Transmission thunk on start-up
#1
First time I have ever heard a car do this. When starting my 2008 528, the auto-transmission will thunk, sometimes enough to feel it besides hear it, and at worst it'salmost a metallic sound; other times barely noticeable.
Took it in. Dealer said they ran a PUMA case on it, whatever that is. Then wrote up that it is normal depending on the tolerances of the tranmission/engine. Also wrote that replacing the transmission would not solve (which seemed a little extreme to me). But then, wrote that a 'software' fix is coming in September to correct. So...in one hand it is 'normal', and in the next it is going to be 'fixed' (via software?). Not sure if I believe this.
As I have had many cars, including BMW's, I am concerned about this noise and am inquiring if any one can vouch for this "normal" sound' when starting their engine?
