Tranny Plug Socket?

[Bob Reinhardt]

Hey all,

I'm trying to replace the tranny fluid (going to RedLine) in my 1991 
200q20v but I'm having a bear of a time trying to get the fill plug 
out.  I've got a 17mm hex wrench but I just can't get the leverage I 
need.  Does anyone have a 17mm hex head socket that I could 
borrow/rent?  I'm wondering if that might do the trick.  Other advice 
on this operation would be much appreciated.  Many thanks!

Cheers,
