DON'T FORGET TO REPLACE PILOT BUSHING.

Why should the pilot bushing be replaced if it was not leaking?

I think youtube has a method where owner stick rubber hose into the filter hole, dip it in gallon container of new ATF, put big drip pan under open transmission and run the engine for few seconds to naturally flush the internal parts.

Thanks for mentioning this video, I cycled through a few until I found it. Here is the link with the time of your exact point.

Got ya. I thought the leak would be visible without taking it out. And at $10, it is worth it.
Thanks!

What part are you referring to here? Can you post a link?

Best flush video I've found.

I also found this video which is not specific to Benz but has useful information.

For those looking in Alberta and Saskatchewan, and maybe BC, UFA Petroleum has Shell ATF 134 for $6.67 cad a quart.

I am about to do a complete transmission fluid flush and I have seen on other threads members talking about using 236.10 in old transmissions (mine has 220K Km) instead of the 236.14. Could someone confirm that this is better suited for old transmissions than the new upgraded ATF 236.14 despite the fact that MB claims 236.14 is backward compatible?
