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...
