Default TSB JTB00395NAS1 -Transmission "Clonk"

Has anyone had their transmission make a "clonk" noise when shifting into park? I see there is a TSB for it - excerpt is posted below.
Bulletin: JTB00395NAS1
Component: 103100 power train:automatic transmission:control module (tcm, pcm) Summary:"situation: on vehicles fitted with the 5.0l naturally aspirated
v8 engine only, a 'clonk' noise may be heard when selecting park (p).
cause: this may be caused by a transmission control module (tcm) software issue."
Mine makes the clonk noise. Has anyone had this TSB done?

If I get a Topix subscription are the updates available so that I could do it myself (with the SDD)?

thanks

I had and intermittent "clonk" on my 12 NA. It was never solved because, as is typical, it would not clonk on demand. so the dealer never experienced it. I also have it on my 13 XKR. Next time it goes in, I'm going to have them take a look at it.

Let me know what they say. Mine is intermittent as well. The TSB says it only affects normally aspirated cars.

Mine won't be going for a few weeks. I will try to remember to let you.

Ralphwg, did you ever get this worked out?
My '12 has a "thunk" when or more accurately right after putting the transmission in Park. This seems to happen only when hot and is not affected by moving to Neutral first, so it's not something that occurs when moving from a gear to P.

Mine has done it about 3 times in 3 years. I haven't had it looked at.

I still get it occasionally. The dealer has not been able to replicate it. It happened a few days ago for the first time in several weeks.

Add me to this crowd as well. I've simply attributed it to particular conditions each time. If anyone finds a solution though, I'd like to know.

How does one advertise a part on this site....I just bought a 1997 xk8 with a blown engine and a rebuilt tranny with 20k miles on the rebuild. I find it hard to believe that someone paid $7200 to rebuild the tranny but that's what the receipt says. I'd like to sell it to help with the costs of replacing the engine and trans. Could someone point me in the right direction to accomplish this? Thanks....newbee Al
