Oil/Tranny Fluid Leak?

Have a 1996 Ford Explorer, 57K, 4X2, 6cyl SOHC and have noticed
a drip mark on garage floor. Dark color and slippery to the touch. How can I tell if it's coming from the oil or the tranny pan? Thanks.

leaks

Oil leaks can be somewhat tricky to identify because they sometimes "travel" from the original source before they hit the driveway or garage floor.

One "trick" is to put a large piece of paper (preferably white like posterboard) on the floor under the engine/transmission and see what drips on it. Generally speaking, oil is black or light brown, trans fluid is red and coolant is green.

This should help get you in the ballpark as to what's leaking. After that you can try to identify the source yourself or have your mechanic do it for you.

Oil Leak?

Thanks Smogtek. It's likely an oil leak based on your "trick" advice. What does it take to stop this leak? Is this for a DIYer or complicated? Again, thanks.

All depends on where the leak is. Where did it show up on the paper?

Work upwards from the spot on the paper and see if you can trace it back to the source.

Hints: look at valve covers to see if there is any oil/dirt collecting on or around them. Rear of engine could indicate a rear main seal leak that requires removing the transmission to fix. Front could indicate a front main (crankshaft) seal or possible timing cover.

Lots of possibilities. Even if you can't pinpoint it, it will help you explain it to a mechanic if you need to take it in.

If you need more help, just holler.
