1996 yukon poor mans flush? Anyone?

[hshark]

So I did a search and couldn't find anything specific to my needs. I have a 96 GMC Yukon with the famous 4l60e. I've replaced the trans oil and filter a couple of times before on my rig. being that I'm sitting at 100k on the odometer I wanted to do what's known as a "poor mans flush". My problem is though I've read elsewhere with newer Yukon's on ho to do this and I'm sure it's similar on my OBS I wanted to make sure. I have 4 different lines connected to my radiator. 2 on passenger side and 2 on drivers side. I'm unsure what line to disconnect and attach a hose to drain my trans and converter. Any insight would be great. Thank You!

The larger lines are the oil cooler for engine oil not transmission fluid the oil cooler lines are on the drivers side and the transmission cooler lines are on the passenger side. Good luck

So would this be how to do it (see below)? I'm assuming the fittings in the write-up is the same for the OBS. GM doesn't like change a whole lot....
