1978 Mercedes Benz 240d slippage in a/t and oil in air clnr

A factory authorized repair manual, you can get those other European import store.

I did not see the rest of your message because it was posted in the wrong spot, regarding your manual you can pick up a manual at your local store or pick up the factory one probably on eBay or at the dealer, regarding your transmissions issues, and you check the transmission oil level? That transmission takes Dexron II oil, when was the last time you service the transmission? Tell me what color the oil is and tell me what it smells like? Does it smell burned? The oil in your air cleaner is caused by a malfunction in the PCV crankcase ventilation system.
