It doesn;t really matter whether it’s an oil cooler line, and it might be if the car hhas a “tow package”, or an oil cooler line. If it’s really leaking it needs to be fixed ASAP. Nake an appointment with a reputable local owned and operated shop and have them look at it. In the meantime, check your oil and your tranny fluid levels IAW the instructions in the owner’s manual. If the tranny fluid is low, have it towed to the shop. That fluid is thin and can disappear fast. If the oil level is low, bring it up to level and monitor it until you get the car chacked.
