Back in 2015, my 2008 Ford Edge had accelerating issues with diagnostic codes:P0715, P0717, P0720. My OSS & TSS speed sensors were replaced, codes cleared, etc.

 

Now in 2017 (just shy of 2 years later) the car is showing delays when shifting into/from R and D. Additionally, the car seems to putter when I drive between 45-60mph.

 

The car only has 85,000miles at 9 years old. My last oil change said the transmission fluid seemed a bit low (since the previous oil change) but nothing concerning or alarming. For all we know everything has been fine, except for the issue in 2015.

 

We are taking it in to a transmission shop to have it looked at before it becomes really bad. Just wanted to see if anyone else out there has had these kinds of issues...and can provide some insight as to costs, etc, so we can brace ourselves. :)

Has the transmission fluid ever been changed on your Edge? That is a vital service, and considering the (relatively) low mileage on your Edge, should really be changed under the Special Operating Conditions schedule. Even under Normal Operating Conditions, the Ford stated schedule is way overly optimistic, unless you drive 99% highway (maybe). That's where I would start.

 

What about spark plugs, coils and PCV valve? Many transmission issues actually are due to misfires or a poorly running engine and a dirty MAF sensor/throttle body. Once the engine maintenance is brought up to date (much cheaper to start there), then we can start attacking possible trans issues. Since the "putter" is around the area of torque converter lockup, that could be an issue. Or it could be a bad wheel bearing, though usually there is noticeable drag/noise accompanying it. Speaking of which, check the brakes as well. The rears are especially prone to sticking if not lubricated regularly.
