it cannot fix a Mechanical fault. It turned out the bolts on the gearbox had gone loose because the rubber gasket had shrunk with age. Had the gasket replace along with a new filter and all ok now. The jeep is 23 years old though.

Blue devil it the real Mc Coy
My 2001 odyssey had a rack-and-pinion leak. A lot of fluid needed to be added about evey tank of gas. M y car is running well, and starts every time. . I bought the blue devel transmission sealer. The next time it needed fluid, I let it go down to about 1/2 of the reservoir.Put almost all of the blue devil in the jar. I didn't expect it to stop the leak. I drove it about 200 miles and noticed the steering returned to like new. Well, I thought it might have stopped the leak. I drove the car more until I had a chance to check the fluid level. The reservoir level was up to normal. The leak has stopped, and my steering is acting like it has a new rack. Blue devel stopped my steering leak.y l,eaks Up date 12/17 Monday I checked the p.s fl;uid jar and its still up to the top. Its not leaking fluid .

Actually works
Transmission started leaking about 2 weeks ago. Wife called me and said there is oil on the garage floor after Ieft. Cleaned it up. The next morning there was oil on the floor again. After investigating I realized it was transmission fluid. Went to Amazon to see if there was anything available to stop the leak. There was several options, seemed like the Blue Devil had the best reviews so I ordered. Took a few days to get it. By the time I got it car was leaking a lot. My car holds 12 quarts of fluid so per recommendation I put 12 oz of Blue Devil in. I then topped of the transmission with 5 quarts of Transmission fluid. So in 2 weeks I had lost about 6 quarts of fluid, so quite the leak. Had my doubts but after driving several hundred miles it looks like the leak has completely stopped. Now if it holds up I will be amazed.
