Trust me... I don't like starting posts before I search it first but I still need help

I got the code P1870
"Tranmission automatic 4-wheel drive indicator (lamp) circuit short to battery."
"Tranmission mechanical transfer case 4x4 switch circuit short to battery"

From doing a search I've read it's the control valve body.... my question is... Is is still safe for me to drive it home (interstate for about 55min.) this weekend or should I try and fix it. Last thing I want to do is buy a new tranmission right now.

Can I drive it is or should it be replaced asap?

Thanks

 

as long as it isnt switching in and out of 4x4 then you'll be fine if you keep it in 2wd---but get it fixed as soon as practical because that damn check engine light is annoying as crap! [8D]
