Couldn't really remember if i posted this on here.
Turns out I didn't..
The ZF box in the D2 really is a match made in heaven, compared to a 300tdi with the same box they're miles apart.
However mine had been shifting quite "hard" sort of shunting into gear instead of that smooth upchange you'd normally expect.
I for one know the Gearbox was last serviced in around 2009 when she had around 100k, so thats 84k without a service, and i have no idea what fluid they used.
So,
The sump is here.
I didn't really document the change with pictures, as ATF is not nice to have on ya camera!
I used Millers Millermatic fully syn
The fluid change procedure is relatively easy..
#1 Drain the old fluid
#2 Remove the sump
#3 re fit fliter
#4 new gasket and put the sump back on, do the bolts up snug.
#5 With the engine off, fill the sump until it trickles out,
#6 start the engine and select every gear and hold for 3 seconds in each
#7 slide back underneath the start filling again until it trickles out.
#8 re install the plug and repeat #6
#9 re check the level and you're done.
All in all you should get around 4.2 litres in and out..
For filling i prefer one of these.
The fluid wasn't too bad,
D2 on the left.
All in all with the new fluid it shifts so much better..
Which is nice/
