The trans in my 2008 AWD has been chattering or clunking going at a slower speed, maybe around 40 mph as it tries to upshift. If I press the pedal down hard - no more problem. So last night as I was beginning to go forward after a traffic light turned green, the engine reved very high and the car was sluggish to get moving - almost like the trans was slipping - but once I reached about 30 mph, it operated normally. But started very slowly every time I had to stop. The little wrench indicator was too. This morning... car ran fine. No service light. What is going on?? I read on this forum about a OSS(?) sensor in the trans that has a reputation for going bad, but my symptoms don't sound exactly the same. How can I read the codes?

I have a 2008 Edge SEL AWD and up until 7 months ago I had no trouble at all out of the vehicle. I've owned the car since 2010 and it had 50,000 miles when I got it. I had the Transmission Services at 100,000 miles, but around 107,000 miles while driving down the highway the vehicle seemed to lose power, all the lights started flashing on the dash, speedometer went to zero, odometer turned to lines, etc. To make a long story short took the car to the Ford dealership and the TSS and OSS sensors were replaced and the car drove great again for awhile. I will point this out before the dealer checked my car and I told him what was going on he said 'well with that amount mileage it may just be time for a new transmission.' Not sure if it's just me but replacing transmissions at a little over 100,000 miles is not normal. I have a 2001 Pontiac Grand Prix Supercharged with 205,000 miles on it and the transmission had to be replaced at 201,000 miles. Anyways, about a month after having the the sensors replaced in the Edge I noticed the car was slower to take off from a stop at lights, it also began to jerk and lose power going uphill. So in October I had the spark plugs changed and the jerking and power loss uphills went away, problem solved. Now my issue is the still remaining slow take offs from stop at lights and occasional clunking when going at speeds of about 10 mph. I have noticed with the slow take off issue my RPM's would go up a little higher as if my shift points are off but never over 3500 rpm. It's possible the car is taking off in a higher gear, I'm not sure because I'm not very vehicle mechanics savvy. I plan on taking it to the dealership to get checked out but I'm afraid it'll end up automatically being a worst case scenerio type of situation with those guys. I'm just wondering if anyone can spare a little knowledge or insight from experience with this type of vehicle, so that I know what to say to the service advisor. Also, I am wondering if having the PCM reflashed since it's never been done (atleast since I've owned it) would be worth it or possible considering the vehicle mileage. A little more information about my vehicle: It now has 115,000 miles, the current issue has been the same from the start. I just noticed one day take off was slower and rpm's/shift response a little different, it hasn't gotten any worse nor has it changed in anyway. It's as if this is a normal behavior for the car, but I know it is not. Also, the service engine nor any other warning lights have come on, not even when the spark plugs were causing the jerking problems. My vehicle had a 100,000 mile warranty so as you can imagine I'm pretty sad that all this is happening now.

2007 ford egde having a transmission issue. Every once in a while it would have a slightly hard shift, ususally when accelerating fast to merge into traffic. But earlier this week it completely stopped working after stopping at a stop sign. Aftrer turning off the car for a few seconds I turned it back on and it engaged very rough. After that it wouldn't shift out of first gear. The engine RPMs were high and my speed was low. It felt as if it was slipping. If I kept my momentum up I could drive about 20-30, but if I had to stop I would have to turn the car off and wait a bit until I could continue on. The really odd thing was after sitting and waiting at a light about 2 blocks away from Aamco shop for a minute or so I turned the car back on and for those last two blocks the car acted normal. I was able to accelerate up to 50 and the car shifted normal. I pulled it into Aamco and later that day got a call that they couldn't get the car to move at all. They didn't find any codes, my fluid was at the proper level but smelled and looked burned (says the shop). They said they should do a rebuild. My question is what would cause these semi-intermittent issues where it would drive normal after sitting off for a while. I have the transmission apart down to the OSS and TSS sensors. (There were several small metal shavings attached to the TSS sensor when i pulled it out.) How far should I tear it down. What else should I be looking for? I would rather find the cause and fix it myself or at least verify it needs a rebuild before spending 3Gs on it. Thanks in advance
