I found this video from Ashcroft Transmissions, regarding transfercase failures, ultimately leading to transmission failures. Its interesting and will definitely effect when I lock my CDL off road, and how much I allow my wheels to spin. The interesting part starts @ 1:00. Moral of the story is don't allow to much wheel spin. When off road in slippery, low traction situations, lock the diff. The video states 5-10 seconds of varying power i.e. wheel spin in front and none in rear without the center differential locked could blow the center differential. When center differential is blown it acts as if its always locked, then your transmission will fail quickly.

For what it is worth, the ZF 22 and 24 are nearly bullet proof and as long as you service both the tranny and t/case you won't have a failure.

This information is very important if you have the ability to lock the centre diff. Otherwise, like me, you have to hope that the traction control is working correctly.
One of the first major mods I will be carrying out in the new year is the fitting of an aftermarket diff lock linkage. Together with traction control this should increase the trucks off road ability loads.

So you're saying Ian Ashcroft doesn't know what he's talking about?

Let me put it back to you Tom, how many tranny/t-case failure have you seen that have all failed per a common cause??
As the possible t/case issues, there are a number of LT 230 t/case some worse then others but the D2 is pretty strong.

I would say yes mike most transfer cases have failed due to commons causes, leaking fluids, neglect, etc. but you can fry the lt230 t cases with excessive wheel spin, it was just something to warn others from potenitally frying their tcases.

Dane, you have little or no experience with Rovers in general so don't come across as knowing and maybe just deal with your many questions and threads regarding your truck.

Amen Mike.
Dane..... Reality check time! What you have read about and what you have experience with are 2 entirely different matters I think.
As I have little experience with L.R. Transfer cases - even though I have been in the auto service industry as a technician for 30 years, I will take the information and not add my 2 cents how many years have you got Dane?

Redtruck, this is a reality check for you. This information is from the video from Ashcroft transmissions, in which a company in which deals almost entirely in Land Rover drive train. None of this is my opinion at all, this is all from an experienced technician who works on Land Rover drive train every work day. And Im sure glad to hear you have 30 years of experience in the automotive industry but don't know about your own truck, that's great, admitting you don't what the **** your talking about, and trying to further insult me, go **** yourself. As for me, yeah I have little experience, but I turn to others for help via the forum, and yes Mike I do ask a lot of questions, but I ask to learn and to do something correct the first time, because I respect those opinions on this forum who have vast knowledge regarding all Land Rovers whether they are correct or not, that's what this forum was for, helping others and communicating through a common interest, not this petty bull **** back and forth arguing. Mike, I respect your opinion, but not your self entitling bullshit attitude you have.

First of all… If you're going to b!tch and berate, then paragraphs, correct grammar and spelling, and complete sentences are your friend. Second, some things are left better unsaid…

I'll say this. Forums are both an excellent and terrible resource. People often consult forums for answers to problems, but rarely to give praise for components without issue.

Virtually no one posts to a forum to say they've had no problems with a particular component. The same is true for a repair shop. No one takes their vehicle to the shop to say, "Hi, I've had no problems with my vehicle, it runs great and needs nothing. Would you like to find something wrong and charge me to fix it?" Given that, of course a repair shop is going to say they "see a pattern" or "a common problem." That doesn't necessarily mean the component has a high probability of being faulty.

I don't know much about the Land Rover transfer case. I will say that I've had plenty of wheel spin and never a transfer case problem. Given the LR traction control, I imagine that it's pretty rare to have a front axle spinning while the rear is static.

Here's the real question though. What are you trying to improve by posting the link to the Ashcroft video? Are you trying to point out a flaw with no solution? Clearly, there is a solution that is frequently documented on this site (install a locking center diff.). Perhaps you're just trolling?

Why tell me that things are better left unsaid directly after you insulted my grammer. lol. Also, I don't think you fully understood the video, let me explain in case you didn't: The transfer case itself with the CDL does not fail, the CDL mechanism fails, when it fails the transfer case acts as if its locked, stressing your transmission. I was saying, for those who have the CDL equipped transfercase, (99-01 and 04 discovery II's) lock it when off road. I was not trolling, I was trying to inform the other Land Rover owners with the CDL equipped transfer case who intend to use their trucks for off road purposes, should remember this video and learn from it. I was not trolling.

Put it back to me? You mean "I'm not going to answer your question", right?
In any case, who said they all fail for the same reason?
There's a reason it's common knowledge to not run substantially different size tires on the same axle.

As for your implication that Ian Ashcroft doesn't know what he's talking about.
These are full time 4WD. Different sized tires rotate at different speeds. Having your front tires turn at a different speed than your rears on a 4WD vehicle is a recepie for disaster!!!!!
Ditto
Make up your mind.
