Sorry if this has been hashed out before but I am still wondering if others are getting a driveline clunk when rolling to a stop as the transmission shifts from 2 to 1st? Hope its nothing more than annoying.

No clunk on mine but I don't even have 200 miles on the truck yet.

I get the clunk in that situation only when I'm in tow/haul and I think its the convertor unlocking... or something like that.

No clunk in mine at 2300 miles

 

[Rams-n-Hogs]

No clunk in mine at 16K miles.

No clunk that I've ever noticed and I'm at 13,000 miles.

I have the clunk and have had it since day 1. It doesn't do it everytime I stop or start though.

That is the same as mine. I would say I get it about one out of every three stops, maybe less sometimes. It doesn't seem to matter if its in tow/haul or OD.

Seems to me its the transmission not releasing the pressure correctly downshifting from 2nd to 1st? not that I now a hole lot about auto transmissions though.
