I sent my factory 69 Dart rad out for a new high efficiency core and the rad shop told me my transmission cooler in the lower tank was collapsed. There was no external damage to the lower tank.
Has anyone ever heard of this before?
The only thing I can think might has caused this was I installed threaded plugs in the transmission cooler when I was running a 4 speed.
Do you think that might cause the tank to collapse due to temperature changes and no venting?
