• Hint: Use a descriptive title for your new message
    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my SUV" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your leather interior, please post in the Interior section - and so on...

Not shifting past 6th gear

Hello,

I have a 2023 Telluride LX with 4000 miles.

The other day I noticed that the engine was revving too high while driving around town. I was in Eco mode and autoshift. Shifts were occurring well past 3000 rpm.

I tried switching modes and that did not change anything. I am able to switch to manual mode and advance to 7th and 8th gear, but as soon as I switch back to auto, it downshifts to 6th gear no matter what speed I'm going.

I shut the engine down for a minute and that did not help. After shutting down for 15 minutes, that worked.

The vehicle was fine for about 5 days, but today I experienced the same thing.

I had the dealer check it out and since they could not reproduce it and there were no error codes, nothing was done. I plan on taking it back and leaving it until they fix it. This is a brand new vehicle.
