715 is a transmission code. It needs a shop with a scanner to monitor the sensors and find out the issue as to why it is lighting the check engine light. Nothing you can do at this point.

You don't necessarily need to take it to a tranny shop or a dealer. You'll just get more frustrated. Find a mechanic buddy and replace the input speed sensor. Might as well replace the output sensor also. $20 ea.
Just Google 2002 Town and Country transmission problems. And you'll see what I mean.

Having the same problem with a 1999 Town and Country Limited 3.8 liter. PO715 and PO700. Think its called "Limited" because there is a limited number of days until the next problem developes. Think I'll change an output sensor, but I suspect an electrical voltage problem. I'll have the battery tested tomorrow. Let me know if you have any luck. Thanks.
