Flip the pill vs. tap and plug?

[RLC2020]

I'm doing a full service on my trans this weekend. Amsoil fluid, new filter, and I'm either going to "flip the pill" or tap and plug the thermostat housing. Not sure what method would be best honestly. I can't do the newly release thermostat replacement because I have a 2015 with the clip style cooler lines, so I either need to flip or plug my existing housing.

I live in Florida and it never goes below freezing where I am, I do tow regularly, but nothing over 4k lbs 99% of the time. Is flipping the pill going to do what I need, or should I take the extra steps to tap the housing and install a plug?

TYIA for any input.

I tapped mine it was easy enough, just seemed like there would be better flow doing that

I ended up just flipping the pill. Turns out that my 2015 actually has the bolt on style lines instead of the older clip style. I may buy the newer style thermostat housing down the road, but for now it's running much cooler. Didn't go over 135 on my way to work this morning!

Flipped mine. Didn't get past 172 towing enclosed 4600 pounds. Stays around 120-130 cruising around town. I would see 195-200 easily around town not towing before I flipped it.

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.
