Transmission Question (Reference Sensor)
 

I have replaced the engine in my "88 560SL. In mating the transmission back to the engine, does the "reference sensor" have to be in a certain position in reference to the flywheel? Does it have to be aligned with anything prior to my mating of the transmission with the engine? Does the flywheel band have to be aligned a certain way? Thanks

reinstalling transmission to new engine orientation?
 

no orientation is required. Any of the three possible positions will work fine.
