2008 Ford Fusion SE fnr5 transmission
 

I have trouble with the tranny, starts in first jumps to 3rd and that its. Also, will lose reverse sometimes when hot. Flushed and replaced the oil and filter. Some help a bit smoother but same problem. Getting P0757 code solenoid B stuck open. Removed the valve body and now on the bench. When I test Solenoid B with a 9V battery, the relay clicks ok but the shaft in the solenoid does not move, should it, should I see movement, I would think it should go back and forth with the clicking sound, the OHMs are 2.8. But when I check solenoid A it's the same, I am confused. That is my question should the solenoid shaft move back and forth when applying 9v
