Xantia auto gearbox problem

[i5xp]

Hi all
I have a Citroen xantia 1.8 16v 1999 with the al4 auto gearbox with snow sport mode buttons
I was about to drive after stopping for 30 minutes but engine only revs doesn't move ,the snow and sport lights were flashing,i shifted to reverse and reverse works i can go backwards but not forwards, i tried 3rd gear 2nd gear 1st gear none worked.

First thing is to get a Lexia on it and see what it says. The snow and sport lights flashing indicate there is a fault stored in the ECU. Only Lexia diagnostics to read the fault(s) stored.

That it reverses but does not go forward suggests either an electrovalve problem, valve block problem or a broken brake band..

Hopefully the former as that can be fixed without removing the 'box from the car.

I put 1 liter of castrol def3 atf oil in. I also noticed that when i rev to 3000 rpms and realase gas pedal the cars moves for for a split second then stops. I could drive 15 meters like this. I also want to know if theres any difference what atf fluid to use and what to use also wheres the gearbox fluid filter located. In my country theres nobody who has the lexia scanner and probably only way to get a lexia is to buy one off ebay.

That is most definitely the WRONG gearbox oil. The only stuff to use is Mobil LT71141, as anything else will cause problems. Wait until CitroJim or addo see this post, as they are the most knowledgeable on them.

EDIT; Just spotted that CitroJim has already started answering.

As you say James and a point I was going to make...

Sadly, I doubt a fluid change is going to fix the issues the 'box is suffering from unless there is hardly any ATF in the 'box to start with...

You must look to get a diagnostic session in the first instance.. Many members on here offer the service so there should be no need to buy a Lexia Kit...

Sorry Jim, don't think we have any Lexia owners listed in Estonia
