smze490 Posted June 18, 2014 Report Share Posted June 18, 2014 I have a 2008 Ford Edge, about 83,500 miles. My transmission started to stutter, jerk before shifting. This happens about 40-45 mph and around 60 mph. I took it to the dealer where I bought it. Now 3 vists later and spending $1700 for a new PTO unit and seals. I still have my original problem. It is most noticable when going up an incline. The tranny stutters, jerks, then RPMs climb and speed picks up a little. This is starting to happen more. The dealer does not know what is wrong with my car. Does anyone have any ideas? Quote Link to comment Share on other sites More sharing options...
macbwt Posted July 12, 2014 Report Share Posted July 12, 2014 Rear output sensor on the tranny. Really surprised the dealer did not pick up on it as it is a common failure as you build up the miles. It will do that for awhile then eventually fail. once it fails all your dash indicators will blank out and all the warning lights will come on. Then the RPM will increase and the spedometer will drop to maybe to zero depending. If you are on the intersate keep driving, because once you slow down or stop it will take a long time to get it moving again. It sort of feels like it is reving up but moving very slowly and as you go it will build up speed and get going again. 800 dollar repair. 1 Quote Link to comment Share on other sites More sharing options...
SlickBlueEdge Posted October 19, 2014 Report Share Posted October 19, 2014 Is this sensor something that a savvy mechanic can repair? I'm just starting to get this issue, and it "clunks" when shifting into reverse. Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted October 19, 2014 Report Share Posted October 19, 2014 (edited) I would think so, as long as you have access to a proper lift. Lookup the removal/installation process in the free online Chilton's via the INFOTRAC url at http://hmcpl.org/databases/auto-repair-reference-center That link is not working right now, may have been shut down. Recommended you change both TSS & OSS at the same time, you are in the area anyway. 2007 Ford Edge_TSS & OSS Sensor Replacement Procedure.PDF Edited October 19, 2014 by WWWPerfA_ZN0W Quote Link to comment Share on other sites More sharing options...
wannabang Posted October 20, 2014 Report Share Posted October 20, 2014 I've been having this issue since I bought the car a couple years ago, but it occurs usually on take-off or right after coasting awhile. Figured it was just cuz the stall only kicks in at a certain rpm level. Car hasn't failed, yet. Quote Link to comment Share on other sites More sharing options...
Camshaft Posted October 22, 2014 Report Share Posted October 22, 2014 Any fault codes? 1 Quote Link to comment Share on other sites More sharing options...
SlickBlueEdge Posted October 22, 2014 Report Share Posted October 22, 2014 Any fault codes? I have no fault codes, but I'd rather not wait until the failure. Quote Link to comment Share on other sites More sharing options...
Dr Fildo Posted December 1, 2014 Report Share Posted December 1, 2014 I recently had the same problem. 2008 AWD - 96,000 kiles. Jerking between 40 & 60 mph, usually following coasting. Worse on slight inclines with soft gas pedal pressure. No fault codes. I took the car to Ford. They told me the #5 coil and plug needed replacement and wanted to charge a little over $350.00 for the job. I was skeptical that this could cause the problem. I bought the coil and the plug from Ford (I wasn't giving them $350 for this easy a job.) (plug was pre-gapped, which was nice) for a little over $150.00 and installed it myself. It was a breeze because the #5 coil and plug are right in the front. It's the middle of the 3 plugs/coils in the front bank. Took all of 10 minutes. Problem solved!! Do this. You will not regret it and probably will be as amazed as I was that this could cause this kind of problem. Quote Link to comment Share on other sites More sharing options...
edgingit Posted December 11, 2014 Report Share Posted December 11, 2014 I have an 08 Edge Limited AWD. This past year the transmission started slipping in 1st gear and clunking when I shifted into reverse, so I took it to the dealer and they said the transmission had a leak. The leak was repaired and my transmission continued to slip in 1st gear and clunk in reverse after I picked up my car. I waited about three months before taking it back to the dealer because it was a sporadic issue and I could never tell when it would happen. I was hoping to come up with a common relationship to the problem but it was too random and I could never get it to repeat when needed. I spent about $1,500. on the repair. Recently I took my car back to the dealer and explained that the problem was not fixed. They were unable to repeat the issue but replaced two sensors at a cost of $500. The service tech called me and said as the technician was parking my car he finally heard the clunking in reverse. They told me it was in internal transmission problem and they needed to take the transmission apart to find out what part is bad. They said my warranty will cover most of the cost and it will be $1600. I agreed to the charges and work was started. A few days later, the service guy called me to say my warranty was only going to cover $600. and that I needed a new transmission which would cost $6,000. Keep in mind that my car has 70K miles on it and has never had any issues. I have it serviced on a regular basis and they recently repaired the transmission. Long story short, I was fuming and told them I am not spending 6g's after they told me it would cost $1600. I did not completely understand why it needed a new transmission but they had my car for three weeks at this point and had accomplished nothing. On top of that, my extended warranty company adjuster said when he looked at the transmission, it did not look damaged at all. I decided to have another mechanic pick up my car and install a used transmission from a 2010 Edge. I spent $2300. with the new mechanic. I picked up my car and one week later, I am experiencing the same issues, slipping in 1st gear and clunking. Needless to say, I think the dealer SCREWED me when they took my transmission apart. After reading a lot of these posts, I think the issues could be related to a SOFTWARE update to the car's computer. I'm taking my car in to another FORD dealer for the update and if it works, I plan to trade my car in. I'm NEVER buying FORD again. Worst experience ever with my dealer!

WWWPerfA_ZN0W Posted December 11, 2014 Report Share Posted December 11, 2014 Sorry to hear about the bad experience with the dealership. I have run into this issue many a time, where the tech is unable to replicate the problem initially, and for many "wasted" return trips happen before the problem is solved. Some of it can be attributed to the electronics-heavy nature of the vehicle, some of it to a dealership's reliance on a code popping up to prove a problem exists. You might even hear, "Oh that's to be expected from this type of vehicle, it's an SUV"! General thoughts for anyone in this situation: First off, take a dealership (or anyone else's) diagnosis with a healthy dose of skepticism. Second, do your own research, you might get lucky with a TSB or two that kinda fits the issues you are experiencing (even if not exactly the model years listed). Ask around, there might be others who are/were in the same boat. Third, feel free to document & escalate the issue to Ford Customer Service directly (listed in owner manual). And lastly, try changing dealerships, maybe even try a Lincoln dealership instead. Better luck with Ford extended warranty than non-Ford, usually too! Good luck with the software update. 1 Quote Link to comment Share on other sites More sharing options...

You will not regret it and probably will be as amazed as I was that this could cause this kind of problem. Had this happen on my 08 Taurus X 248,000 miles, for a couple of days it did it twice each day. Third day it threw a check engine light and started missing when I was accelerating on the highway. Checked the code when I got home and it said cylinder 5 miss. Pulled the coil and it was destroyed with a bunch of crap down by the spark plug. Cleaned it up the debris, replaced the plug and put in a Duralast coil, total cost $61. Now no more issues, but it is the first day driving it, so time will tell. I will probably just replace all the coils now, especially with the mileage. Had put in new plugs 10 months ago and the coils all looked good at the time.
