I have a 2w drive and I did a oil change recently. I think I did it wrong though. I removed the oil filter and placed it with a new one. The only thing is that I drained a fluid that might of not been the oil. I drained a liquid that's in the panel in the middle of the vehicle. It looked like the oil panel so I loosen out a bolt and liquid came out. The next day my car would shake when I would keep the car in a stop or as a start to accelerate. I looked on YouTube and everyone is un screwing a different bolt that I took off. So can anyone help me out and if you have an idea of what liquid I took off that would help. Thank you
