Looking for information about the wires that go around the transmission cover and the over floor tube that hours on the drain plug on inside

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your SLK320. If fluid is present on these wires, it could indicate a failing transmission electrical connector or a damaged seal on the conductor plate. Mercedes-Benz transmission systems are sensitive, and replacing the wires or seals when fluid contamination occurs is advisable to prevent electrical shorts or erratic shifting. The exact part numbers depend on the VIN, so contacting a dealership is the best way to confirm them. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
