Post this question on the Eddycat's Garage section, Eddy will know.
I am not sure what the solenoids do individually. There appears to be 5 of them, solenoids A,B and C, and 1 and 2.
I think the Technical Service Bulletins refer to them as valve bodies. There may be good news, I think these can be serviced without stripping the tranny off the car.
Ask Eddy, he will know.
