Our CRV gen 2.5 is having some unusual sound when running. Everytime i'm going to change gear, engine's rpm rev up of about addional 200-300 rpm (umuungol) that is not normal in any engine.
Eg. when i'm in 3rd gear going to 4th gear * 1900rpm when in the sequence of upgear it will went up upto 2100 rpm although i'm not stepping in the gas pedal.
