PLEASE COULD SOME BODY HELP ME?

I HAVE A 2001 (51) VOLVO S80 2.4 SE AUTO,

PROBLEM ONE

WHEN I TURN THE STEERING THERE IS A LOUD NOISE COMING FROM THE POWER STEERING PUMP (I THINK), ALSO THE POWER STEERING FLUID IS FOAMING. IF I REPLACE THE PUMP WILL THE PROBLEM BE SORTED? I HAVE HAD SO MANY DIFFERENT ANSWERS FROM PEOPLE LIKE "IT COULD BE A LEAK IN THE PIPE" "IT COULD BE I PIN ***** HOLE IN THE PIPE" I HAVE CHECKED ALL THE PIPES AND FOUND NOTHING LIKE THAT.

PROBLEM TWO
EMMISION SERVICE REQUIRED - JUST HAD FULL VOLVO SERVICE!

PROBLEM THREE

AUTO GEARBOX GETTING LUMPY ON GEAR CHANGE - FLUID CHANGED 3000 MILES AGO.

 

The pump might be bad.

The emmissions light needs to have the codes checked.

The trans is most likely on its way out.
