I have a 2007 LR3 SE and the other day it turned on fine but when I placed it in reverse it wouldn't move and a "transmission fault limited gears available" appeared on the display as well as an "F". I read all around different forums about checking the battery and stuff like that but I noticed a puddle of oil on the ground below the driver side. It doesn't smell or look like engine oil. It's a light brown color fluid. I checked the engine oil, power steering and brake fluid levels and they're all good. The only one that is a little low but still above the min level is the brake fluid. I checked around the brake booster and brake reservoir for leaks and it was clean, no signs of leakage. Can anyone point me in the right direction? Thanks!
