What did you do to your 2015-2020 K2XX Tahoe/Yukon Today?

[the 18th letter]

There is always the story of the transmissions that work until you change the fluid which gets rid of all the friction material built up over time.

This is what my trusted transmission guy told me about by 99 and as a result it’s close to 160k with no fluid change or issues, knock wood lol. Many others will tell you it’s an old mechanics saying.
