I've driven a '97 Explorer with Control Trak for years. It works well and I especially appreciate the ability to lock the transfer case in poor conditions providing an immediate improvement in traction without waiting for a wheel to slip.
Our new (to us) '08 V8-AWD Mountaineer has a less accessible function reached through the info center that reads AWD Locked or Unlocked. Just what does that do? Is that a way to lock the transfer case? Neither the owner's manual nor the shop manual provide any enlightenment on this.
