2015 Diesel ML350 4Matic transmission fluid change

Can anyone go through a 2015 diesel ML350 4MATIC (with air suspension) transmission fluid change please? Is it similar to the GLK350 GAS 4MATIC where you:
  • open the drain plug over a big drain pan (what, 10 litres size, I guess?)
  • use a screwdriver to knock over the overflow tube (messy)
  • drain
  • remove/inspect & clean pan
  • replace filter
  • drain torque converter (or not)
  • put it back together with new bolts
  • torque the bolts (spec pls?)
  • fill to overflow
  • start & change gears a few times to clear bubbles
  • heat up to operating temp
  • fill/dribble out until full
  • reinstall & torque drain plug (spec pls?)
Is it this simple?


Question: I wonder if I....
  • threaded in a flexible vinyl throwaway tube (just enough to hold it) after opening the drain plug
  • put screwdriver up the vinyl tube
  • butt the screwdriver up to the handle to seal the vinyl tube
  • knock over the overflow tube
  • quickly pull out the screwdriver
- if that would save splashing fluid all over the place when draining starts.


Btw, any info on lubing creaking door hinges? No looseness yet, but needs lube.

Maybe its just me but it seems like you are trying to make a simple task complicated. If you have any decent sized drain pan centred under the drain hole you won't lose anything when you knock that (incredibly silly) drain standpipe loose. Making it complicated with auxiliary drain hoses will make a mess almost for sure.

I use whatever weasel **** in a can happens to be on the shelf at the moment on door hinges but if I have dry lube I'll go for that first and probably some kind of silicon goop next.
