Hi can anyone tell me how much A T F oil the auto takes.? I am going to change the filter .and drain the torque converter. So need to know how much ATF to buy

buy a 12 qt case from a shell oil distributor, it will be more than enough, takes about 8 during a change including draining the torque converter

The most important thing, of course, is to be very focused in setting the fluid level when you are are finished with the task. You will need a proper dipstick TOOL to do this (pictured below).

Also, unless you have a very early W208 (first model year, really), you will not find a drain plug on the torque converter (disappeared in MY 99). In most cases if you want to effect a complete change after dropping the pan and replacing the filter, you will have to then use the cooler lines to flush the rest of the system.

Good luck.

I have succesfully used a plastic stiff pipe to measure the fluid level, it is important to measure it hot.

For cooler flush I like the lubegard kleen it product in an aerosol can, In the newer MB they are actually plate n fin coolers in the radiator tank rather than the old simple copper tube like we saw in the old W123 etc cars

In most cars that I have used that flush quite an amount of debris also was washed out of the cooler.
