Gearbox oil change process

[five50]

Does anyone have detailed / service manual instructions for this?

I assumed it would be a straightforward oil in and out job - however apparently some twin clutch boxes have more specific requirements including getting oil up to temp etc.

Any thoughts appreciated.

I don't remember where I copied this from (not my notes).

Gearbox oil is DW5 or FFL-7 (same thing, different codes). Buy 4 litres

Draining:

• Get the gearbox oil up to 40C+
• Remove the under tray (diffuser can stay on)
• Undo the drain plug on the gearbox with an 8mm hex socket
• Approx 3.5 litres of oil will drain out
• Re-fit the drain plug

To re-fill, you will need a length of clean hose pipe and a funnel

• The filler plug is a plastic wing nut thing about 10cm above the drain plug. Remove it
• Feed the hose down from the top and insert one end of the hose into the filler hole and fit a funnel to the other end
• Pour the oil in
• It will take about 3.5 litres (mine was a touch more) before it starts to come out of the fill hole
• Remove the hose and re-fit the plug

Thank you - much appreciated. For avoidance of doubt, did you do this and was it ok? Or notes for a possible future job?

Have asked a specialist garage if they can do it whilst the undertray is off for a different job - but they are wary in case they get it wrong given the possible consequences.

So trying to maximise certainty.

Also - point of order :
Always remove a fill plug first in case of problems then you can still use the vehicle before you empty the oil.

I had this problem when I drained the oil on my Defender TD5 transmission many years ago only to find I didn’t have the required torx fitting required at the time.

I've done it too and it's really simple, as Liam says above. Miserable's advice about removing the fill plug first is great advice too

Exactly this, we have done a few , including my own much simpler than made out.

Thank you for the response here. As above the independent specialist that I am planning to use does some work on Alpine's but has not done a gearbox oil change before and is wary.
It seems like Porsche twin clutch boxes have a very specific procedure, for example.
Can I ask as you say 'we have done a few' - do you do the changes on behalf of other people and any issues? Have you seen official service notes from Alpine?
Any thoughts much appreciated.

Good tip. Thanks. I'll try to remember that one.

Hi,
I run an independent sports and performance workshop in Worcs, mainly Porsche based but not exclusively Porsche, We have done 3 Alpine trans oil changes for customers, and did my own car earlier this week. All following official Procedure
It is much simpler than Porsche, for which you need PIWIS to carry out the procedure, the A110 is just like changing a manual gearbox, the on ly reason you get it to 40 degrees before draining is so the oil drains out more freely.

Many thanks - much appreciated.
Would ask about a booking but unfort am in London.
