Hi everyone got a question about the rpm. Usually, I will gently release the clutch, not really fast. When I do the daily drive, I always let my RPM stays around 3,000 then shift, But I noticed that only from first gear to second gear the car would be shaking, and the RPM is around 1,400. I know that means the gear and rpm are not matched. But when I do the same on second to third, my Jeep is chill. Did I do something wrong like I should release the clutch faster? Or this is not normal. Willing to listen to every advice, thank you all.
