First time poster, so I hope I'm in the right place and following proper forum etiquette here. I'm a long time Ford guy, but usually stick to 50's-70's stuff. However, the dd's are relatively new, and I'm having transmission issues with my wife's 2007 Edge SEL (FWD, with 3.5, has 155k on the odo). I apologize for a lengthy post, but I'm trying to be as specific as possible for a diagnosis. About a month ago, I noticed the Edge was really hunting at shift points (when at operating temp). Cruising speeds were running about 750-1000rpm higher than normal (mpg's dropped about 5-6 points) (this was consistent whether hot or cold). The vehicle wasn't holding speed very well while cruising (at operating temp). And finally, what made me bring it to the dealer was, after 30-45 minutes of driving, with cruise control on and set, it wouldn't hold speed on an incline. So I tried manually giving it gas with cruise still on, and I had absolutely zero throttle control. Through this entire process, I could not get the vehicle to throw a single code. I read several forums that pointed me in the direction of the TPS (and while swapping sensors, might as well do the OSS and ISS, I believe they were called). I didn't want to just throw parts at it, so I suggested those items to the dealer. The dealer pretty much shot it down and I'm not even sure they tested. When they start their diagnostics, they say the only code they can get is that the trans was operating too warm. Said it was operating in excess of 250* and less than 220* is spec. They say 'the valve' and 'some lines' were sludged up, causing the excess heat. $400 later, 'the valve' and 'the lines' were replaced and the trans is now back operating in the normal temp range. So I got the Edge back Wednesday. The dealer tells me the symptoms are fixed...but now I have an 'intermittent whistle' that they don't know what it is, and will require $2000-4000 worth of 'exploratory surgery'. Tell them, I'll drive a 9 year old vehicle with 155k on it in to the dirt before I pay 2-4k for a problem that no one can even diagnose yet. They said they understood, and it could last another 150k, but they just don't know. So I get in the car...almost immediately I hear that 'intermittent whistle'. It's acctually a pretty consistent whine between 2500-3500rpm between 45-60mph. Almost sounds like a power steering pump whine coming from my trans...or maybe an actuator hunting for engagement. Definitely much more pronounced as I'm getting off the throttle. Turned O/D off to see if that had an effect, it did not. Beyond that, I won't say the vehicle is 'right'...but the original symptoms I brought it in for are now gone. I should also note, this is a podunk town, where I get a 15% discount from this dealer every time, because I have more pre-97 Ford literature and manuals than they do, and they call me from time to time for help (I'm a finance guy by profession). So I apologize for the lengthy post, but that is where I stand. I'm pretty proficient with a wrench, I just need some guidance. So thoughts, opinions, suggestions are greatly appreciated.
