converter balloon

[flyinlow]

what does torque converter balloning mean?  Why is it hard on the thrust bearings?

[Challenger340]

Means the Convertor was getting abnormally HOT during operation, causing it to "expand" longitudinally, excerting pressure forward on the Crank ?

Generally NOT an issue, unless very High Stall Speeds are seen for long periods ?

Whats the application ?
WTF happened ?

[John_Kunkel]

The term "balloon" refers to the swelled bowls of the converter, resembles an inflated balloon.

It has less to do with temperature than excessive loading or operating a torque converter at very high RPM, this can cause the shape of the converter's housing to be physically distorted due to internal pressure and/or the stress imposed by centrifugal force.
