On a 4 cycle, 4 cyl it will have 2 places 180° apart, a 6 cylinder will have 3 places at every 120° of crankshaft rotation on an 8 cyl 4 places every 90° of crankshaft rotation. This is the reason the OP has major damage spots on the flywheel.
That’s sensible. My angle was as much coming from my initial concept that I’d rather wait to replace the flywheel until I had to remove the AT for other more significant service. But what you say makes sense. And I should do the guibos anyway…
