I am aware (from my time on the forum) that the LT71141 oil seems to be the correct oil to use in some PSA gearboxes. Other oils that purport to be suitable tend not to be suitable. I cannot say more than that, as I have never had an automatic car.

However, CitroJim (who is a member on the forum but (for medical reasons) has 'gone quiet') wrote up a guide on rebuilding some gearboxes, including an automatic one. It could be worth taking a look at his website;

Problem is that here where i live in Austria, only oil that i get when i search for LT71141 is that LIQUI MOLY Top Tec ATF, 1200 Automatikgetriebeöl , but what bothers me is that in description it says BMW LT 71141
I ordered it as i need to doo oil change urgently in next 2 weeks so i hope i dont destroy my gearbox with it...

That certainly looks like the right stuff.
Used to be Esso but changed to Mobil a few years ago.
The Mobil stuff is definitely correct for the PSA boxes.

I'll delve into it later, unless anyone else has the details but basically measure the amount drained, usually 3L, and replace with exactly the same amount.
This has to be done with the oil at a specific temperature ~ 60℃ IIRC.

The change has to be recorded in the (gearbox ECU) with a Lexia.

Repeat after a couple of thousand miles, then again after another couple of thousand miles.
There is a total of 7L in there but only 3L approx can be drained, the remainder resides in the torque converter.

Here are a few threads dealing with it:
Some links no longer active. Unfortunately it seems that the links for the official procedure are to Jim's site, eastment.net and although some of it is accessible, that section seems to have gone.
Unfortunately Jim is currently not active on the forum but when he is I will point this out to him and see if it can be resurrected and possibly the procedure placed in out "How To" forum.
Do have a read of those threads as it highlights the many pitfalls that can be encountered.
Will continue to try and locate the correct procedure.

Found these which I hope will be helpful.
I realised that you haven't mentioned which gearbox you have and there may be different procedures depending on the specific one.

If you post your VIN then we may be able to determine which one you have, if you don't already know.

Ok, so a bit late here, but you have a BVA4 HP20 (AG). This guide may help you.

Capacity is 8 litres in total (from new), but only approximately 3 litres are removed when draining.

Note there is a checking procedure detailed first, then the Draining & Refill Procedure below that will refer back to the Checking Procedure!

Tooling

You will also need access to Peugeot Planet 2000 Diagnostic Tool / Diagbox.
HP20 Gearbox A.PNG
HP20 Gearbox B.PNG
  • [1] Filling assembly (-).0341.
  • [1A] topping up cylinder (-).0341-A.
  • [1B] 4HP20 adaptor without gauge (-).0341-B.
  • [3] Pliers (-).0170-Y.
ESSENTIAL: Use only ESSO LT 71141 fluid.

Checking Procedure:

Prior conditions:
  • Check absence of faults using the diagnostic equipment
  • Place the vehicle on a lift (Vehicle level)
  • Gear lever in position P (Without handbrake)
  • Major power consuming equipment disconnected
  • Connect the diagnostic equipment
  • Select the parameter measures function
  • Ensure, before starting this operation, that the oil temperature is below 55 degrees C, if it is not, allow the oil to cool
  • Depress the brake pedal
  • Start the engine (Idling speed), Take the gear lever though all the gear change positions, return to P
HP20 Gearbox C.PNG
Engine running: At a temperature of 55 ± 1 degrees C, open the oil level plug (3).

Wait for the temperature to reach 60 ± 1 degrees C.

1st possibility:
The oil flows: the level is correct.
  • Refit the oil level plug (3). (Tightening torque to 2.5 da.Nm)
2nd possibility:
The oil does not flow:
  • Refit the oil level plug (3)
  • Add 0.5 litre(s) of oil (Refer to chapter: Refilling)
  • Resume the checking procedure for the oil level
Refit the metal part of the breather (2) using a 18 mm diameter punch and a hammer.
Clip the plastic portion of the breather (2).

Drain & Refill Procedure

Prior conditions: Draining to be carried out when hot to eliminate impurities suspended in the oil.
Draining is partial because the converter cannot be drained completely.
On draining, approximately 3 litre(s) are removed.
HP20 Gearbox D.PNG
Drain plug (1).
Tighten the cap (1) to 4.5 daNm.

Refilling

ESSENTIAL: Use only ESSO LT 71141 fluid.

Place the vehicle on a lift.
Release: The air filter assembly.

ESSENTIAL: Leave the air temperature sensor connected.
HP20 Gearbox E.PNG
Remove: The breather assembly (2) (Using tool [3]).
Raise the vehicle.

HP20 Gearbox F.PNG
Remove the oil level plug (3).
Using the tool [1], pour new oil through the breather hole, until it runs out of the oil level hole.

Start the engine: Idling speed.

Depress the brake pedal: Take the gear lever though all the gear change positions, return to P.
Add oil until it runs out of the oil level hole.
Close the oil level hole.
Stop the engine.
ESSENTIAL: Check the oil level (Refer to section above "Checking Procedure" ).

I found that same guide and went with it, only problem was that i was doing it on ramp so car was bit on angle, so i ended up pouring same amaunt that came out, gearbox already feels beter trought gears etc, kicking when switching from D to R is not so much as it was before....hmmm but i ended up now in doubts, i have next 2 big problems....Some idiot who was changing engine oil before i bought car, striped the oil bolt, so now i cant remove it to change oil, and second by my toughts HUGE problem that i figured out now, is that when i remove Oil cap from engie , it does not have vacum, instead it blows air out....what you guys say what im looking at, new car engine,,,etc...???
