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

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

Just an update. My "thunk" has gotten to the point that it occurs every time. So took it to dealer today. After riding with the tech and able to reproduce the noise, I gave him the service bulletin number.
Invoice comments are "performed JTB00395 updated TCM software and re tested. Noise is no longer present"
I drove home (1.5 hours) with several stops. NO THUNK.....YEAH

Just curious, how much did the dealer charge you for this? It's my understanding that TSBs are not covered for cars out of factory warranty.
Thanks

I have no idea if it would cause damage and I failed to ask the tech. I work under the theory that if something is getting worse or more frequent then it eventually is going to cause a problem. If it just intermittent and not getting worse I wouldn't be too worried, but mine got to the point that it happened every time I shifted into park.

TSB JTB00395NAS1 for my 2013 XK
Had the ' clonk' in Park issue addressed per the TSB at the local JLR dealership. I asked the Service Writer to first see if it was already updated and to proceed if not. They did the work...
So far it seems to have cleared up the noise.( $240.00)
l talked to a number different Service departments to find out if it would create a problem if NOT performed...and the responses were all essentially the same, " no, not an absolute necessity, will not do any damage".
One advisor said it allows a " friendlier communication between the TCM and the PCM".
