rkierstead8 Posted February 9, 2018 Report Share Posted February 9, 2018 (edited) First of all, I want to say thank you for the wealth of information that is on this forum. I've been reading through some topics and I plan to continue doing so until I find a resolution. The reason for this post is to get some advice specific to my problem, so here goes. We've had our edge for about a year now and It has been leaking from the PTU for some time. (not sure how long). It is bad enough that we have a small puddle in the spot where we park in our garage. When I saw the spot I did some preliminary research and knew about some of the PTU issues with these cars, but now I think I'm at a cross roads where I HAVE to do something. We've had issues with a loud clunking noise when going into reverse and at time while accelerating onto the interstate. Yesterday her car wouldn't crank because the battery terminal was loose. I'm sure that is purely coincidental, but after I came and tightened it up for her and got her headed home, the transmission started to slip. This is especially bad around 20-25MPH and is fairly consistent. I've read about some sensor issues that may cause issues, but I'm lost on where to start. I know financially I can't spend thousands on a fix for this thing especially if I can't pin point the problem. That's where I'm hoping this community will help point me in the right direction. If the PTU is bad could it be causing the trans to slip? Are there known internal issues with the transmission that might cause something like this? Please help!

akirby Posted February 9, 2018 Report Share Posted February 9, 2018 Do a search to TSS OSS sensors. 1 Quote Link to comment Share on other sites More sharing options...
rkierstead8 Posted February 9, 2018 Author Report Share Posted February 9, 2018 That is one of the things I was looking into akirby, so thanks for the suggestion. I don't have a "limp" mode going on... is it possible to have the slipping as a first sign of the problem? How could I recognize a failing PTU? since I know it's be leaking I'm scared I've messed it up. Quote Link to comment Share on other sites More sharing options...
rkierstead8 Posted February 9, 2018 Author Report Share Posted February 9, 2018 (edited) Any idea on the best place to find the sensors? I'd like to find them in a store so I can try to replace them this weekend, but that isn't looking likely. Edit: Still can't find a store, but can anyone clarify if these are the correct part numbers before I order them. It's hard to believe that they half the cost compared to the others that I have found. https://smile.amazon.com/gp/product/B072PPY6DH/ref=ox_sc_act_title_1?smid=A3B850ZGIPDG3A&psc=1 https://smile.amazon.com/gp/product/B071FF1L6H/ref=ox_sc_act_title_2?smid=A3B850ZGIPDG3A&psc=1 Edited February 9, 2018 by rkierstead8 Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted February 9, 2018 Report Share Posted February 9, 2018 Check at your local NAPA dealer. Most Ford dealers look to local NAPA dealer as parts supply for parts they don't stock. Should run about $30-$40 each. Quote Link to comment Share on other sites More sharing options...
rkierstead8 Posted February 9, 2018 Author Report Share Posted February 9, 2018 I called and they don't have one in stock, so I'm out of luck this weekend. I'm going to order the amazon ones and just deal with the slipping for a few days. Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted February 10, 2018 Report Share Posted February 10, 2018 Would also do the Transmission Range Sensor at the same time, to fix the clunk into reverse. If you can take apart the valve body for inspection so much the better. Be sure to know where every bolt goes because a couple of them are different sized than the others. Same with checkballs if you have the VB apart. Get the filter/gasket assembly for the Solenoid Body Assembly. It's like $11 so well worth it to keep those shift solenoids clean. SBA might need replacement if shifting does not clear up with TSS/OSS. And oh, make sure the trans is in Neutral and battery is disconnected before beginning work. You will be glad to avoid doing the work twice. Quote Link to comment Share on other sites More sharing options...

WWWPerfA_ZN0W Posted February 10, 2018 Report Share Posted February 10, 2018 Also, make sure the Edge is ready for inspection status. The battery situation may have set off a PCM relearn. You can check the I/R status without any extra equipment, as specified in the owner's manual. To determine if thevehicle is ready for I/M testing, turn the ignition key to the ON positionfor 15 seconds without cranking the engine. If the Service enginesoon indicator blinks eight times, it means that the vehicle is notready for I/M testing; if the Service engine soon indicator stays onsolid, it means that the vehicle is ready for I/M testing.The OBD-II system is designed to check the emission control Quote Link to comment Share on other sites More sharing options...
