C5 4HP20

In the first place I wouldn't go near the box with a pressure washer. There are reports on the forum of water entering through breather ports and ruining the boxes.

I'd also be very wary of the XLD FE - Specification (translated)).

It looks as though LT 71141 is available in Serbia, if I haven't got it completely wrong Mobil Delvac (also translated)

Then I remembered you are in Montenegro that doesn't seem to offer the same options.

There are quite a number of eBay listings that could be worth exploring.

UK based opie oils http://www.opieoils.co.uk also specifically list shipping to Montenegro, although shipping for 8Kg is about £66. Still might be cheaper than a 20 litre drum bought locally when you only need about 8-9 litres to fill a box.

Is it possibile to remove old oil from TC?

With great difficulty I once tried draining one by pacing it neck-down and left it dripping like that for days and days. Still there was a fair amount of oil left in it.

So in reality, no, you can't, Not completely.

I shall be interested to see the result of taking the old gearbox apart...

How much oil would you recommend buying to refill an overhauled box and still have a bit left over Jim ? 8 litres ?

Nine to be on the safe side Simon. 8 is a bit marginal as the stated capacity of a dry 'box and TC is 8.8 litres.

Pre-fill them too. It's so much easier to fill them through the speedo drive than it is through the breather hole!

with all respect to the above.
We had a similair problem here with the C5 of my son with the same aut gearbox.
After some meters the car stopped, engine still running but no movement.
Guess what, ........ there was not enough OIL in the gearbox and we filled it up with the procedure known from Citroen and voila, all ok and the car is still running as before. Means check oil first inside the gearbox before doing anything and don't go in panic.

Gosh You were lucky Peter. Normally if a 4HP20 runs that low on oil it kills it, or at least kills its bearings...

[Mandrake]

And the question must be - why did it run so low on oil in the first place ?

They don't use any oil unless there is a leak somewhere like the banjo joint, and a leak won't fix itself...

[Peterdb]

right, well we did found out that the control prop under the gearbox was leaking, he (my son) never told me that there was some oil on the road sometimes!!! But if the part (converter) between the engine and gearbox doesn't have sufficient oil to move the gearbox components it will run a little and then when it has put the oil into the gearbox for further action but don't have enough oil to "play" with the effect is there, no running car!!
Also overnight with no running engine the oil will come " in rest" so called and will fill this part (converter) but not sufficient.
After this event happen my son did until now drive 35000 km so call it lucky that no further damage happened that time.
What I'm asking myself is : how much oil came out of this gearbox what was dismantled now? I suppose he drained the oil from it before opening the box.
The total of oil inside is ca 4 ltr min as I remember it well.
Sorry if my english is not correct but being a Dutchman, the english is not my mother language.

[CitroJim]

No worries about your English peter, it is fine Much better than our Dutch that's for sure

So the gearbox was not totally empty then, just very low... That does help to explain it and that it would drive when cold after a rest and then stop makes perfect sense.

I am aware of a 4HP20 that developed a leak on the Banjo unions that seal the external pipe from the top to the side of the gearbox. It is high-pressure oil here the leak was enough to empty the box in about 200Km and kill it.

missed off that there was a 3rd page
One of the companies that quite a few people on this site use, ship to pretty much anywhere:
http://www.opieoils.co.uk/t-carriage.aspx#International" onclick="window.open(this.href);return false;
And here is the ATF: http://www.opieoils.co.uk/p-69401-mobil ... fluid.aspx" onclick="window.open(this.href);return false;

If you can wait a while opie do 15% off deals around the end/beginning of each month, or you can try leaving the site on the "register" screen, and it'll offer you 15% off if you leave them some feedback.

It might be expensive to ship, but if rates over there are anything like here in Sweden, it's cheaper to get it delivered from the UK than to buy it locally.


It might be worth popping these guys a message too: https://oeldepot24.de/lieferung/" onclick="window.open(this.href);return false; they might be able to ship to you too. They do the 20l barrels (they have 1 in stock currently).

Gearbox is inside car. Connected on Lexia. Do I need to pair something in ECU, serial or similar?

No, you just need to reinitialise the auto-adaptives from the Lexia After-Sales menu. The option is not available in the Diagnostics menu...

[Mandrake]

Was just trying to post that Jim when my browser crashed and lost my post so you beat me to it...

The auto adaptive reset is actually in the "Replacement Parts" section on the Lexia. After doing that the car needs to be taken for a moderately brisk test drive for about 10 minutes where all the gears are used and the gears are changed frequently.

[CitroJim]

Yes, I thought when I was posting it that After-Sales wasn't quite right Simon so thanks for making it right

Main thing is you won't find it in Diagnostics...
