I have noticed this weird sound for awhile now. I thought it was just wind sound from AC, but it's from engine. It's not from my CAI, I think it's coming from header. (I'm not sure about this). It didn't have any sound when Comptech header was installed when was about 5 months ago. Is leaking sound similar to wind sound? Does leaking decrease the power too?

 

if by wind you mean kind of a whine then there is a very very good chance its your transmission. i've replaced two of them in CLs that were makign wind/whine type of noise when driving /under load

 

DAMN...my cl makes a funny whining noise during driving under normal conditions....i hope i dont need a new tranny. it goes away under heavy acceleration but its very noticable with the windows up and the radio off going reg city street speeds any suggestions?? btw sorry if i am jacking your thread just seems like i have similar problems. oh and i forgot to mention my car seems to be fine are there any other signs of a bad tranny that i should know about? sometimes when my car is really cold and i put it in reverse it jerks real hard

 

anyone know anything??? i know someones gotta know somethin...im all worried now. should i not be driving my car?

 

If you are hearing a whine, which varies depending on RPMs and happens during acceleration, then it's probably your transmission. A lot of people have had this issue.

I've had 2 transmissions replaced because of it...two. My third one has slowly started making the noise again as well. It's annoying as hell if I drive without the radio on. I have 53k on the car, so I am going to keep going in for new transmissions until the warranty on it expires at 100k... or until I get one that doesn't make that annoying whine.

 

cool thanks man...wanna know some shit...i got the jet kit installed about 6 months ago and i called my dealer and said hey my car has been makin this noise since before i got the jet kit installed did yall not notice that when yall put the kit in? and she said oh sir im showing in our system that we didnt test drive your car after the kit was installed. wtf is that shit...no test drive after taking apart the tranny?? im glad i dont live in houston anymore. hopefully the austin dealerships have some brains. putting in a call to the one on 35 north right outside of town if your coming from san antonio...anyone know any feedback on the dealership?

 

dont even come close to taking apart the transmission dude all it is is extar hose that shots ATF down the fill plug hole. it only cools 2nd gear and slightly extends tranny life by lubricating 2nd gear clutches and does not effect dirvability in any way . so there is no need to drive the car . its all in yoru head dude
