I was dazzled by the sun and bought a 91 500 sl, I should have worn a sun hat as the rays got to me.I've changed the spheres,got roof and electric problems and now I need some advice about the gearbox, It was running fine I had driven 20 miles,turned a fast 90 bend in my driveway,the gear then slipped, engine revved, no drive.The next day I toped up the box with 1 litre of atf I now have forward but no reverse. I've just dropped the sump and filter looks like very brown and some fine particles Ha Ha, can you recommend some one who will rebuild the gearbox, I am near Milton Keynes but I don't mind travelling to the right person. Any other advice will be welcomed. Thank you.
