I second that. :D

For us with the 8 speed it would be nice to know if it in fact is the brake switch or the trans update that will fix the hesitation. I doubt it would be a combination of the two. Like Basil135 had both done and problem solved, but which one fixed the issue?

It could be either causing the issue, could be both but as you said unlikely.
Get dealer to change the switch and upgrade the software anyway.

With the dealer doing both at once, you are correct in saying it is hard to know which fix did the trick.

However, I would think that the software is the more likely problem solver. In saying that, by adjusting the brake light switch, I presume that then makes the lights come on, and hence the car knowing something is happening, either earlier or later. We would only be talking milliseconds here, but it could be enough.

So, at the end of it, MAYBE the fix IS a combination of the two. Adjust the point that the car finds out you want to brake, and then have the transmission do its stuff a little quicker.

Thanks. It has only happened to me once. If it was the trans then it should keep happening. Maybe my brake switch 'sorted itself out'? I have my 1st service due in July so I'll get the brake switch done only as I'm happy with the way the trans works as it is.

How much does the dealer change for :
A) transmission software update
B) brake light switch change?

I had mine done under warranty, so it didn't cost me anything. The servicing dealer was helpful, and did his own research with the info I provided.

Give yours a call, and if not under warranty, they should be able to give you a price. I would suggest that it would only be an hour or so of labour time.

Well, nearly 6 months on, and a quick follow up.

I am happy to report that the fix described above seems to have done the trick.

I no longer have the amount of hesitation that I did before. To say that it is gone totally would be an overstatement, but it certainly is heaps better than when I first posted.

So, it would appear that this is a long term fix, and the car hasn't reset anything to make it go back to the way it was.

:D
