Ok found the clutch reservoir, was full to the point it leaked when opened (had to use a plumber's pliers)
Liquid looks clean and transparent...
I couldn't see the reservoir initially as it blends with the firewall and other parts, being black...

Hey LuluBelle
I did the same looked up when forum said I joined and went , n waaaaaaat?

Good point. might mean one or both things
either this forum is awesome ( which it is!) meaning you get answers to pretty much ANYTHING if you know to search
And/or
The creepers are so reliable that one might just not need to ask...which the are.
So believe you ne, wasn't easy to post but humble pie half eaten, don't have no place to ask or take no more...
Not happy, not proud, it is what it is.
I'm fluent with my 4.0 auto ZJ with 240k, done Simpson twice, done Walker's crossing twice, went to Perth and back via my dare Uluru and great central, than back through Nullarbor and Moree.
Wouldn't have easily asked mates if I wasn't to the ends of my whits with this particular xj.
I got a good trusted tranny guy, I'll call him tomorrow, this takes priority over lack of cojones uphill..

QLD has more XJ Diesels than any other state in Australia so there is a better chance of finding a good mechanic there. I would never take either of mine to a Jeep dealer. VM made their name in marine engines & then industrial applications. The Xj engine was an industrial engine supplied to jeep. you may wish to talk to mechanics that do work on diesel boats. Once you understand the engine its not so complicated. Your knowledge about the petrol jeep is probable a hindrance. The manual trans is used in other applications, IIRC some jap stuff. its a very simple 5 speed manual box. Interestingly its a 1990's style box. As yours is not making noises, chances are your problems are only minor. If I dont push the clutch peddle down far enough either of mine wont go into some gears. it is also possible that your master/slave is on the way out & when warm is not putting enough pressure on the clutch. Been there done that! If you pumped the peddle up & down did it go into gear?

If there were aftermarket iron heads for the VM, i would have fitted them years ago. The heads are the weakness.

When some one with experience with these posts something, best not dispute it. I have 2 of them & over 300,000km driving/maintaining them. i think I would know if they had a cat. My manual has no mention of a cat in the diesel section. The 2 most knowledgeable members, Mudmonster & Dieselweasle dont post any more & may have left AJOR. While a few petrol XJ owners may offer help. They have very little knowledge of the engine & gearbox & seldom can offer much other than moral support. Many owners manuals & parts books have mistakes & are meant for the 2.5 petrol. Info from the USA is unreliable as it was never sold there. Never listen to the people at supercrap. Their parts info is nearly always wrong. They even tried to tell me there was a non turbo 2.5 XJ diesel. Triton info is also normally wrong. Much of the Crown (USA) is wrong & meant for the petrol 2.5.
Most parts I get from Europe. The engine was used in many other cars including Alfa, Rover & Ford there as well as things like street sweepers & other industrial things. There is a Facebook group for the VM engine based in Europe, the members are very helpful but you will probably find them to be old school die hard diesel people.

Also, I get your point re catalyst converter, but the factory manual describes one for the 2.5, unless it's possibly in the context of a petrol.


I do have the fsm and a separate pdf dedicated to the ax-15.
I tried to look for the clutch fluid reservoir and I can't find one.

While I respect your knowledge gentlemen and your helpful suggestions, and while this is indeed a manual and a diesel which I'm not familiar with, I'm not totally incompetent when it comes to mechanical work.
I do everything on my ZJ myself, I've done two head gaskets, replaced power steering pump, managed to fix enough to limp it to the nearest sealed road twice, once on Teewah and once at Poepples corner... Nobody helped me, and the head in the ZJ is solid iron

saying (words to the effect) he would not be answering questions on here anymore

There was another post here by Luminol related to gear shifting issues .
It sounded like the clutch master cylinder needed bleeding but he never came back to let us know to confirm it .
Croitoru... don't despair , just take it easy . Pull apart things and examine . You won't get answers that would pin point how to solve your issues just suggestions . People here assume that op's get dirty and rip in to it until problem is resolved . You sound a keen guy not afraid of oily hands and therfore I would say don't be afraid just rip in to it bit by bit and be calm ,don't rush .

Hi
Finally life gave me a break and took it into my trusted transmission guy, Clint@Hart transmission in Brendale (thank you state if Queensland for Ekka break).
I had to drive there in second, of course.
Then he took it for a spin and managed to shift it in 3rd, 4th, 5th, multiple times. By slightly pulling the shifter up.
He said there's likely nothing serious.
I'm going to ask him if he knows any good diesel mechanic up this way.
I will post results re transmission final root cause and fix as soon as I have it.
Cheers,
R

Regarding the gear shifting : It is very easy to remove the gear lever unit from the gear box (from the inside of cabin) . Remove center console , remove the rubber cover edges and push rubber cover up the lever .
There will be as far I remember 4 bolts to remove and the lever should come out. At the gearbox end of gear lever there would be a small plastic type coupling (squarish - that was broken on mine).
As you select the gears the coupling slides and moves the gearbox forks inside . Maybe it's worth looking at it .
That would be pretty much all you would be able to inspect the rest would be to do with gearbox internals .

Amlay - thank you.
Turned up it was the plasticky thingie you suggested... but wait, there's more!
The selector fork was funked, deep groove (aluminium) which explains the shiny look if the first gearbox fluid change.
And while at it, the clutch was kooked as well, also clutch springs broken... also seals ( including rear main)... rear lsd rebuilt (broken metal bits floating in the fluid, cracked gears, etc)
So a lot replaced and Clint reckons drivetrain good for 200k km now...cost, better left out of the discussion. He's really good so he cut me a deal. Took it for a drive up Mt Glorious today (and have been driving it daily for a week) all good, still a heavy manual truck. Climbed and drove fine as long as I kept rpm bellow 2k.
However...I asked Clint and he took it to a diesel specialist mate at the same time, but no cigar. No codes, tried egr blocked/unblocked, etc. It's clearely fuel restriction above 2000-2100 rpm. His mate scratching head, said either injectors or fuel filter.
Not sure what to do next, I guess fuel filter (no idea how old/condition, so might as well)
The more I drive it, the more it feels (of course could be placebo) that it gains just a bit more rpm before it starves.
It's clearely a fuel delivery problem because I drove behind it in my ZJ and I can see very little and very seldom any smoke even when downshifting on climbs.
It FEELS like an electronic sensor problem, restricting fuel at 2k+ RPM.
