Flip the pill vs. tap and plug?

I would love to do this (new Tahoe owner here!!) but would like to watch a video or read a detailed thread if possible.
Anything out there like this?

this is currently the easiest method, when I did mine I just pulled all the thermostat parts out and tapped it and put a bolt in it and then put the cap back on.
whatever way you choose just be sure that snap ring is in properly or it could come off going down the road.
easy to do, when you take it off you might loose a few ounces of fluid so just have a rag handy, if the lines are dripping you can put a little piece of plastic bag and rubber band around them to keep it from leaking while you do the thermostat part

I installed the newer revised lower temperature trans thermostat and sold the old one on eBay to recoup "most" of my costs. That is the route I chose to take versus having no thermostatic control at all.

when I fixed mine to no thermostat it only dropped it by 20 degrees, so instead of always running at 200-220 it would run 180-200, adding a tru cool and a deep transmission pan, turning off the shutters helped a little more bringing it down to a more reasonable 145-160.
I do not drive like a normal person, most (99%) of people will not experience those high temps

Mine used to run about 180-190. Now it's more like 140-150.

I watched the video linked in this thread, and he only discusses through 2018. Is the thermostat mod recommended for a 2019 also?

On my 2019 I've been watching the temps and so far I've seen a high of 180. That's in mostly a high of 70 degree weather. I looked at the thermostat and it doesn't have any markings so I'm guessing it does have the higher temp unit. Probably be changing it out before summer. The TSB that recommends this covers through 2020.

Did anyone try this on a 10 speed yet?

Through 2020, I replaced mine on my 2020 XL with the updated thermostat. That, along with fresh fluid keeps the temps down.
