2008 Tundra 107K Transmission

Hi Friends,
I recently purchased a 2008 Tundra 2wd Limited with 107K miles. Looks like transmission has never been serviced. Prior owner indicated that the Tundra was used for regular towing. Has factory towing package with trans cooler, etc.
I'm trying to decide between a series of drain/fill; or a complete flush.
For those of you with experience, what is your suggestion?
Thanks,

drain/fill ensure you follow procedure to the proper fluid level.

 

I did a drain and fill a few times a couple hundred miles apart when we got ours at 96k. No issues at all.

Now I plan on doing the same every 20k or so and hope for a long lived happy transmission!

 

I had mine flushed around 100k. End result drives like new*

* had a little hiccup after initial flush, but got resolved after re-visit to dealer. Over 3yrs and 30k miles trouble free.

 

Drain and fill.
Here's 5 drain and fills from my 02' Sequoia with 156k miles when I first got it. Definitely not "lifetime fluid"

Sorry for the blurry pic. Far left image is first drain, far right is new fluid.

 

Looks fine, it just changed flavours from cranberry to grape
