Any fluid leak should be inspected by your shop to verify the source. Trying to identify fluid on your driveway or parking lot can be a bit tricky. Coolant while water based, can have an oily feel on your fingers and may lead you to think it’s engine oil. Engine oil and transmission fluid are similar, but transmission fluid if not too spent, will have a red look unless it’s a CVT transmission. Engine oil could be darker looking, or clear if you just had the oil changed recently. Brake fluid is usually clear, but oily feeling much like engine oil. Checking the under hood fluid levels many times can lead you in the right direction.
