Extreme Duty Marine ATF

Lucas Extreme Duty Marine ATF is a blend of specific synthetic base oils and a special Lucas additive package designed to create a high friction fluid that allows shifting clutches in the transmission to lock up and engage quickly. A faster shift means less clutch slippage, therefore, less heat and wear in the transmission.

Robert Howard uses Lucas Semi-Synthetic Automatic Transmission Fluid in 2000 Ford F150 5.4

I have a 2000 Ford F150. I recently changed my transmission fluid and installed a high preformance shift kit. I replaced the fluid with the Lucas Semi Synthetic ATF and Lucas Tranmission fix because I know thats what Lucas bases thier products around... Performance! Man what difference in shifting. Its shifts fast and very crisp. I am very pleased with this product and do recomend it to others. I have used Lucas oil products for years, and i trust thier products. Thanks for making such great products!
