I was looking at a transmission service kit for our 2010 Range Rover Sport. Lucky8 has a kit with the new two-piece pan and filter, plug sleeve, screws, gasket and 7 quarts of transmission fluid. They also include free shipping. Lucky8 said the the fluid is Rock Oil 6 HP. I am not familiar with Rock Oil (individual liters are $30 each). Atlantic British has a similar kit but they offer the the AF Lifeguard Transmission Fluid. The Lucky8 kit delivered is $246. The Atlantic British kit is $309, with shipping added is $332. FCP Euro carries the ZF Lifeguard ATF but they don't carry the two-piece pan and filter set.

Has anyone used the Lucky8 kit with the Rock Oil ATF? Is it worth saving $80? Recommendations. Thanks Phil
