Ticking from Torque Converter?

[SWeddell]

I notice that when my torque converter on my 04. 5 is locked it makes a ticking sound. It can't be heard while under acceleration, but is quite noticeable when off the gas and say getting off the freeway. As I am coasting along the offramp there is a ticking noise and as the truck slows down enough and the torque converter unlocks the ticking goes away. Any ideas? Is this normal and I just started to notice this for the first time?

noticed the same thing on my 06. especially noticable when I have the box on.

I hate to say this but could it be a cracked flywheel?

Have either of you had any work done that required the trans to be removed? I was thinking loose torque converter bolt, or improperly installed inspection cover.

I assume you mean flexplate since its an auto, but regardless wouldn't that make a sound all the time since that would be spining with the crank? The ticking only happens when the TC is locked.

I had some transmission work done around 700 miles as reverse went out. I now have 42,000 miles and I just seemed to notice the ticking in the last couple thousand. Sounds like it might be time for a tip to the dealer and take them for a ride.
