    Picked up a bottle of Lucas Stop Leak...and the problem was solved!

    My Kubota Tractor had a Transmission Seal that began to leak. Within a few months it began leaking badly. Contacted Kubota Service Department and was told $1,000.00 to split tractor and replace seal. Picked up a bottle of Lucas Stop Leak.......and the problem was solved! Thank You Lucas! - Bob B.
