jlyon Posted June 19, 2013 Report Share Posted June 19, 2013 im on the verge of trading in my Edge because of what has happened the last week. i did a tune up on it as it has 113,000 miles on it. immediately a bad coil reared it's ugly head. that was easy to since i have the torque app and bluetooth adapter. now, while driving up a slight hill or just under a load, it bucks some until it down shifts and then smooths out. on Monday, my wife was driving to work and the cluster died and the wrench light came on. also, it felt like the trans was slipping in first really bad. i looked at it and when you put into gear, reverse or drive, was like you were doing a neutral drop, or a bomb exploded in the trans. it has stopped doing that now, and shifts perfectly but the bucking while driving is still there. the cluster works fine too. i scanned the system and there are no codes saved. im thinking it is a speed sensor. i did check the trans fluid and it's not burnt or low. has anyone run into this?

WWWPerfA_ZN0W Posted June 19, 2013 Report Share Posted June 19, 2013 An issue has been noted with the PCM being the culprit behind bad coils. And if it has a bad PCM, it can lead to ALL the problems you have described above. Replacement of the PCM/ECU may be your solution. Quote Link to comment Share on other sites More sharing options...

Replacement of the PCM/ECU may be your solution. with the searching i have done, i did see something about the pcm. i did have a coil go bad and i replaced it. if the pcm was going bad, wouldn't there be a code stored? most of the searching i have done led me to either the speed sensor and/or turbine speed sensor. the speed sensor is on the outside of the trans i can easily do that myself.

WWWPerfA_ZN0W Posted June 20, 2013 Report Share Posted June 20, 2013 Older model vehicles did store a code when PCM was on the fritz, so reasonable to assume the same here. What codes, if any, were you able to pull? Quote Link to comment Share on other sites More sharing options...
jlyon Posted June 20, 2013 Author Report Share Posted June 20, 2013 there are no codes stored. not sure what to do. im looking to trade it in, but my wife loves her edge and we can't afford to buy a new one. Quote Link to comment Share on other sites More sharing options...

jlyon Posted June 28, 2013 Author Report Share Posted June 28, 2013 ok. driving in this morning, the "bucking" was getting really bad and while running down the road it went into "safe" mode for a very short time. once i got onto hwy 121, the speedo stopped, the odo displayed dashes and the wrench light came on. this is the what happened to my wife, and the reason for me driving it for the last 2 weeks. i immediately scanned it, while driving, and it came up with.........
