Jamie Barnhard uses Lucas Transmission Fix in 83 Mercedes & Marine Transmissions

I have a 1983 Mercedes 300TD that shifted hard and had a front main seal leak. I was on a trip to Florida from Maryland and picked up a bottle at a truck stop in South Carolina. Not only did it shift better the main seal stopped leaking. Amazing Stuff. As a Marine Engine Mechanic, I started to using Transmission Fix in a lot of boat transmissions. Borg-Warner Velvet Drive, Borg Warner V-drive, Walters V-drive, Tonan and Twin-Disc. Transmission Fix works has worked wonders in them. Thanks for a great product.
