Have Transmission Questions? Ask a Mechanic for Answers ASAP
Did you still need help with this?
It's nothing I've heard of or seen before. The 4wd system on these vehicles is usually pretty robust. You might try resetting the system. This would involve removing the battery cables from the battery and then holding them together for about 1 minute. This clears the memory from the computer systems. Then hook the battery back up like normal. If it's just a stuck module then this should get it to free up. Otherwise something may have broken inside the transfer case.
