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.

Doesn't the trans filter catch the friction material? Or should a guy delete the filter that way the friction material stays floating around and keeps "doing its job".

I'll stick to changing my fluid yearly in all my automatics.

"in my opinion" if you change it somewhat often (like I do) you are fine, it's when you decide to change it after the "the book said 100k" then you are asking for trouble
the 100k gm notates in the manual is hogwash and is under the presumption you drove it 55mph or less for 100k, never towed, yada yada.
to each there own, but I change mine about every 20k, why? well for one when you have a warranty from a shop (not gm) most of them require it in order to keep your warranty valid.
so why on gods green earth would a 3rd party shop say that if 100k is in the manual???? put 2 and 2 together

When I took my 15 to the dealer at 98k, for the manual suggested, service of changing transmission fluid the dealer refused advising “they see too many problems” changing the fluid in high mileage vehicles. “But the book says 100k yadda yadda” they wouldn’t do it. Mind you I had no issues and called myself doing preventive maintenance.
