hello

as you're probably aware the air pump on these do have a tendency to fail so yes I'd agree its worth considering a new air pump, however check the pipework to and from it 1st as they can break / crack and disable the part that way

and yes if you have a rough / hard shift then a change of fluid is a good idea, I'd try this 1st before changing the solenoid too as often fresh fluid is enough
