So I’m back at the dealer again for the hard shift/slipping/shuddering on my denali 9 speed as the dealer thinks the shift to park recall would fix. But to think about it in engineering aspects, this is either a software issue or gearing issue. So currently it’s at the shop just gotta wait and see what they say. Perhaps it’s the same TSB as the new traverse/Acadia/enclave but well just have to see. On the bright side, they loaned us a 2020 Sierra Elevation with the 2.7T.

The Traverse, Acadia, Blazer runs the 9T65 transmission.
I think your Terrain has the 9T50 trans depending on which engine you have.
These two are similar but not the same.

I'm watching this trans issue to see how they fix it before I buy my next one.
