[W126 Coupe] Oil leak - transmission advice

[stefansj at canisius.edu]

I only have slipping from 2nd to 3rd as well and only when cold. I'll try the flush 
first and maybe some Lucas? Jonathan, I trust your diagnosis but it doesn't 
bother me to the point of a rebuild YET lol. As for the oil, I'll change it out as 
soon as possible. After calling the dealership they told me 0w-40, didn't think 
they could lead me in the wrong direction! Thanks again everyone, Jas
