I am hearing noises from my transmission should I change my transmission fluid

I have recently started noticing noise in low gears and little friction while shifting through low to high. As I recall, the fluid has not been changed before. Should I go for a transmission fluid flush as I am afraid it might do more damage or just let the fluid drain and replace some of it, or just leave it as it is?
As I have started noticing these noises recently, I am wondering if I can stop the transmission from getting any worse. I appreciate any help. Thanks in advance.
