The difference will be like chalk and cheese, you'll wonder how you lived with it before. Be careful though, you'll arrive at your first few corners 20 mph too fast.
The truck is new to me and the transfer ratio was hell -- top speed of 60 or so. It also over taxed the already failing radiator, which is now with Pendy to be built into a full-width with a full-width intercooler in front and a standalone oil cooler. My hope is that with all this and a the 1.2 xfercase that's going in I should be fine for highway driving.

going to start stripping the new case tomorrow.

Make sure you remove the solinoid for the shift interlock.

Errr.... which one is that? I just stuffed the replacement one and drove off into the sunset, literally.
What do I need to remove, what's going to occur because I haven't

Not sure if it is on a DII case, I think it is, but it is the round tube structure on top of the case with the wire coming out of it. There is a solinoid to prevent you shifting from high to low unless you are in neutral.

Hmm... so if it's not wired up it shouldn't do anything?

If it is not wired up you cannot shift into low at all.

It is in the round thing on top.

Yep .... that's the bit on top, someone must have disabled it before I got the transfer box. It's not wired up but I can select low range. I feel a little ivestigative spanner work is in order this weekend

Mike, yes, I'm going to turn up the fuel a bit to take advantage of the intercooler.

Ordered the seal kit RTC 3890 for it, any pointers on it. This is my first time messing around much at all with the transfer case, so all of the help is much appreciated.

Tony

check the drive flanges for a groove where it runs in contact with the seal, that's where the leaks occur. you can polish out a slight groove. also you can adjust there the seal sits slightly.

I'd open it to make sure everything looks fine in there (no chunck of metal and other foreign object).
As long as you don't start disassembling the gears / splitting the case in half (should I say "third"? ;-) ), you can't do much arm.
I'd replace input and output seals all around just because you have it out!

Good ideas, thanks. The seal kit appears to be very comprehensive, I'll replace as many as I can identify. Loic, I'll absoutely pull the inspection plate, good call! Ray and I are tackling this on Sunday, we'll report back afterwards. Unless we really eff up, in which case you won't hear another word about this . . .

With a lot of help from Ray, we got the case resealed (save the PTO cover and cracking it in half), pulled the inspection plate (looked perfect) and removed the solenoid. Took all of an hour including several beer breaks. Now to get it installed.

Make sure you use a transmission jack to re-install it or you have a good chance of messing up the seals (those suckers are not heavy duty! ;-) ). But I'm sure you knew that already.
Sounds like you guys had fun!

Follow-up Post:

Before I forget: I bought (can't remember where.... RN? EE?) plugs to put on the diff case/transfer-case/etc with a magnetic bit that, I think, will help in the long run. Since yours is likely without oil right now, then.... you might want to do that too?!

My rig is likely on the way to either the head gasket needing to be replaced (again) or a slipped liner-but the bigger issue at hand is that I don't intend to deal with it since we were already going down the diesel path anyway, this just gives another reason to push that along. Since A procured herself a MB 300D as a DD we're rolling three cars-hence Tony rocking the Disco for a bit while the 110 waits to be upgraded and returned to the road....hopefully the Disco doesn't blow up on him between his house and Clarendon.

Change the seals on the TC was interesting-that thing clearly was in a DII that never went off road. Tony did all the work, I put myself in charge of drinking most of the beer.

Doug-
Diesel Disco...at this point I've got enough into that truck (and enjoy it's quirks) that I want to follow that path. The Defenders are sorely tempting but I'm 99% sure I'm sticking with Coyote.

There's a thread on discoweb (http://www.discoweb.org/forums/showthread.php?t=53043) that is currently discussing the inability of the later LT230s to fit onto early auto boxes (the thread is specifically referring to D2 xfer cases fitting onto earlier RRCs). So just to revist post #1 of this thread (and to avoid considerable stomping of feet in the future): is there a spud shaft length issue in fitting a D2 LT230 onto a 300tdi R380?

Thanks
