Synthetic 50 wt. Transmission Oil

Lucas Synthetic 50 wt. Trans Oil is designed especially for heavy duty truck transmissions but can be used in many other applications.

Common gear oils are mostly base stocks with little more than an addition of sulphur and phosphorus as a total anti-wear package. We at Lucas Oil Products consider this inadequate. Most heavy duty truck transmission manufacturers now consider sulphur and phosphorus to be potentially corrosive to copper and brass and consequently recommend against common gear oils for this reason. The other 50 wt. we have tested, synthetic or otherwise, are pure base stock, we consider this also inadequate.

Lucas Synthetic 50 wt. contains an exclusive additive concentrate derived from synthetic oil that ensures lower operating temperatures and better lubrication, especially to upper bearings and gears. This is a long lasting fluid that is far superior to conventional synthetic fluids and contains nothing that could be harmful.

Meets or exceeds API MT-1, Eaton Transmission Div., 164 rev 7, Mack Truck TO-A Plus, International Truck TMS 6816 and other applications requiring non-EP Lubricants.

Bryan McDaniels uses Lucas Transmission Fix for 1989 Honda Accord


My 1989 Honda Accord has 138,000 miles on it. Last Friday on my way home, the 4th gear on the automative transmission went south. All the other gears seemed ok, but it would not lock into 4th(the engine would just rev up and the car would slow down). So off to the auto parts store I went.

A friend of mine that works on trucks and buses said that your product line was the best, so I bought one bottle of the transmission fix. I removed 3 quarts of the old fluid and then fed the Lucas transmission Fix into my Honda. After I emptied the one bottle of transmission fix, I added new ATF to the proper level, cranked up the car and drove off. 4th gear was back! It hesitates slightly switching from 3rd to 4th, but it sure beats the cost of a total transmission overhaul!

Thanks for a great produc
