Quick one for you guys,
I am trying to identify the plug on the left side of this Automatic transmission, picked it up from someone who did a manual conversion a number of years ago so no chance of tracing the original plug / car.
It is for an M20 , going back into an E30 that was previously manual so no plug like it.
What is it, do I need it?

the car used to be a manual M20B25 which I stole for my coupe, ended up with this engine and this transmission.
