I purchased few weeks ago 2004 T&C LX with 74000 miles from Ed Voyles Chrysler in Marietta. After driving some 800 miles the check engine light turned on. I checked the codes with power on-off cycle and ended up getting P0700.
The whole story is as follows. Our driveway is steep downhill, so when leaving the house we have to back up very steep for some 40 feet. And most of the time the car is parked on this slope, nose down. Yesterday the fuel tank was very empty and we left shopping. After backing up the check engine light came on with a beep. I though that it might be because of little fuel and akward position the car was for last 10 hours. I filled up the tank but the light stayed on. Then minute after leaving the gas station the car stalled at the traffic lights, the engine just died. I started it again without a problem. And it has not stalled since, but the light is on.
I have no previous experience how T&C should feel like being backed up steep hill etc, so I amnot sure it should feel. But to me this car feels heavy going up, it is not like any sedans I have had on same slope.
Now, it came to my mind that there was some sort of hesitation (and noice?) from front when we started going forward after backing up. Like front tire scuffing on wheelarch as I had the steering full lock to left, so I though no problems. May be something really broke... yikes... There has always beenslightwhine from somewhere, and the whinegoes higher (and away) when rpms rise, and on idle the sound of exhaust is sometimes little bit like lazy V8, not that low though...
What could be the issues with transmission?
As the car has some sort of warranty for engine and transmission for 2 months/2000 miles I guess I need to take it to them.

First off, you shouldn't be paying for a flash to fix a problem unless the dealer can show you a TSB (Technical Service Bulletin) identifying your problem and prescribing a flash to fix it. In other words, if Chrysler didn't design the software update to fix your problem, it's not going to.
As for the P0740, this is most likely a worn out torque converter clutch. In theory it could be a hydraulic issue, but the converter clutch is a common failure. Unfortunately, it requires removing the transmission to replace.
