SLIGHT HUM FROM INGINE WHEN HITTING SPEEDS 45-50

How does it affect the performance?

Hi it doest affect the perfomance of the car at all it sound like a squicky door opening if i let off the gas it go away and if i hit the gas again it come back, can really noticer it comming up hill 45/50

Is the clutch slipping or anything like that? Have you checked to see if there is a vacuum hose leaking that can cause a noise? Has the check engine light come on?

it an automatic and manual button on the under stairing wheel cluch not slipping , would a vac-hole leak bother the performance? there not inglite eather self check ok too

Based on where the leak is located, it could affect performance. Is there anything that changes the noise once you reach that speed? For example, if you turn will the noise change?

there no change on turns , but if i let off the gas it seem too go away and when iexcelrate it come back , it sounds like a door opening up and closing , starts at 40 when excelrating as soon as you take your food off the gas it goes away, i want too say it like opening a nd closing a fence, type of noise i really can notice it going up a hillim sure it happens on the flats too but not as loud thanks for the help too lenny
