Hello, I'm looking to replace my rear main seal, which appears to be causing an oil leak down below the oil pan. Trying to figure out exactly where it's located at which would give me an idea of how to replace it. Thanks for any assistance.

You may not have a rear seal that is bad, I have seen the crankcase ventilation system fail or clog which forces oil out of the rear main seal. The transmission will need to be removed to replace the rear main seal, here is how the seal is replaced once the removal is completed. Check out the images (below). Please let us know what happens.
