Thank you very much Doc...if anyone knows where I can get the transmission parts or knows of someone reliable in my area who will do the job without knocking my head off because I'm a "girl", please let me know....

My S420 was also running really hot, like over the 120 mark, the mechanic said it was the AT fan?? (which may need to be replaced) but after he took it off and replaced my filters,(air,transmission) it seemed to start turning...and today it hasent went over 90..(maybe because its cold out today)

***I really enjoy the forum..I've learned a lot just reading the various threads..and so far everyone seems to carry on disscussions in a mannerly way...well ok, enough chatter..(everyone had a story and I wanted to have one too.) .you guys are cool, talk soon!
