guys i need your advice. yesterday, me and my family went up to my in-laws at tagaytay. somewhere along the way, i felt my vehicle having this vibrations as i was going 100kph. i have driven my vehicle at this speed before even reaching up till 120kph and no vibrations have occured. this is the first time i have felt it in my vehicle. even my wife made the same comment. another thing that we noticed is that when i change my gear to 3rd or 4th gear, parang "kumakadyot" sya. i didn't change my driving habit when changing gears. pero kapag change from 1st to 2nd and 4th to 5th wala naman. i know the fact that nangyayari ito kapag mababa pa yung speed tapos nagchange gear ka na e ganun yung feeling. usually i change to 3rd gear at 25kph and to 4th gear at 45kph or before my rpm reaches 2000rpm. any advice po? btw, thanks for reading, medyo mahaba po i know. i just want all readers to understand what the situation is para mas clear. guys advice po please. nga po pala, i'm driving a mitsu adv ss 02, i just changed my oil recently. thanks in advance.
