Is this common?
Almost every time i put the car into drive or reverse after leaving work, I get a thud or clunk once the gear engages and you can feel the car lurch forward.

Thanks

Check with your dealer to see if the latest technical service bulletin for the transmission needs to be applied to your vehicle. It'll fix the lurch.

I find that I have a clunk when I am just cruising with my foot on the gas and when I remove my foot from the gas petal and re apply there is a little clunk. Almost like there is a little play in the transmission/driveshaft/rear end and its catching up when a apply the gas petal. I have a 2015 , don't know if the TSB would apply.

Here is the one for 2015. I have a 2015 and had the revision done. Similarly, I had the coasting, harsh downshifts and the flash fixed that.

The TSB fix may correct the issue with your "thud/clunk" by accident, but it sounds to me like the TSB is about correcting rough downshifts in the A8. Your issue sounds more like either excessive play in the ring & pinion or a sloppy U-Joint (i.e. excessive play in the driveline) since you didn't complain of downshifting issues but rather a thud/clunk when you put the car in gear. I suspect your problem is unrelated to the problem targeted by the TSB

Do you have any downshifting issues during 6-5, 3-2, or 2-1 coasting downshifts? If not, then I suspect your issue is more of a mechanical than an electronic issue as stated above. Another relevant question is, have you altered the differential in this car? Maybe 3.09 gearing?

In the event of excessive driveline play, the problem would be more pronounced when the vehicle is stopped as in shifting into drive or reverse, and while still noticeable while moving, the problem would be lessened while the vehicle is in motion.

Interesting timing of this post/thread. I was backing out the other day and just moments after, the rear rend made a loud groan or rubbing sound. I immediately hit the brake, as my daughter and I both thought we backed into or over something. Nothing was there and it has not done it prior or since. It was very cold that morning....not sure if that had anything to do with it.
I do have the rear end groaning at low speed and acute turns that many people have noticed. Have not taken the vehicle in for inspection on that as of yet.

TSB for that as well that applies to 2015-2017. It's a differential fluid swap with addition of LSD additive.

How about when you first start the car and drive off ...the transmission roughly shifts for bit then immediately becomes smooth...? Is that normal? Transmission fluid getting where it needs to go or low ??

That's normal. Fluid needs some time to warm up.

as ray said, thats normal. mine does it as well until the first shift, especially if the car is cold.

It doesn't do it really on normal shifting, but it definitely does it when putting it in gear whether its drive or reverse.

It seems almost like drivetrain slack and when putting it in drive from park, it ends up taking up the slack in the drivetrain.

This says just for the Challenger, does it apply to the Charger as well? Mine does clunk when going into reverse.

There is also a TSB for the Charger regarding the differential fluid swap.

So when there is a TSB on the vehicle, for example the rear diff groaning noise, when I take it in to the dealer and complain about the noise is that covered under warranty or is it under my dime to fix the problem because it's just a TSB, not a warranty issue?
