What kind of fluid should I use in the auto trans of a 1966 230 SL? After draining the pan and removing the cage for the bottom of the torque converter, how can I turn the engine over to expose the drain plug on the torque converter? Where would be a good parts source for this car, for a transmission filter for instance? Thanks for your help. Catch

 

Consider http://www.alldatadiy.com/ for maintenance information. Worth the annual fee.
Look at the German car parts ads as links for parts. I shop around a lot online for Benz parts, and usually order for over $50 each order and get the shipping free.
