How does it work?

BlueDevil Transmission Sealer is a unique plasticizer for rubber seals. BlueDevil absorbs into the seal to soften, expand & revitalize the size and flexibility to its original condition.

How long does the repair take?

Start engine and drive vehicle or equipment to let BlueDevil circulate. The repair is sealed while you drive (up to 2 days drive time).

Do I have to change my oil after I apply BlueDevil?

NO. BlueDevil mixes with the oil and can stay in the system.

Can I reapply BlueDevil?

YES. BlueDevil does not contain petroleum distillates, which can destroy seals after temporarily expanding them. It is safe to repeat treatment if other seals leak in the future.

I have had this car forever and although some consider it to be worthless it holds a certain value to me, my transmission started to leak just over a month ago, my local NAPA representative advised me to try BlueDevil out, after driving my car for the weekend the leak was non-existent, thank you!"
