Mercedes CLS55 AMG W219, Replacing the 722.6 Gearbox Conductor Plate & Transmission Fluid Refresh

As part of the big preventative maintenance, I swapped out the conductor plate for the 5-speed 722.6 automatic torque converter gearbox (which is pretty much bulletproof) and also did a fluid refresh. Its almost impossible to get all the fluid out, that is done better with a flush (done with specialist equipment).

10 liters of LiquiMoly Top Tec 1800 ATF fluid
Febi Bilstein Transmission service kit (gasket, filter, bolts, drain plug, copper washer, connector)
New conductor plate
New conductor plate
Valve body & old conductor plate. See the black residue, time for some cleaning
More of that black residue…
New conductor plate fitted, cleaned the valve body as much as possible
Valvebody back in place, new filter mounted

I replaced almost 6 liters, the rest remains in the system off course in the coolers and the rest of the transmission plumbing. Maybe somewhere next year do this again, but also replace all/some solenoids and go to a transmission specialist.

Pro tip: Transmission adaptation reset is mandatory! I used method 2 of the video below




Mercedes CLS55 AMG W219, My First Oil Change With LiquiMoly 5W40 High Tech

Performed the first oil change on the CLS55 with LiquiMoly High Tech Low Resistance 5W40 oil. Bought 2x 5 Liter canisters, as the big 5.4 Liter takes about 8.5 Liters of oil in total. Also added in 1.5 canister of LiquiMoly Ceratec, a well known working friction modifier.

List:

  • 2x 5 Liter LiquiMoly High Tec Low Resistance 5W40
  • 1x Mann Oil Filter HU718/5X
  • 2x Mercedes Oil Sump Plug A3529970032
  • 1x Katsu Oil Filter Wrench Set

This was my setup for the day, used 2 ramp, which has enough ground clearance.

This is how the oil filter looked. It was in a bad state, seems the previous owner skimped out on maintenance…The rubber O-rings especially were very old and worn.

The M113k engine has 2 sumps, a front scavenging sump and in the back the main sump. I saw a lot of oil leakage, most of it was due to the rocker covers as far as I could judge for now.

Putting the Katsu oil filter wrench to good use. I used a combination of a vacuumpump with the drain plugs to get most of the old oil out

Performed some other things “while I was in there”, but I will describe that in separate posts.




Mercedes CLS55 AMG W219, Replacing The Rear Differential Oil

1.5 Liter of 75W140 GL5 Differential oil (LiquiMoly) and 2x new filler caps for the rear differential. I didnt have the correct hex key, but a T70 torx also works. Will be doing this again in the near future, so all the old oil is replaced with new oil.

I used a big syringe (150ml), which actually worked out very well. I will always recommend using new plugs whenever you notice that the plugs look old.

Mercedes CLS55 AMG W219, LiquiMoly Injector Cleaner

As part of regular maintenance, bought some LiqiuMoly injection cleaner. Will probably be using this every now and then as preventative maintenance.
