I heard that the flywheel chatter can be removed by raising the idle to around 1300, and changing the final drive ratio to 3.9. Is this true for the JWT clutch/flywheel kit? Also, how exactly do you change the drive ratio's in a transmission? If I tell my Nissan dealer to do it when they drop in the new free transmission will they? I don't care about warranty anymore... it expires in 7 days lol.

 

Me first. The 3.9 final drive is not in your trany. It's in your rear differential housing (pumpkin).
