Just installed a TKO 600 in my '69.
Clutch, PP, TO, pilot bearing all new as well. I am getting a rumbling, grinding noise when the clutch pedal is up in neutral, it goes away when the pedal is pushed down. The tranny itself shifts flawlessly and there is plenty of freeplay between the TO and PP.
I was thinking the TO was bad, but I have gone under the car while the noise was present and moved the fork up, down, in, out all around and heard zero change.
I have read that this is common with Vipers.
Any TKO users hearing this same noise??
Could it still be a bad TO??
