from memory a gearbox oil and filter change should resolve it... I think there is a filter inside the ZF.

Oh dear:eek:

How many revs approx before it goes from 1st to 2nd? The theory is that contaminants enter the governor and cause this problem. You can change the governor in situ, but it is not a perfect solution.

A fluid change might mitigate the problem, it certainly won't hurt...

Certainly sounds like a sticking governor, and no they aren't an easy change. Transfer case off, extension housing off autobox and there it is. But I would do a fluid change etc first and try it as suggested.

Hi JC, I've read that it's an idea to do a couple of fluid changes (to try to drain most of the older fluid still caught up in the tc) if there's a problem like this...

Is this what you have found ???

Hi Laurie, I guess it depends on how filthy the fluid and the insides of the trans are in the first place. Both the ones I tried it on were pretty well 'unserviced' prior to this, IE the fluid looked like engine oil:mad:. One of them eventually had to have a governor replacement as it worked only in the short term, and the other vehicle was I think taken interstate so I couldn't comment on that one. Basically yes, If the oil is really disgusting I would do it several times, it can't hurt, as as you know the converter can't be drained and the volume of oil in them is quite a bit. Flushing the trans is possibly worth it, but I don't have one of those expensive flushing systems, I just drain and refill the trans and drive it, then drop the oil again and change filter etc and that is usually sufficient. Disconnecting a cooler line and running the engine etc is a recipe for another Exxon oil disaster:p

I was led to believe that the only definitive answer is a rebuild, as the problem will recur eventually because it is failing clutch packs that are depositing material in the governor assembly.

It's a precarious situation, putting in new oil [particularly a synthetic] could dislodge more contaminants and exacerbate the problem.

From day one the clutch packs are depositing material somewhere.

It is just an accumulation of such material which is the problem.

The propper fix would be a rebuild if the box is probably older than 250,000kms but I would try changing the filter and the fluid a couple of times first.

Mine has done this once after a trip up and down some narly big hills with Rangieman but a trans service and all is good.

Don't forget to have a 'Torx' bit, size T27, on hand to remove the filter assembly inside. Also, you may well have to remove the LHside gearbox mounting bracket off the casing to gain access to the LH rear corner auto sump bolt. It is held on with 4 x 19mm ring spanner size bolts. You will also have to remove the 2 x 15mm nuts under the gearbox mounts to lift the trans enough to slide the sump forward and downwards. There is no need to remove the crossmember with the Diesel autos, and it adds a certain amount of difficulty to the job by doing so.
Sump bolts are done up by hand quite tightly. They bottom the bracket out so stop there. DO NOT use an air ratchet on the T27's holding the filter on. If you strip one of these out you are in BBBIIIIGGGG trouble:eek:

It would not select 2 but only when cold and then after an oil change it got worse and would not select 2nd at all. Found out that the oil was full of water and the oil fileter had not been changed for years. Had to have a whole new box in the end

Yeah, water is the clutch plates worst enemy in an auto box.

Ive been told by my mate who used to be a builder at A & B that it takes about a teaspoon of water in the il to kill a normal auto trans (Borg 35/Turbo 350/Trimatic) but im not sure how much the ZF will tolerate, I wouldnt imagine it would be much.

Hi Jeep boy,

Remember to start the engine and run the vehicle through the gears, stopping briefly at each selector position. Then recheck the oil level on LEVEL ground idling in neutral. From min to max these take only about .5 of a litre, so be careful not to overfill it. Fill it to about the top mark while idling in Neutral, box cold.

Sometimes they take a while to settle to a level, so leave it idling for a little bit to check the level accurately.

Finally, go for a brief drive, say 5 or 6 km and recheck the level, it should be slightly above the top mark if the oil is warmish, say 30 to 40 degrees.

How much gunk, and what colour/ consistency?

JC

10th January 2009, 06:16 PM
When I changed the oil on mine, it took about 5 days of checking it each morning when cold and adding another 100ml each time before I got it to measure full consistently; so make sure you check it the morning after for a while,

Are you running the vehicle while dipping it? They can take around 5.5 litres as the pump housing empties when the filter is undone, but there is still a couple of litres in the converter that won't come out.

Idle in Neutral, check the dipstick. How far above the full line is it up the stick when cold, idling?

Hi, few things I learnt after having problems with mine. I got the auto box serviced in Sydney and it made it all the way up the coast to about 100km north of Cooktown when the sump pan gasket split and dumped all the fluid and burnt out the "A" clutch. The mechanic who did the job reckons it was a dud seal, the auto transmission gurus who rebuilt the box for me reckon he overtightened it causing the split. Either way dont over tighten the sump bolts and keep a bit of an eye on it for leaks!!

Not long after the rebuild I was checking the level after a short drive and found pratically nothing on the dipstick. No leaks and after a phone call the the "guru" again he told me to take it for another drive and get it up to normal operating temperature and check it again with the engine still running which I did and there it was, all ok!! I recently change the fluid again with similar results, to get an accurate reading the fluid has to be hot/normal operating temperature.

You would hope not but are you sure the Kms are genuine and you cant be sure how well the box has been looked after.

It sounds like a valve body problem, I wouldnt be too worried about the dip stick, sometimes they vibrate around at the bottom (with the vehicle idling) so you just take an average.

If it's holding 1st then it sounds like a govner problem, probably got a heap of crap in it but the slipping in and out sounds like either a sprag or clutch not locking completely.

How is your kickdown cable adjusted as this is critical to get full line pressure to your clutch packs and govner etc, it should have a bit of pressure on it, 5mm comes to mind so basically if you pull the pin and let the arm on the injector pump rest then set the cable to about 5mm back from that then pull the arm back (or the cable forward) and drop the pin back in.

Just play with the adjustment from there to get the right shift feel.

Be a little careful though as too much tension will break the end off the cable in the box and not enough can cause bad shift pattern and wear away at clutch packs etc.

..., to get an accurate reading the fluid has to be hot/normal operating temperature.

The driver's handbook says quite specifically that to get an accurate reading the ambient temperature should be 20C. In other words the gearbox should be cold. The dipstick also has the words "check cold" stamped on it.

It also says to check the level while the engine is running in Park. Have you had any luck yet Jeep Boy?

before i changed the oil it was perfect just took a bit to get out of first when it was cold, now it still does that but up hills its like it slips into neutral for a split ceond and back into gear than nuteral...... so im thinking maybe lfuid is low and up hills its not picking up fluid, when checking why does the car have to be running, im thinking it could be a sticking govenor, as for ks im pretty sure there genuine,

Compared to my cable that sounds awfully tight. My kickdown cable has about 5mm free play in it whilst the throttle plate is at idle position, and it's connected to hole number 1.

Unless its chronically low, I'd have thought small differences in the fluid level wouldn't have caused it to slip in and out of gear. Sounds like all that crap inside was what was providing drive:D. Now that its been removed the forward clutch is probably metal on metal and slipping to buggery.

Well if yours has free play then yours is not adjusted correctly :o

It has to be under tension, no question as it will cause damage to the box eventually due to low line pressure.

If you dont believe me, look in your RAVE, or any service manual or ask JC or any of the other LR mechs.

130k doesnt mean it will be any good, there are dozens of reasons why the trans may have failed early, No servicing, heavy towing, high temps, oil contamination lack of line pressure etc etc.

I would get a professional opinion on it before pulling the box as it may be a valve body or govner issue which can be sorted with it in.

I have seen second hand ones for as low as $600 on Ebay but there is no guarentee of their quality and anything up to about $3000 for a change over from A&B which is basically a new trans in the old case fully tested and guarenteed or anything in between to have a normal auto shop do it or more than $3k for a moded up one with 3rd lock up, 4hp24 mods for added strength, sprag mods so you dont chew out a sprag and the list goes on.

It needs to be running so that all the nessesary componants are full of oil such as the Torque converter and pump, clutch servos etc etc and still have an adaquate amount of oil in reserve for flushing and cooling.

You cant just mark a spot on the dipstick and check when cold as some componants wont always drain down, it depends on what part of their cycle they are in when stopped (I think.....something along those lines).

If you can just wind up the idle to a nice steady 800Rpm or something like that and it should be nice and smooth, if it Idles lower than that then you probably want to bump it up anyway and if it's still a bit rough then there may be other issues.

Just thinking that if the pump relief valve was sticking open it might play havock with the level and the internal pressures in the box as it would grab prime and lose it again inconsistantly more at low revs.

Again though, it's a bit grabbing at straws, a pressure test would help a lot in diagnosing this problem.

Dont stress too much about the oil level being a bit high, better to have a bit too much than not enough.

The oil level (as long as you put as much or a bit more than what came out) should be fine and wont make any difference to how the trans changes so start looking at other possabilities and treat the fluctuating oil level as a symptom not so much a cause.

I would guess that the rubber O ring between the valve body and the filter has fallen to one side during installation and is not sealing properly. (The larger diameter one in the kit) This will give the same symptoms as low or no fluid, and will allow the fluid from the pump and converter to drain back to the sump after turning off, and will have to refill the converter etc before any drive happens again. Also, it will hop out of gear etc up hills as the pressure will be way too low with that sort of air leak. I would be dropping the sump and filter again and checking this O ring. If you continue driving it like this it will strip more clutch material off the packs due to low pressures.
I re read the posts and also noticed you said you had very little difference in oil level when engine was on or off. This is almost certainly due to that O ring leaking.

As someone who has a buggered auto, my amateur prognosis based on what you've written and the advice I've received from experts (after they've pressure tested the box and investigated contaminants in the oil) is you may be up for some large biccies.

I have a 98 tdi Disco auto. It has a touch under 140,000 k's on it, the engine is sweet, but the gearbox has always run a bit hot. 6 months ago, I replaced the standard auto cooler with a much larger one from a P38A range rover. This seemed to sort the overheating issues out, but three weeks ago the gearbox started slipping like crazy and wouldn't change out of 1st until I got the revs waaayyyyy high (regardless of cold or hot) and the oil smelt like it had served time in a blast furnace (didn't smell good at all). I now know the damage was well and truly done (most likely by the previous owner, who used to do a lot of towing of horse floats).

Solution in my case is replacing the existing auto with a fully reconditioned exchange unit from A&B Automotive in Dandenong (with a 3rd gear lockup conversion, apparently much better for towing). It arrives tomorrow and my local Landie experts get to change them over on Tuesday. I haven't been able to get anywhere near my wallet for some time as it is still smoking hot ........ :eek::eek:. I'm hoping to get out of it without going over about $3600.

I hope you get yours sorted out, but it's sounding kind of familiar........ sorry :(:(.

I would guess that the rubber O ring between the valve body and the filter has fallen to one side during installation and is not sealing properly. (The larger diameter one in the kit) This will give the same symptoms as low or no fluid, and will allow the fluid from the pump and converter to drain back to the sump after turning off, and will have to refill the converter etc before any drive happens again. Also, it will hop out of gear etc up hills as the pressure will be way too low with that sort of air leak. I would be dropping the sump and filter again and checking this O ring. If you continue driving it like this it will strip more clutch material off the packs due to low pressures.
I re read the posts and also noticed you said you had very little difference in oil level when engine was on or off. This is almost certainly due to that O ring leaking.

JC


So thats what happens if you dont fit that o ring properly :D

That makes sense JC :D

As someone who has a buggered auto, my amateur prognosis based on what you've written and the advice I've received from experts (after they've pressure tested the box and investigated contaminants in the oil) is you may be up for some large biccies.

I have a 98 tdi Disco auto. It has a touch under 140,000 k's on it, the engine is sweet, but the gearbox has always run a bit hot. 6 months ago, I replaced the standard auto cooler with a much larger one from a P38A range rover. This seemed to sort the overheating issues out, but three weeks ago the gearbox started slipping like crazy and wouldn't change out of 1st until I got the revs waaayyyyy high (regardless of cold or hot) and the oil smelt like it had served time in a blast furnace (didn't smell good at all). I now know the damage was well and truly done (most likely by the previous owner, who used to do a lot of towing of horse floats).

Solution in my case is replacing the existing auto with a fully reconditioned exchange unit from A&B Automotive in Dandenong (with a 3rd gear lockup conversion, apparently much better for towing). It arrives tomorrow and my local Landie experts get to change them over on Tuesday. I haven't been able to get anywhere near my wallet for some time as it is still smoking hot ........ :eek::eek:. I'm hoping to get out of it without going over about $3600.

I hope you get yours sorted out, but it's sounding kind of familiar........ sorry :(:(.

There you go, you might be able to get out of it worst case scenareo about $3600

Well if yours has free play then yours is not adjusted correctly :o

It has to be under tension, no question as it will cause damage to the box eventually due to low line pressure.

If you dont believe me, look in your RAVE, or any service manual or ask JC or any of the other LR mechs.



I'm not doubting you mate, it's just that there is a few mm play at idle.

The box has been out recently and it has been properly set up by a main dealer prior to sale to me, it shifts at the right road speeds and kicks down when needed so I'm going to be worried about it.

RAVE seems to detail only the V8s so its not much use.

If it blows up, A&B get a rebuild job and I'll sue the repairer for the cost for not setting it proper:D:D

Goldey please let me know how the 3 rd gear lockup works on a 300Tdi when done.

It'll be OK if you only drove a short while, but you may notice some clutch material in the sump already:(
I bet you're upset at yourself now for driving it like you stole it:twisted::twisted:

Glad its a simple fix though:):) unfortunately (or fortunately?) I've seen this sort of thing before...

done prob 20ks hope i havent done damage i cant slap myself enough just went outside and there it was sitting on the ground where i put the botttom one on and rushed and missed the top one gosh cant believe im that stoopid

Your trans, your problem, Ive told you how it should be, it isnt very clear in the RAVE CD ,I just had a look but it is the same on both V8 and Diesel as the trans is pretty much the same.

The Rave take into account a new cable and obviously doesnt take into account worn holes or pins.

It was Mal at Mornington Prestige (Ex Deacon automotive) who showed me how to set the kick down cable properly and explained to me why it is so important.

Dont trust any car yard to do a propper job, they will only do enough to get the car out of the workshop and thats about it, they will fix it if it stuffs up but I doubt you will get an A&B reco out of them as they will only take the lowest possible cost to them and legally thats all they have to do and no matter how good with the legal clap trap you cant make them pay more than they need to to get your car out of their workshop.

I suggest you take it to a decent LR specilist who knows how these things should be set up for a second opinion before you just resign yourself to it being good enough as from what your saying, it doesnt sound right and to fix it properly will cost a penny and if they dont do it properly it will cost you down the track anyway.

Im not trying to harp on but there is no reason to leave such a simple adjustment that can do so much damage due to ignorance or the fact that you are prepared to sue the people who sold it to you if it stuffs up.

By the way, depending on how you drive (the load) depends on how long it will last with a loose KD cable so it may last until just out of warrenty and then it's your $3600 no matter what you do.:(

JC just contacted me out of the blue and explained the set up. Seems I was slightly mistaken but it's all good now.

Which is good as I'm going on a trip in the morning:D

The kickdown cable is the one from the injector pump down to the trans on the LH side. The one you are talking about sounds like the shifter cable. It has a threaded rod at the gearbox end?

The shifter cable is fine like that, the kickdown cable up at the injection pump should have a bit of freeplay etc.

Something a bit sticky there I would think, there is a fair bit of fault finding on the RAVE Cd, give it a squiz.

Sorry Damo, just looked back at this post again,

The kickdown cable on the Tdi (and the V8 for that matter) will have a bit of slack against spring pressure that is exerted from the return spring down in the box connected to the 'cam' assembly, which actuates the actual shift pressure valve when the cable is moved. The rate in which this valve is moved is determined by the cam profile,(Different profiles even between V8 and diesel, model years, bla bla )and the adjustment available on the injector pump throttle lever (those 4 holes) The overall cable length adjustment is easier to determine by depressing the pedal to the floor and just off the floor a resistance should be felt, like a detent. This is the full 'dump' for downshift. The rate of pressure rise can be adjusted by trying the different holes out, but basically driveability is the best way to adjust these without a gauge. Gearchanges should be clean and at a reasonable revs, throttle position and road speed. I sometimes need about 30 minutes of driving and adjusting to setup a ZF after fitting a new downshift cable.

Just read this thread, and am hoping someone might be able to answer a few related questions?

When people say it doesn't change when cold and other have to rev it way high?
Does that mean it won't change to 2nd at all when cold?
Way high revs, is that 4000rpm or what?

I'm new to this D1 300Tdi auto, so what are the usual gear changes, revs etc?
Mine seems to have 2 "modes": normal acceleration always changes at 3000rpm, especially when cold. Very slight acceleration, changes maybe 2000rpm? It always kicks back to 1st when rounding 90 degree corners and accelerating back up, is that normal?
Also forgot to add that 1st to 2nd, especially when cold, is quite a harsh shift at 3000rpm under normal acceleration. Calms down a bit when warm.
If accelerating harder the change from 1 to 2 is much less harsh.

Jeep boy: when you changed the filter and oil, did you remove the left side transfer box mount as JC said to get to the back left nut on the pan? Did you use a jack to hold the transfer box in place once the left side mount was removed? It doesn't appear that you have to lift the box at all, just undo and remove the mount, is that right?
