Last night was perfect weather and I did a bunch of stuff on my XKR. This was one of those jobs.

I bought:

-Duralast TF178 Transmission Filter $17 at Autozone (LINK)
-2x 4qt Valvoline MaxLife ATF $40 at Autozone (LINK)
-1 722.6 Dipstick, bought a long time ago but about $8 (LINK)

What tools:

-1/4 and 3/8 Drive Ratchets
--5mm Allen socket/key/whatever
--5mm Torx socket/key/whatever
-IR Thermometer (borrowed a Fluke 62 MAX IR Thermometer)

Steps:

Pelican Technical Article: Mercedes Benz - Automatic Transmission Fluid Change

This is a very easy job. This is so much easier than the ZF units I've worked on. The pan gasket is quite clever too; this is a very straightforward job.

 

You might have considered replacing the electrical coupler o rings, these will eventually leak on this transmission, one of only 3 problems we'll possibly see. You'd drain fluid, pull coupler and throw on 2 o rings.

 

My understanding is that only the coupler with included o rings is available now. Is there a source that sells just the o ring kit or separate o rings?
Thanks.

 

I believe you can get them through Mercedez
