2010 MC Powershift transmission "clunk"

[Midnight Man]

I have, as suggested, turned the key to the position immediately prior to actually starting the car, and left it in that position a few moments prior to actually starting the car.

This simply changes the timing of the event to occur more quickly after starting - ordinarily without using this tactic, the noise is heard a couple of seconds after starting - with this tactic, it's almost immediate. Varying the length of time the key is left in the "pre start" position makes no difference to the fact that the noise is then heard nearly immediately after starting.
