Hi Papa Many thanks for your reply Can you advise where I may locate the relay or sensor, the problem seems to happen when easing off the throtel between 100 - 80 kms. This happens about once a month, and only if decreasing speed quickly

sensor should be on side of tranny.their is a small motor on back of transfer case unplug it,see if that stops the problem.or may be the problem,with it unpluged it will not go into 4x4.another possable problem could be the push button switch for the 4x4 is bad.unplug the small motor first.

Mark helpful, what do you call that small motor you can unplug? Thanks, Kay Need to Know
