Hard to shift from one gear to another on manual transmission. on 2006 Chevrolet Cobalt

Even though it only has 53,000 miles. the transmission is getting difficult to shift from one gear to another. There is no shuddering or any other of the usual symptoms of a bad clutch. It is continuous and no matter what the temperature. I can drive it, but it is causing me concern. Is there something that needs to be lubricated?

maybe you have an issue with the hydraulic clutch circuit.
Thanks for your response. I'll look on Angie's list to see if I can find a trustworthy mechanic there.
