Help! problem with check engine light trasmission codes

I am posting this in the intrepid forum as well, since both the concorde and the intrepid are so similar. I relly could use some help!

I am trying to figure out some check engine lights on my parent's 98 chrsyler concorde lxi. It has a 3.2 with 35,000 miles.

It threw the following codes,
PO731, PO734,PO715, PO700 (twice on the PO700)
I know what the haynes manual says, but I am not sure what these indicate, or where to start.

I cleared the codes out, and got similar results,
PO731, PO733, PO734, and PO700 (twice again)

THe car feels like it doesn't want to shift out of 2nd or 3rd. It has little or no acceleration, like it normally does.

Previous to this, in the last 4 months, we replaced the output speed sensor (pretty sure it was the output) when the trans wouldn't shift out of first, and the speedo didn't work

Also, the car was serviced about a month ago for a bad trans into the radiator line. (hmmm. only ~35,000 miles.... odd?)

It runs great otherwise, and has me baffled, any help would be greatly appreciated!

Thanks!

visit this site (http://www.automotiveforums.com/vbulletin/showthread.php?t=355082) for a definition of your codes. As you may be aware, those codes are transmission codes. Hope this site helps

Follow up....

My dad replaced the input speed sensor, and it seesm the old concorde is running like a champ. Just wanted to post some follow up, in case it helps anyone else.

BTW, we originally bought both sensors, and he opted to only put one on... I told him to put both on at the time, but he didn't listen...

Oh well.....


Best!

I would highly recommend that you have the other sensor replaced and have the dealer reflash the computer code- also at 35K miles you state, change the oil and filter on the tranny, adjust the bands if needed- I had it all done for $185 at the dealer- don't neglect this tranny-
