P1768 Transmission relay output always off.

First check the transmission fluid level and condition, make sure its proper. There is a fuse in the engine juction box that fuse 5 which is a 30 amp fuse,make sure that not open,there is also a relay,you can swap it out with a different relay like the horn. Here is your situation something turns off the relay, either you lost ground or power.
