I installed the transmission this week and i am still missing first gear. Does anyone have any theories about what the cause could be? Everything works great in the transmission with the exception of 1st gear.

thanks,

My 92 300d had the same problem. I consulted with the Mercedez Source website and he recommended trying Trans X ( additive), so I did. A couple months and a long trip later 1st gear came back. Oddly enough it was immediately after I disabled the EDS and changed the turbo waste gate actuator to a pressure operated one. It had to have been the Trans X loosening up a sticking valve in the valve body.
