Review on Enhance Performance with Prolong Super Lubricants PSL15000 Transmission Treatment - 8 oz. by Jeff Bridgewater

I just bought a car with a rebuilt gearbox and was just thinking what product would help protect my new gearbox? Yes, this is the product I have used on all my vehicles. . "Extension of transmission processing". Not only does it protect against all the moving parts in your transmission, but it also reduces friction that causes heat, and your transmission doesn't like heat. This product protects against "friction and heat". The transmission runs smoother and makes shifting easier. Compatible with all major transmission fluids and oils, this product can be used in new and high mileage vehicles. And what I like is "made in the USA". and while you're at it, try "Extend Engine Heal". I just changed my oil and added a bottle of this so I can "protect" both "engine and transmission".
