My first post here! I never thought i woud join this site, bu i brokedown (soon after my car did) today and signd up. I have a 1992 300SE and the tranny went on her today. I brought it to an AAMCO transmission service station and they gave me a price of $2100 to rebuild,plus a free warranty to cover it! Mercedes wanted $6000 for a new one, minus a warranty! Anyone have similiar trans probems with thir 140 4-speeds? I love the cr to death. She has a well maintained 123,000 miles on her. I plan to keep her for well over 200k. I'd like to get in touch with other w140 300SE owners to compare notes.
