I am not a mechanic- nor even mechanically inclined- so take with grain of salt- this is only my experience- yours may be different. With so many problems I was shocked to find no one posts any answers.
My 2004 Chrysler Concorde 2.7 with 76, xxx miles - latest problem: check engine light on- drives fine. Makes bad sound when first start with cold engine. 2 seconds and sound is gone. If restarted no sound. Codes:
P0700 Generic indicating transmission problems,
P0732: Gear 2 Incorrect Ratio;
P0871: Transmission Fluid Pressure Sensor/Switch "C" Circuit Range/Performance-
These codes 732 & 871 would indicate the the solenoid pressure switch assembly above the valve body which is accessed by removing the valve body through the transmission oil pan(from what I gathered from the internet. My $75.00 code reader didn't pick any other codes up.
I changed transmission fluid and filter- Still same codes. So I finally broke down and took it to a mechanic, I told the mechanic the codes- I figured if he don't know what they mean then I don't want him working on my car. If the first this out of his mouth was a rebuild same thing. He did know what they meant and said that they were probably the solenoids above the valve assembly. So I said ok let's get started. He then hooked his code reader up and an additional code was found:
P0944 Hydraulic Pressure Unit Loss of Pressure.
Bingo- that would explain the other code problems- transmission oil pump went bad. Had to replace- Simple? Na- have to rebuild the transmission and replace the solenoids while at it. But I'm ok with that- That did appear to be the problem and it was not just the first thing out of his mouth. I believe to have gotten a good deal at only$1,400.
Again I'm not a mechanic - this is only what happened to me- I hope this helps some one. Good luck
