I've mentioned this in other threads lately, but I'm hoping someone here has experience with this.

My transfer case shifter will not work when I reach normal operating temperature. I was told by an LR mechanic that there's a solenoid switch that may have become heat sensitive, or is failing due to heat somehow.

I don't believe the linkage is frozen because it shifts quite easily when the engine is cold.

I really don't want to pay the LR labor to replace it so I'm hoping to find out more maybe from this board. Maybe I can remove it completely - or disable it somehow? I can't see it from underneath - or at least I don't think I can. advice is appreciated.

Kenny - tired of having no LOW gear when I arrive at my offroad destination

First question:

Are you still covered under warranty?

It doesn't sound like you are, but I thought I'd still ask.

No warranty.

That's a tough one then.

I'll have to take a look at my shop manual for the D2. I do know that there is an interlock solenoid in between the hi-lo range detents on the transfer case shifter, so at least the mechanic's explanation sounds legit for the time being.

I'll take a look and let you know what I find.

Thanks Koby,

That sounds interesting because the mech said that it was to keep the shifter from being manually shifted from underneath - avoiding a theft by tow. I appreciate your feedback - I guess I'm going to need a shop manual!

It prevents you from removing the key with the t-case in Neutral. I think it's only found in the NAS and Japan markets.

Kenny-

Check your mail, I'm sending you some reading materials.

Al-

You are correct.

This rocks,

Thanks for the help. Now we're challenged with getting to the actual solenoid! The LR mechanic told me it wasn't easy to get to - it looks pretty tight up in there.

Kenny

P.S. Craig sent me images from his manual via email. That's what makes this board totally awesome.

Update:

With help from my sons, and some suggestions from our local LR mechanic, we managed to remove the bad solenoid and instead of replacing it, I cut off the "plunger" for lack of a better word using my dremel tool (I don't want to buy another solenoid and I dont want it to fail again). With the modified (non-working solenoid), My transfer case can only be shifted when the key is in and the main shifter is in neutral. But now it will always shift instead of failing when the engine warms up.

The most difficult part was removing the solenoid cover on top of the transfer case. We had to go in from the top, removing the console and drilling the rivets out of the metal plate that the shifters mount on. The cover for the solenoid was quite difficult to pry loose and the tight quarters made it very challenging to get tools in there.

All seems well so far. I'll be keeping my eye on the transfer case for any leakage (I did reseal the cover on using a high temp silicone, so let's hope it stays sealed).

Thanks again for all the help provided on this board. I doubt that I'll be taking my D2 into LR anymore as I'm officially back into self service!

Kenny,

I just performed the EXACT procedure today! Now I can get low again and you were right, there is a solinoid on the D1 96 and newer. Thanks for the help on the last thread.
