If you find oil leaking from the bottom of a car could it be from the head gasket or the transmission?

Answer 1

The leaks could start from anywhere due to wind blowing through the engine compartment while driving. Try to trace the source and identify whether it is oil (gold/brown color), or tranny fluid (usually dark red).

head gasket? that's the top end..oil pan is probably it..either the gasket is pinched, the bolt isn't tight..or one of your seals is bad

If its oil its either gold or black and like above probably the oil pan. Transmission Fluid is generally red.

A very simplistic way to determine what the fluid is that is leaking, is to dab a small amount on the end of your finger and taste it. All four of the most common fluids (oil, tranny fluid, brake fluid, and antifreeze) have a very distinct taste and are completely different from each other.

that doesn't induce carcinogens:

Even easier way to identify fluid without ingesting it is to simply park over a piece of paper or cardboard. You can also use a white paper towel and dab it off the ground to get a decent idea what the fluid might be.

Head gaskets usually don't leak alot of oil, normally they start dumping antifreeze into the cylinders when failing. Valve covers (the part just above the head is the likely culprit there). Most higher mileage cars with oil leaks are typically the rear main seal on the crank that is failing. It is sometimes costly and others not so bad depending on the vehicles.

ANSWER

LOOK AT THE COLOR OF THE OIL IF IT IS REDISH COLOR ITS TRANSMITION IF BLACK ITS FROM YOUR HEAD GASGET AND THE BEST THING TO USE WOULD BE ORGANIC SEALER UNTIL YOU HAVE ENOUGH TO COMPLETELY FIX THE PROPLEM
