i have some kind of leak from under truck. i crawled under and it is more on the passenger side. possibly tranny cooler lines, but there is kind of a mess around there with some what appears to be an oil leak also. im having a tough time pinpointing it. also when i shine the light up into the area i see a little smoke or haze like im burning the fluid leak off or something. any idea on how i can pinpoint the problem. it is not a large leak, fluid levels are still good, and maybe a 2 or 3 inch spot after 4 or 5 days. any ideas?
