Trans Codes 0700, 0715 and others

[Jose Gala]

Hello,
It is a 1999 Chrysler Town & Country 3.8 L that suddenly showed the following errors codes
P0700: Automatic Transmission System Malfunction Detected
P0715 A/T Input Speed Sensor Circuit Malfunction

P0731 A/T Additional Gear Ratio Error in First Gear
P0733 A/T Additional Gear Ratio Error in Third Gear
P0734 A/T Additional Gear Ratio Error in Fourth Gear

It drives OK but the tachometer is moving around 2,500 and 3,000 instead of 1,500 to 2,000 as usual
Even the engine light went off and on a couple of times

I don’t know if this transmission part has the input sensor outside and if it is possible to troubleshoot it, at first
If it is a general failure in the trans, probably it would be worthless to work on it
What do you think?
Thank you in advance

see if this helps. The p0715 is the one we want.

Excellent article. Thank you very much and it encourages to do it by myself. At least, to try.
