Kick Down Clunk!

[Claws]

Hi All

 

A couple of times now I have hit the pedal to the floor, (sorry didn’t think to take note of speed at the time but my guess was about 30 first time, and about 70 second time) there was a big old thud / clunk sound from the rear of the car (it seemed to be anyway) the revs shot up, with a delayed response in
acceleration, a couple of seconds I would say (I know there is a slight delay) and the acceleration wasn’t particularly quick either. She may have been in sport mode, I honestly don’t recall.

I am quite happy with the way she accelerates just by pushing down on the pedal normally, you can feel the gears change down when you get to a certain point of pedal travel, and then a push in your spine, into the back of the seat as she moves past other vehicles.
 

Going back to the clunk, and not wanting to be a harbinger of doom! Gearbox? Prop-shaft? Diff? all? nothing at all to be worried about?

 

As always, I know one of you guys will have some ideas

 

Thanks in advance

I don't get the thud, but I do have the same problem with revs shooting up before it changes down a gear and then it's not very responsive. I did read in another forum resetting the Transmission Control Module can cure it. But I haven't got round to trying it yet. It also costs around £65 to have done.
