My 01 EX has been having trans problems since I got it. Now, it won't shift out of first gear. I got a check code of P0730, which is Shift Control System. I have done some searching on this code, and some people say to check the solenoids before replacing the transmission. They say there are 3 solenoids.

Can someone tell me where they all are?? I know where 2 of them are (1 in the front, and 1 next to it on the side), but where is the 3rd??? Thanks
