Transmission issues
 

My sister's '99 Concorde check engine light came on and she noticed a little difference in shifting. I checked the PCM with anActron scanner an received the following codes:
1st = P0733
2nd = P0715
3rd = P0700
4th = P0700
Does anyone know what might cause this or has had the same codes and know a fix. She has limited funds so if I can fix it for her and foregothe dealer it would be a good thing. The car has been well maintained w/61,000 mi..
Thank you for all suggestions and experiences, Dave

P0733-GEAR RATIO ERROR IN 3RD
P0715-INPUT SENSOR ERROR
P0700-INTERNAL TRANS CONTROLLER

sounds like speed sensors to me replace both input and output 30 bucks each they are outside of teh tranny and screw in.

Thanks for the advice. I only replaced the input sensor but that seemed to do the trick. Dave

I currently have a 97 Chrysler LHS. The transmission went into limp-n mode and threw codes 56, 57 and 28. I changed both input and output sensors and still get codes 56 57. After installing a new MVLPS I now get a code 24 and 28. The shift lever also moves out of Park w/o pressing the brake pedal.

I double checked all ground points and they are good.

What's next? TCM?

Any ideas please let me know.
