I'm thinking that at around 70k miles, my '09 2.0HDI auto would benefit from a gearbox fluid change. I've researched the fluid type and settled on Carlube's ATV-LV as meeting the correct spec. I know that a full fluid change isn't the simplest of things to do, so thought about doing it 3 litres or so at a time.

 

Is it as simple as removing a drain plug, measuring what comes out and replacing that with the same amount of new fluid? Are the drain/fill plugs easy to find?

Which gear box is it - AL4 or AM6 or AT6 ? The following is from the service box procedures. Previously coastline taxis has recommended to use a dealer for auto box oil changes so something to consider, it should take about 1 hour. If doing it diy, if you are not sure about getting the right oil use a dealer and you may also find if they do the oil change they will buy the oil in bulk so it might part offset the labour charge. It looks as if you need to be able to read the oil temperature using a diagnostic tool.

 

This is the procedure for the AM6:

2. Drain and refill
CAUTION : The gearbox must be drained when the oil is hot (60 °C minimum), to eliminate the impurities suspended in the oil.
N.B. : The oil change is partial, since the converter cannot be totally drained.
 
Put the vehicle on a hoist.
Remove :
  • The protective panel under the engine
  • The top-up plug (2) ; Using a TORX socket wrench (this plug looks to be under the gear box and is the plug in the centre of plug 1 next removed)
  • The oil overflow and drainage plug (1) ; Using a 6 -sided wrench
N.B. : Approximately 3 litres of oil should flow out.
3. Refilling
Refit :
  • The oil overflow and drainage plug (1) (equipped with a new seal)
  • The top-up plug (2) ; Using a TORX socket wrench
 
 
Remove :
  • The air filter housing
  • The filler cap (3) - (looks to be on top of the gearbox)
Use tool [0340 - topping up cylinder].
CAUTION : Ignore the information mentioned on the tool [0340].
CAUTION : The oil type "AW-1" in AT6 and AM6 gearboxes with engine version Euro 5 is specific and cannot be replaced with oil type ""JWS 3309"".
Dry gearbox oil capacity : 7 litres (approx.).
Type of oil (Red) :
  • EURO 5 engine : AW-1 oil
  • EURO 4 engine : JWS 3309 ESSO oil
Volume of oil remaining after draining : 4 litres (approx.).
Quantity of oil to be replaced : 3 litres (approx.).
Refit the filler plug (3) (equipped with a new seal).
Initialise the used oil counter (follow the diagnostic tool procedure).
4. Check the oil level
Prior conditions :
  • Vehicle level
  • Check that the gearbox is not in downgrade mode
  • Remove the filler plug (3)
  • Add 0,5 additional litres of oil in the gearbox
  • Apply the brakes firmly and move the lever through the various selector positions
  • Gear lever in position "P"
  • Engine running at idle
  • Oil temperature 60°C (+ 8 ; - 2 °C) (measuring of parameters using a diagnostic tool)
Remove the oil level plug (2).
4.1. Stream of oil then reducing to a sequence of drips
Refit the oil level plug (2).
4.2. Sequence of drips or nothing
Refit the oil level plug (2).
Stop the engine.
Add 0,5 additional litres of oil in the gearbox.
Repeat the top-up procedure.
N.B. : The level of oil is correct when the stream of oil becomes drop by drop.
Refit the oil level plug (2) (equipped with a new seal).
4.3. Check the oil level (continued)
Refit :
  • The filler cap (3) (equipped with a new seal)
  • The air filter box
  • The protective panel under the engine
Too high a fluid level can cause :
  • Overheating of the fluid
  • Fluid leaks
Too low a level will lead to destruction of the gearbox.
----------------------------------------------
This is for the AL4 gearbox:
2. Drain and refill
CAUTION : The gearbox must be drained when the oil is hot (60 °C minimum), to eliminate the impurities suspended in the oil.
N.B. : The oil change is partial, since the converter cannot be totally drained.
Raise and support the vehicle on a 2 -post lift.
Remove the under engine protection .
 
 
Remove (from under the gearbox):
  • The spacer bar (3)
  • The oil level plug (2)
  • The oil overflow and drainage plug (1)
N.B. : Approximately 3 litres of oil should flow out.
3. Refilling
CAUTION : Adhere to the tightening torques.
 
 
Auto gearbox AL4
 Fit :
  • The oil overflow and drainage plug (1)
  • The top-up plug (2)
Remove : The air filter unit and its air inlet ducts.
 
(from on top of the gearbox)
Uncouple : The gear selection control cable (4)  Using a pair of thin-nosed pliers.
Release : The gear selection control cable (4).
Remove the filler plug (5).
Fill the gearbox ; Using tool [0341].
Dry gearbox oil capacity : 5,85 litres.
Oil remaining after draining : Approximately 3 litres.
Quantity of oil to be replaced : Approximately 3 litres.
Refit the filler plug (5) (equipped with a new seal).
Fit the cap (5).
Refit : The air filter unit and its air inlet ducts.
Initialise the used oil counter (follow the diagnostic tool procedure).
4. Check the oil level

  • Add 0,5 additional litres of oil in the gearbox
  • Apply the brakes firmly and move the lever through the various selector positions
  • Set the ger selector to parking position "P"
  • Engine running at idle speed
  • Oil temperature 60°C ; (+8°C/-2°C)
 
 
Remove the oil level plug (2).
Distance "A" : 48 mm (straight length of plug).
4.1. Stream of oil then reducing to a sequence of drips
Refit the oil level plug (2) (equipped with a new seal).
Fit the cap (2).
4.2. Sequence of drips or nothing

Thanks for the reply, and for the very detailed info, much appreciated! My car has the AM6 box I'm told. I take on board what you say about getting a dealer to do it - I think I'd be happier, albeit a bit lighter in the wallet! I've just spoken to Autoworld in Chesterfield, they've quoted £160 all in. I'm waiting for a well-established local autobox specialist to call me back, just to see what their price is like.

 

Thanks again,

 

Pete

I do not know what the oil costs but £160 seems a bit steep. I would be tempted to do what you first suggested and drain it and measure what you got out and then put the same volume in. Maybe wait and see if coastline taxis has something to add when he is back on the forum.

Join the citroen/peugeot trade club and then get a price from the dealer. puting the wrong or not enough oil in will cost you a fortune to put right.  with the dealers your covered if anythng goes wrong. We were paying around the £100 mark. But were lucky up here as we got a great citroen dealer (town center citroen). Alan in the parts is 1st class .  if your not to far away then book it in there and have half a day shopping in sunderland.

Thanks for the reply. I've managed to get a fair chunk off that price on a 'friends and family' basis as a friend works at the dealership - that should bring it down to around £125. The autobox specialist hasn't got back to me yet.

 

Sunderland's a 260-mile round trip unfortunately, but thanks for the suggestion.
