bleeding oil question 5r55e

[Giacomo Verdi]

question: my mechanic has tried to wash with pressured oil my 5r55e transmission, but said me that its oil cooling system is broken why he can't bleed the oil from the radiator (from the trasmission).....

I was surprized....so I'm making some research about the 5r55e transmission, and I found that information: the radiator loop will be activated after the engine temperature is around 150 °F.

That information can be the explication?
The engine was cold during the oil bleed....

That is correct, it doesn't open until the system is warmed up to reach optimum operating temperature. Not to worry though, if you had a transmission flush preformed on this transmission at high mileage odds are you will need to replace the entire transmission shortly due to an impending failure caused by the flush.
