Thank you beinet1 for this "how to", and CLF for re-posting as PDF with pictures.
Well, I thought I'd give it a go, seeing as the ATF in my tourer was changed by previous owner, 45k ago, at 30k miles.
I didn't previously have any problems with gearbox as such, but just thought I should do the change, as father in law was going to do his, and wanted to watch a guinea pig first.😨

Out of curiosity, I 1st checked the fluid level, before draining anything, and approx 200ml came out.
It looked like this:😱

That made up my mind to follow beinet1's procedure, (almost) to change as much as possible, rather than the "normal" drain procedure.
I didn't take temperature measurements at any stage, but done all drain/ level checks, within 20 mins of taking out for a run, and getting up to "normal" temperature, say 84C.

I used this, purchased from rimmers...
.
OK, we probably all know what it looks like, but for comparison with photo 1, it looks like this:


Fluid amounts at various stages were as follows:
Level plug overflow: 200ml

Drain: 3050ml
Fluid in: 3500ml
Fluid outvia cooler). 3050ml (till it stopped pumping).
Spillages, 😱: 600ml,
yes, there were some😬, mostly caught (500ml) but made allowance for 100ml escapees.
Fluid in: 3400ml

So excluding initial overflow from level plug, that was
OUT: 6700ml
IN: 6900ml

At that point, there was no sign of anything coming out of the level plug, so added another 100ml, and then about 50 ml came out.

Hardest bits:
- separating the collar on the oil cooler
- having to rig up a variety of hoses and tun-dishes
- having the patience to fill the thing... it took an age.😤

Having only driven the 15mile home from FIL house, the only difference I can note is that it doesn't change down a gear, as readily as before.
Nothing major, just different, but then again, it was fine before the change. 🤔

So, my only query to put out there.......
What do you make of the colour of the fluid that came out, seeing as it has only down Approx 45k.?

Previous owner was a gentleman, so I've no reason to assume it wasn't changed, or that correct spec fluid wasn't used.
(He had posted a bit about using N402 spec, back in the day.)
