had mine done last nite
use dexron 2 ATF

sump plug on bottom of the auto box
take the autobox dipstick out
undo the sump plug and drain it into a container or jug with liquid amounts on the side so you know how much has come out
drain the box
when finished fit the sump plug again (with new washer!)
see how much fluid is in the jug and remember it(mine was 2 litres)
clean the jug and put the same amount of new fluid in as old what came out(2 litres in my case)
open bonnet and pour the new oil in the auto dipstick tube which is located on the left hand side of the head with a fine funnel
once the jug is empty refit the dipstick
start the car up go through the gears twice and recheck the level and thats it

do all this again 1 week later when the new oil mixed with old
so its even cleaner

Nicely explained Paul  

NB:  Some people managed to get upto 5 litres out, so ensure when doing the change that you have sufficient oil to replace it with ... don't get caught short

I was unfortunate enough to have to have my fluid changed, on my 93 2.5td, the directions (above) are incomplete.

The gearbox contains about 4.5 litres. there is about another 2.5 litres in the cooler and its lines, this too can be cleared out.

Disconnect the drivers side line to the cooler at the gearbox end (not the one with the switch in) and gently blow the atf back to the sump with an airline and allow it to drain as well.

This results in 80% of the oil being drained, I agree that it needs doing again shortly, but there are a lot less contaminents left in the system as only 20% of the bad atf was left in.
