I've spend a couple hours doing a ton of searching of the forum and learned a lot about CDL with different model years Disco. But what I need to find is some info about my options specifically with an 03.

I'm not planning on rock crawling but I would like to play light to medium off road "games".

Also the truck is in need of some work anyway- rubber, brakes, drag link, track rod, window reg, etc,, so while I'm digging in I might as well do some upgrades while I'm at it and make a project out of it.

If I want to add CDL should I buy a used part from an 04 or previous year like 01?

Are they all compatible in terms of mounting and other components like drive shafts?

What are my interior options for a shifter?

Is this all worth it in terms of time and money?

I already own the rig so don't bother suggesting buying a different model year... For a while I need to either live without the mod, or jump in and do it. That's the decision to be made.

 

I did some more searching on the web (vs just on this site) and found a lot more info.
Looks like essentially your options are:

1- Buy an older TC (pre-02) and install with either old style LRvr linkage shifting or newer (04) style LRvr cable shifter, or aftermarket shifter from Ashcroft.

2- Buy a newer 04 TC and use an 04 shifter

3- Convert your 03 transfer case to locking.

Here's a link for option 3 in case you have an 03 and are considering this...

Here's some other links that I found with main web search...

You have limited options, either install a t/case from a 04 along with its cable linkage or buy a used CDL nose assembly for around $150 plus either a D2 mechanical linkage or an 04 cable style linkage.
How mechanical are you?
Do not plan on using a pre-03 t/case because they are different in length and the electronics are also different.
If you have any questions, PM me your number and I'll be glad to walk you thru your questions.

 

Thanks Mike

 

Hey Mike. PM'd earlier. Give me a call when you can. Trying to decide which way to go.

Thanks.

All LT230 are the same length to the best of my knowledge. The transmissions on the other hand are a different length.

 

So an 2004 T-Case and linkage will fit directly into an 2003? Would you have any other modification you will have to do was far as wiring?

 

Wiring depends on when it was built I think. Some people have found a harness tucked above the frame rails that they could plug in, but probably most 03 owners have had to tap into the harness and run a couple of new wires.

 

I did the installation a couple of months ago. Installed a 2004 assembly and shift linkage. Best modification which I have done so far for my Disco. It is definitely a plus if you intend to do some off-roading.

I recommend going with the 2004 cable linkage (instead of the D1 rod linkage version).

 

Just call Paul Grant, he most likely can provide you with everything to make this a smooth upgrade. I bet he can even tell you every bolt size you will encounter.
