I will be towing my 2013 AWD Ford Edge behind a Class A. I have it set up with the Blue Ox towing system. My question is does the PTU continue to spin while being towed. Given the nature of the PTU troubles I would change the fluid/add the drain plug if it does spin. thxs in advance for any help.

I bought my 2013 to tow behind a Class A , I have installed the blue ox towing system and am now in the market for my Class A. Does the PTU gearing spin/turn while the Edge is being pulled? As that would put even more stress on the gear oil. I didnt have any leaks just the PTU gear oil puking out the vent after hard driving/towing. Cost me $85.00 for ford to tell me the PTU was overfilled. That's when I started to research the PTU filled for life troubles.

I have 44,000 miles on her. I have since sucked out and filled the PTU twice. I used valvoline syn 75w-140. I am going to change it one more time but switch to Mobil 1 syn. On the second change the oil was much more viscous and the terrible odor not near as potent. I replied to another post on the PTU fluid change and wrote how I did it. Second time I did it in 45 minutes. I looked into having the oil checked from the first removal but it was costly.. $140 per sample.

I drove my edge up onto 4 ramps, with the rear set of ramps 1" taller than the front set. This allowed the oil in the PTU to settle toward the front of the car. When removing the plug a small amount of oil will seep out of the hole, use rags to sop it up. I then used a magnetic battery operated light and stuck it onto exhaust and pointed it at 3/8" square female plug. I used an ALEKO hand operated pump. Bought from Amazon for $12.00. I also purchased clear tubing, 1/4" od , 5/16" od and 3/8" od. I bought 2' of all 3 sizes from a local Hardware store. The pump comes with tubing and I used the 1/4" and attached it to the pump tubing. Warm up larger tube in hot water and the smaller tube will slip inside creating a tight seal. The 1/4" od tube will reach to the bottom of the PTU cavity. I was able to easily push it in 5 or 6 inches. I marked the ALEKO container to show a capacity of 18 ounces. That way I knew if I was getting most of fluid out. On my first attempt I was able to suck out almost 18 ounces. I also had driven car for 20 minutes prior to driving up on ramps. Oil was quite disgusting, very black and terrible smelling. I then measured out 18 ounces of Mobil 1 syn. 75w-140 and poured it into a empty and clean Golden Rod oil can. I used a piece of the tubing about 12" long and attached it to the end of the flexible snout. I then hand pumped all 18 ounces into PTU. I used a 1/2" street ell and loosely threaded in into PTU. This allows you to get all 18 ounces in. The PTU drain plug has a magnet on the bottom, let it stick to the exhaust pipe while you unscrew street ell, oil will come out but quickly insert PTU plug and tighten. I used this process 3 times, bought 2 quarts of fluid, the tubing, the ALEKO vaccum pump and the Golden rod pump style oil can for around $60.00. I will change it on a yearly basis from here on out. The car shifts better and its quieter. My PTU plug did not have any metal on it after any of the changes which were one week apart. It really is an easy service to perform too bad FORD wont do it as part of its service intervals.

Good morning all, first time forum member post. I am looking for the TSB that refers to the PTU fluid change. I have looked but cannot seem to find it. I have the NHSTA 10057723 and ASI 44649 numbers. The edge started puking heavy black fluid from vent on top of PTU. Ford service said PTU overfilled. I would be great full for any help. thxs Mschluns
