    So the dealership informed me that the transmission was way overfilled with oil, to the point of leaking out the dip stick valve (I think he said there). They also commented on how the clutch felt "aftermarket". They replaced it, so whatever they put in. They adjusted the fluid and drove it around and said it sounded fine. "Nothing they haven't heard from every other manual car"

    What say you...


    EDIT: Just found this while researching what they said: "The amount of lubrication is also critical for shift timing. Overfilling a manual transmission will cause fluid to leave from the vent but will create windage problems. Windage is the effort needed for the gears to turn through the oil level. Dry sump race motors make more horsepower than a stock wet sump motor because the crankshaft is not fighting the oil in the bottom of the pan. Think of it as trying to run on a beach. It takes little effort to run on the hard packed sand near the tide line, but a great effort to run through 6 inches of water in the surf. When a manual trans is over filled and the driver makes a shift, the gear trains slows down very quickly when the clutch is depressed because of the fluid drag, altering the synchronizer timing and causing shift issues. A classic case of this was the Tremec 3650 series of 5 speed transmissions where the fill plug was actually designed too high in the case. On these units you cannot" fill to spill", but to Ĺ inch below the fill plug level for proper operation."

    Trying to do some research as to what it may be, this sounded pretty close:

    I'll suggest it to the dealership when I go back in on Monday :/

    How the hell do they keep giving it back to you when it's not fixed??? That's what I don't get.

    This is the first time they've given it back when it needs to go back for the same reason. Up until now, it's been one different thing after the next. They apparently never really heard the noise in the first place and when they drove it a while after fixing the fluid level, etc, they as well didn't hear it. I don't know how long "a while" is, but it was making the noise 15/20 minutes into my trip home.

    I will drive it back, it should be definitely making the noise by then and the tech will get in the car and I will drive around and point out the noise.
