[TR] GT6 trans bearing noise on launch -

[aribert neumann]

Edward:  Thank you for your response.   I've been a bit late in responding
- ice storm on Wednesday, we are scheduled to have power back on by
Monday.

You raised a number of valid points that I had not considered.   I was
really hoping that there might be a consensus response that the chipped
layshaft would probably work.
