My Honda Element 5 speed manual had a pretty bad leak. With every oil change (approx. 4,000 miles) almost half of the fluid in the transmission was gone. I filled in BlueDevil transmission sealant and eventually the seepage stopped. However, this took some time. After adding BlueDevil, I cleaned my gearbox from the outside. I could clearly see drops of liquid on the outer bottom of my gearbox. I would wipe again and wait. Gradually, the appearance of drops slowed down, and then stopped completely. I've driven 40,000 miles since using the BlueDevil and it still doesn't leak. Impact product. Thank you BlueDevil!
