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...
