Does it work on automatic transmission i have ford galaxy.

It helps but if the transmission is slipping it will need repaired. To answer your question it works for all auto transmissions.

Can just fix my car it is a Rover City and I have a power steering leak

I didn’t find this product to be effective at all. In my view a waste of money.

Will it stop leaks on a L200 automatic gear box

I used it on my manual gearbox leak, I had tried other so called leak stoppers ( Lucas - Wynns) that didn't do it. Thought I'd try Bluedevil and it cured the leak within a couple of days, fantastic stuff. Only negative is the price you pay for a bottle then only have to use a couple of fl. oz's of it. But hey, it's a hell of a lot cheaper than having to replace gearbox seals, go for it. PS - if you live near Doncaster you can have some of what I've got left.

It worked but didn’t 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.

KEEP AWAY!!!

So I had a leak in my torque converter. I had been recommended this so I put half the bottle in my gearbox and little over a week later the gearbox failed resulting in me having to buy a refurbished box at £1000. Do not put any additives into your gearbox.

Made my leak much worse!

I had a slow leak on my Volvo V60 Automatic gearbox, about 1 litre every 4 or 5 weeks. I added Blue Devil and it made it much worse, effectively dumping all oil in a day or so. Beware! My car is currently in a Car Garage getting fixed...

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 .

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.
