trans cooler line Identification

Can anyone tell me which oil cooler line is which on the 5r55e? I need to flush the transmission cooler, and want to be sure I connect the cleaner to the intake line for the cooler.

The top line is the return. The lower one is the outlet. Check this link for more information: http://transmichigan.com/html/cooler_line_id.html. This link is # 52 in my list of useful threads.

Thanks, BB. So the top line has fluid running From the Transmission TO the Cooler? And the bottom line has the fluid running from the Cooler TO the Transmission?

It's the opposite of this as stated in post # 2. The top line has fluid flowing from the cooler to the transmission. The lower line has fluid flowing from the transmission into the cooler.
