Question for Techs

[Racer-X]

Well, as you know the radiator blew into the tranny cooler. I then drove it some 30 miles AFTER I felt symptoms and probably about 200 miles after it happened. This fried the tranny to the point GMPP opted to replace it.

I don't have the paper work in front of me but a few things on the list of things changed.

Transmission assembly
Radiator
Overflow tank
All hoses (including the ones to the heater core).
clamps

Cooling system was then flushed and filled. It's very obvious to me that all of the work on the list was done. Tranny is sparkling clean as are radiator and hoses etc. Fluids are clean and free of cross contamination.

Also as you know this is the second time this has happened, at this rate I'll never have to change my fluid.

The reason I'm wondering if the torque converter was changed is from what I've heard, there are some kind of fins inside of it that break off. When that happens the fluid super heats and when it finally reaches the radiator, it blows the tranny chamber into the coolant.

This is the reason you never see the temp raise on your tranny before it happens. The tranny gauge never budged and I checked it often when I began having trouble.
