I've got an '02 4R70W and the bell housing has a plug in it so you can see the torque converter. I rotated the engine around but no drain plug to be found. Is it hit or miss on which models have a drain plug for the t/c, or why doesn't mine have one?? Is there another way to drain it besides taking it somewhere for a flush...which I'm not doing!

 

'01-'02 was the crossover for having or not having a plug. If you don't have it you gotta flush through the cooler lines.
