hello to all first post here. recently swapped my transmission and put a new clutch, lightweight flywheel, throw out bearing and release bearing. i’m hearing a rattle from the transmission but unsure of what it is. used a different release bearing from the one that was in the clutch kit that i bought but not if it’s that that could be causing the noise. when engaging clutch noise goes away and returns when clutch is disengaged.E46 M3 tranny noise . any input would be appreciated.
If you rev the car to 900RPM, does the sound go away? If so, I'm almost certain that it is the lightweight flywheel causing the rattle. They are known for that.
It's normal if you are using a lightweight flywheel.
My car does the same.
I'm not aware of any solutions apart from raising the idle rpm.
Maybe some different oil ? But not sure how this could help...
the cheap clutch/flywheel kits are always out of balance and they make ALOT of noise. spend the extra $100 and get them balanced by a machine shop. they will balance the pressure plate and flywheel together. But otherwise yes normal
