Tranny re build

[hitmachine101]

THanks earlier for the info about the transmissions and the swap ideas for the 6 speed on the 1997 M3

unfortunatly im a poor college kid so im just gonna have to rebuild my tranny

now the things im hearing is a rattling when the the car is idoling with the clutch pedal up, when the clutch is to the floor the rattling stops

what could this be? main bearing? if i could get a good guess at what it is before i rip it apart that would be helpful

Does the car have an aftermarket lightweight flywheel?

[hitmachine101]

I dont think it has a lightweight flywheel

The previous owner didnt mention that but it is possible that he installed one
because the clutch is a ceramic stage one street clutch so i know he at least had it apart at one point or another

could it be the throwout bearing? it has 80K on it

[Jeron]

If he put in and aftermarket clutch surely he put in a lightweight fly.

It explains the cause although I disagree that it can be so easily "fixed".

That is exactly the noise I am hearing.

saved me from ripping apart my tranny ha ha i would have regreted that
