weird sound sa primera at segunda.,help please

[Raff Gutierrez]

help please.,napansin ko lang kasi na whenever nakaprimera or segunda (after realeasing gas pedal) na parang may tunog na yung gulong parang nasa road na maraming bato.,parang coming from the wheels.,pero kapag nasa tersera and up naman ako wala naman siya.,is this normal dahil naka muffler ako or something is wrong with my 1st and 2nd gear.,?so far other than that may kabig ako ng konti sa kanan wala nothing unusual naman na.,newly tuned up naman yung engine and ive asked servitek kung may problem or wala pero so far naman wala daw,though hindi ko natanong ito.,thank you sa mga sasagot.,sentra gx 06 po yung sasakyan.,

[phezthie]

how about your engine support, have you checked it?

[nebular]

ok naman po engine support. pag neutral wala nginig kahit irev-up ang engine at kahit naka on AC.
