installed new brake light switch onA833

and changed out the gear oil - now I got some intermittent noise when clutch pedal is depressed that disappears when I let up on pedal a bit - what gives? - Sounds like it's dragging/ spinning maybe. This was not there before.
Used GL4 85-90 Stay -Lub. It might be lighter than what was in there before but I don't know for sure. Any ideas on what is happening appreciated. Can I at least rule out the new switch as a possibility? thanks
