The box came with a used TRD clutch with a metal faced clutch disk. The problem I`m having is that when I ride the clutch say when parking or during a hill start, it makes this horrible metal grinding sound and makes the whole car shake.(can`t be the release bearing cos that`s new) I was told that the TRD metal clutch disks made a bit of a racket but the car as it is isn`t very street drivable. I`m hoping someone could advice me on weather a new metal clutch disk may ease the situation, or if possible replace the metal one with a stock Toyota R154 disk(keeping the rest of the TRD clutch components). Another problem is my speedo readings, which have become erratic...will replacing the speed sensor fix this or could it be some other problem? Anyways, appreciate any advice you may have...
