    Noise if 1st gear after smf conversion kit

    Guest-only advertisement. Register or Log In now!
    Hello I just bought an 2004 audi a4 ultrasport 6 speed and there is a rattling noise in first gear. But in any other gear there is no noise. Also the clutch has just recently been changed they replaced the dmf for a smf conversion kit from valeo. The new clutch feels fine and shifts really good. I did some research and im not sure if it is the new clutch or the a chipped first gear is making the noise. I read that the smf can make some noise but mostly in netural. I also read that a chipped first gear could also make some noise in first and it is quite common for these cars. Im not sure if i need a used transmission and have them reuse the conversion kit or should I just replace the flywheel and clutch with a dmf. please help.

    Does it make the noise as long as you are in first gear during acceleration? If so, you have a chipped 1st gear.

    A lightweight SMF can cause chatter at idle and when accelerating at very low RPM's (below 2,000). After that it goes away. The Valeo kit is not a lightweight SMF. It weighs close to the same as the OEM flywheel.

    I have been running the Valeo kit for several years and over 60K miles. No chatter whatsoever.

    Is it like a deep metal rattle or a lighter sound? And does it sound like it's from the tranny tunnel or can't you tell?

    It's a medium rattling sound that gets louder as the rpm gets higher.

    My experience with my Valeo SMF conversion is the same as OG and in fact I chose it because of his recommendation. You may have a damaged 1st gear.
    It's mind over matter. But if you don't have a mind, it really doesn't matter.
