Hi I have 2010 Ranger 4.0L XLT automatic. When I was doing a radiator flush I noticed that my transmission fluid cooling lines were very rusted/corroded which I understand are known problems. So I went about replacing them before they broke on the road. I found www.linestogo.com. They sell a complete set of stainless steel lines which were not much more costly than the rust prone OEM parts. They're a real high quality part, great customer service and overnight delivery included in the price. The parts are made in Canada. The parts fit perfectly. I highly recommend them if you're in the market for replacement transmission lines.
