Hi all,

I just saw this happen the other day. I was on the highway in Econ mode and doing 70 or 80 mph. At some point I drifted up to around 90mph (shh!) and noticed the RPMs were kind of high at around 2300. So I hit the paddle to see if I was in 10th gear. Nope, 9th. And it would not let me shift to 10th--the 10 would flash a couple times and then revert back to 9th. After I slowed down to 80ish, I could force the shift.

I wonder why...

Could it possibly be related to being in Econ? Did you happen to turn Econ off to see if the same occurred? Just wondering if because of the speed/RPM the computer somehow was determining that was the most "economical" gear to be in. :unsure:

That seems logical, but I didn't think the E-mode would be that heavy-handed. I know under other circumstances (lower speeds) I can force a temporary shift to another gear (which, since it wasn't auto-selected for me must be considered "bad for economy" by the system), but it takes (and then switches back when conditions change). E.g. heading downhill, I might downshift to slow a bit, then when the road levels out, it' goes back to auto and whatever gear is "best". This was an outright refusal to shift up, at a speed that would certainly justify top gear.

Last Fall we did around 830 miles in one day in our 2019 Touring. Toward the end of the drive, at around 80 mph, I put it in Sport to see what gear I was in. Eighth. Makes me wonder if I'll ever get it in Tenth.
When you put it in Sport from normal it will usually drop a gear or two. If I'm cruising steadily in normal at 70 (around 1720 rpm) I can click up the upshift paddle and it shows me I'm in 10th, then put it in Sport and it drops gears and turns around 2300. It drops gears and spools up so it's ready to play the instant you put your foot down

I Noted this a few Times - It Happens @ High Speed - Small Issues are ~
1. Air Pressure in Tires
2. Going to Larger Dia. Tires
3. Fuel Your Running
4. Head Wind
5. Power Being Requested
6. How Level is the Road Really ?
7. SPEED trying to Maintain
8. Generally Over 100+ , but have seen it @ 95Mph
9. Alignment . .
Like I have Stated didn't need 4 Over Drives . . Seems to be Most Eff% from 55~85 - that would change with Lighter Wheel & Tire Package ..

With the 10 Speed Auto, 6th gear is direct drive with 7, 8, 9, and 10 all being overdrives. Depending on the load on your car (car full of people, AC blasting, etc), going 90 MPH might have the car drop into a lower overdrive gear (which is so weird to think, my first two cars only had 4-speed autos, now I have a car with 4 overdrive gears).

And @alorentzen is right, Sport mode will keep the car in the first 8 gears only. You can manually shift up to 9 and 10, but if left to auto mode (you can just pull and hold the upshift paddle for a couple seconds and the computer will go back into Sport Auto mode) it'll keep you in the lower gears for responsiveness.

I've posted about it before, but the one thing I thought was interesting is that you can't get the car to go into 1st gear. Try putting the car in Sport and paddle shift down when coming to a stop. No matter how slow you're going, you can't get the car to engage 1st gear. But when taking off from a stop, it'll start in 1st gear. Someone mentioned here (or reddit...?) that 1st gear is probably a "launch gear" and the computer prevents the driver from shifting into it.

3.61 Gearing from Mini Van - might do it ..
3.84 Gearing from Manual 6 Speed would take care of that ( Look more Two ) OD Gears then ..

Now Has anyone Run 7th Gear all way Out to 6500 Rpm's or more ? ( Tuned ) of course on some Lonely Airport

The fastest I have gone is 145.It was for sure on a lonely airport. I don't remember what gear it was in. Was just surprised how quickly it got there considering the amount of power the car has. I feel that the 10 speed makes the car much quicker than a similar car with less ratios. and I have noticed that anywhere above 90-95 mph my car will not use 10th gear. My guess is they don't want to load the motor in 10th gear at high speed.
