Its Diesel, i already ordered new modified filter, my only fear is to drain the whole oil and than add new is that i might destroy the transmission

Not that I have any need to but if I do or anyone else finds this what's the process on a D4? Whilst looking at how the headlights came out I noticed it's quite different down that side of the radiator so I guess it's in through the gearbox fill.

How much oil do u usually get out with the steps you are doing ?

To answer you question it depends if diesel or petrol.
The top hose is disconnected for ease.
Then the radiator end is the return to the gearbox on a diesel I think
The loose pipe expels the old oil when engine running.
We usually pressurise the new oil in with engine off.
I like to
1 pump the old oil out with engine running
2 Drain sump.
3 Wait overnight.
4 Drain sump again
Not really worth changing the filters on these. Only benefit is that it allows you to change the electrical connector sleeve seals, which will leak at some point!

Yeah. It’s a change. But also changing what is in the torque converter.
I would just do a change. Then drive for 6-12 months and change again.

Have you looked at Filo's post for DIY flushing ? its about as simple as you can get, use the outlet hose and that goes into the radiator and put a 1m length of hose on the radiator barb to fill the trans.
Dilute the dr tranny with atf and add it thru the radiator .

Yes its pretty clear but im having issues to figure out where does the blue hose goes . The black clearly into the radiator but the blue ? Does it go to the hose that i would disconnect from the radiator?

Yes, a hose onto the radiator barb and another onto the trans cooler hose using a short piece of copper tube or a brass joiner.

Drain, replace the sump, refill then continue on with the process.

When changing the sump do you guys add any sealant on the gasket of the new sump or no ? If so what is advisable to use?
