Cisco 3750 (WS-C3750-TS) Switch. If we configure as 100MB/Full duplex, we are getting packet loss. If we configured as autonego it is working without any issues.

IOS: c3750-ipbasek9-mz.122-25.SEC2.bin

Can anybody help on this.

There are a few bugs with the port settings on 3750s - one where you can configure and all is OK, but on reload they fall back to auto, plus a couple of others.

I am pretty sure that version of software has none of the bug fixes, but have not done a specific check. You need to either upgrade to the latest SW, or leave ports on auto.
