Hi guys, my clutch was replaced recently and now it's making a strange noise. It's only doing them in first and second gear when hitting around 4000 RPM and revving a little higher than usual. It was not like that prior to getting the replacement clutch put in. https://youtu.be/zp-DSQi4n5c It's a Toyota Corolla AE112R 2000 hatchback. What do you guys think it is? So I can tell the mechanic?
