I have a 1998 Honda Accord V6. I removed the batter and can see the TCC solenoid (the big one) on top but there's some metal and rubber valves/tubes blocking the way. They are screwed in. I removed a screw but its difficult to move and its metal. So what's are they and how do I remove them? Is it difficult for me to do so? Here's a photo...

I think the TCC solenoid is outlined in green. I'm trying to remove it to test it. The stuff marked in red (A, B, C, D) I think are blocking the TCC removal. I removed the bolt at D, but still can't seem to figure out how to move those valves/pipes blocking the way.
