A state-of-the-art conditioner and stop leak in one. You get the superior performance of Enviro-Safe Automatic Transmission Conditioner, which allows smoother shifting, removes varnish build-up, and adds lubrication, with the bonus of a stop leak for seals. The stop leak conditions seals and then swells them, restoring the to "Near New" condition. This prevents transmission fluid from leaking, thus fixing most transmission leaks.
