Dealership replaced torque converter on my '08 2.3 under warranty and now I feel a "miss" at idle that I didn't notice before. Could this be a balance problem with the replacement converter, or just my imagination?

 

At the dealership now, again - I suspect a bad converter was installed, but I haven't been called yet.

 

"Found torque converter to be misbalanced" FP Number: 4L5Z-7902-AARM. That took care of the vibration.

As for the leak: "Found torque converter housing to have porosity" FP Number: 1L5Z-7976-AA.

Replacing the fan belt took care of the belt noise I was hearing since the truck had 5k on it. And they washed and detailed my truck inside and out so I'm pretty happy right now.

 

What was wrong with the original torque convertor?

 

That's where the leak was thought to be coming from, but I'm guessing that the original leak was really the housing.
