I did some searching and haven't been able to come up with an answer to this. Does anyone know what size deep socket or wrench is needed to remove to the CAGS solenoid?

I'm going to install my RPM T56 Transmission this weekend and that's the last item I need to move over from my old transmission. Any help would be greatly appreciated

 

Well in case anyone searches for and finds this in the future, I ended up just using a large (1.5" max opening) adjustable wrench and it came right out.
