2000 sonoma tccm

i just recently replaced the encoder motor. everything workd fina at first then it wouldnt go into 4wd hi. i unplugged the battery and recet the tccm. it worked fine for a lil while then the same again. as long as i unplug the battery for a while i t will work temperarily. does this mean my tccm is bad if i have to keep unpluggin the battery to get it to work? how much is a new tccm?
