2025 Yukon Denali 6.2 Transmission

I know they are not. However, it seems that both are American (yours and mine). I know foreign cars have issues, but all the foreign cars I've owned have not had issues with the transmission. Most of my family members all have foreign cars and they've never been to the shop for a transmission issue.

I understand there are problems, but you'd think a large company like GM would have this dialed in by now.

I’ll have to agree with you on that as all foreign cars I’ve owned - Lexus, Subaru, Toyota, Mercedes, and Audi, have all had problem-free transmissions. Also, as a side note, the transmission in the GM full size SUV’s and half ton trucks was co-developed with Ford lol.

Yeah, that's interesting.

Any update?

Does the 2025 have the 10L90 transmission?

I'm starting to look at 2025 models, which is why I'm curious about your issue.

GM and Ford have the same 10spd mechanicals; they developed it together. Different controllers and valve bodies…Single best thing you can do is the recommended maintenance on them.

BTW, Nissan has had its fair share of transmission issues w/ their CVT. Honda had issues with their automatic in the 2nd gen Odyssey, so nobody is immune. It’s a machine, made by man…it will break.

Agree, nothing is perfect. Having an issue is one thing. Putting out a bad transmission with a poor design and known failure is not the same thing.
