Default Re: Knock. A question for Graham or Marc

The transmission noise of a single mass equipped car is well documented up to about ~2k rpm. Is that noise, under various load and speed parameters, generating false knock throughout the rpm range as we shift and move on and off throttle without the dampening affects of Dual Mass Flywheel? Food for thought.

Yep, think that's the question I was asking before. The problem is, false or not, it affects the performance of the motor. And that brings up the issue of the correct trans fluid.
