Check Engine Light
 

I just got back from the dealership and they did a diagnostic test to see what why our check engine light is on. The codes that came back are P0715 and P0707.
My question is: How urgent is it for us to have this fixed. We were planning on driving the car to visit some family. It would be about a 600 Mile drive there (and of course another 600 on the way back). The parts may not be here in time for our trip. Is it bad for us to wait till we get back to have the codes taken care of?

0715 is the input shaft speed sensor... get it done, as it will cause you fits with goofy shifting and start out in wrong gear..

0707 is inhibitor switch, can drive, but will need replace.
