I have decided to change the trans fluid (drain/fill/drive/drain/fill).

How does one remove the "dealer service" plastic plug on the fill tube?

What does one replace it with? I have not found a source for one.

I have used the search function and came up empty.

Thanks, I saw that red contraption on AutohausAz and wondered where it fit. It is $0.88 and the fluid is $15/qt.

You break the red tab and drive the rest of the locking pin thru. You can reuse the pin without the top tab.

Tranny only drain out 3 qt or so. That mean you have to change the fluid many time over to get the 8.5 qt out

There is a new MB ATF that is about $8. It is the MB ATF 3353. Its Pink.. Old ATF in your tranny had probably turned brown.

You can drain the torque converter on the car, along with the pan drain you will get about 8 of the total nine quarts out. Use the MB synthetic that is made for the car, it is expensive but worth it.

the newer models have no plug to drain the converter. the easiest way to get all new fluid in there is either use a tranny service machine or disconnect a line at the tranny and run the car and continue to topm off the fluid level untill fresh fluid comes out.

I cant give an exact date but the models you have (according to your) profile are beyond 2000 and therefore should not have the TC drain plug.
