How to check (or replace) the trans fluid for 2009 ML550?
I am new with this forum. Hope everything is good with you.
A quick question. I have about 155k miles on the truck. I believe it's time to check or change transmission fluid for her. But there is no dip stick and no idea how to check or change.
Thanks in advance.

Change fluid and filter every 40k miles.
Fluid is added via same hole as drain hole. Therefore it is pumped in, and special tools are required. Amount to add is related to temperature. Vehicle must be level.
Oil pan is held on by aluminum bolts that are one time use only. They stretch.
