Hi All,

After many months, my brother finally got his montero out of the shop and had been driving it around infrequently between visits. New fluids, new front end, new shocks, new cv's, Aisin manual hubs, engine work, etc, etc.

With the winter weather finally upon us been using 4h a lot. Suddenly noticed a gradual loss of 4H in the past day. Started out fine with full engagement every time and no power loss. Over time there has been gradual loss of power most notably from city stop and go traffic. Now no power transmitted to ground in 4H. We've tried the other modes and no issues at all. Currently using 4HLC albeit limited.

Did a search and we don't have the flashing light, no grinding/gnashing noises. We've tried sitting in Neutral and shifting, shifting on the fly, rolling forward and back...nothing. My brother is coming by after work to have me look at it. I haven't found much in the tech/archive regarding this issue. Any ideas? Thanks in Advance.
