I have a 2006 grand prix gxp and about a month ago, i get in my car and start it up only to here a weird humming/ almost a bad pump kind of sound coming from the drivers side wheel well. After i got in the car when it warmed up ( this was during the -25 degree weather we had... I get a traction control disabled light pop up on my DIC and also a service stability control light as well, followed by the check engine light. Immediately, from 1st to 2nd and then on it slammed into gear and shuttered a lot. Also it is doing like a rev clunk thing if i am i the highway and let off the gas for a few seconds and then give it gas again, almost like it needs to rev up to catch a gear or something and then when it finally does it lurches forward and then hops back in gear... I am so afraid that its my trans but here's the catch.. There is usually one or two days a week omw to work that the lights dont come on when i start the car up (outside temp seems to have nothing to do with its problem) the tc light and check engine light dont come on the the car shifts like its brand new. I just dont understand how one day it could feel like its been through hell and back and another it seems as if it was brand new. The guy at my oil place said the trans fluid is really burnt smelling a dark and i looked at it and it is in fact a darker color almost brownish pink. And it definitely smells burnt. But im pretty sure that this recent problem is what is causing it to smell like this and ruin the fluid. I have seem tons of forums saying that it could be a bad piece of a harness for a speed sensor on the wheel but that just doesn't make sense to me because it all deactivates when the car hasnt even driven anywhere yet and. I also have been having an issue lately where i have to push the shifter into reverse a couple times to get the key out of the ignition. And one time i parked the car, well i thought it was anyway, got out to throw something away, and i noticed that my reverse lights were on while the car was running. So I ran back inside to make sure it was in park and was like wtf.. lol IM SO CONFUSED AND IM SCARED HELP MEEE!!
