I'm not a transmission guru but yes, it tracks how you drive (throttle, etc) and "adapts" shifting points and speed of shifting in order to be closer to your driving style.
That is the reason when I will go drive the Envision ,our toad and wifes car, it is shifting like if it was just in a Nascar race, sharp and fast....

That little foot size 6 is made of Uranium....

Two questions Beau might know:
A small block Chevy 350 haas a resonant speed of, if I remember right, 1851rpm.
I believe it relates to bore vs stroke.

This is the rpm when it all kinda falls apart/comes together as a unit. It's palpable.
It could relate to the speed in rpm you can shift a standard transmission without using the clutch...everything is in synch for just an rpm or two.

So,
what's resonant rpm on our v10 and on the new v8?
I think this may be the feel some are feeling.

On a GM 4sp auto trans you can undo the trans learning by
0 to 61mph as fast as you can
Then stomp and hold the brakes to a stop.
Do this three times.
Trans resets.

Our sb avalanche was:
Drive like a turd and it becomes a turd.

My 8.1 avalanche has a trans tune that negates the learning.
Will a 5 star tune wipe out the
'Be a turd' function?

The primary resonance speed of the V-10 is about 1,850 rpm. That is when my aftermarket exhaust system hits the bottom of the coach. The two balance shafts are there to cancel bad harmonics at higher rpms. The harmonic at 3,700 rpm is noticeable, so I avoid that rpm. I have had the engine up to 4.900 rpm with no noticeable vibrations.
Yes the 6R140 is a learning transmission. Just disconnect the chassis battery for 12 hours and go for a drive and you can feel what the trans forgot. For me, the 5 star tune was to correct the shifting schedule of the 6R140 and not about engine power.

PS What ever speed you chose to drive is ok as long as your are able slow before hitting the idiot who is about to miss his right turn or the one merging at 30 mph 50 ft in front of you. No, dual air horns do not make then speed up, although air horns do make me feel better.

Thanks.
I hadn't noticed resonance or secondary vibration on the 24.1 because we just drive it like we would any other vehicle. Turn key, engage trans, go.

A mazabazillion cumulative miles on these v10's means I don't need to play engineer.
I just say giddy-up and it seems to do its best.
We wail on it if the need calls for some wailing.
We're not worried about only getting 230,000 miles on it instead of 250,000 miles.

That v10, based on that megazillion miles of Uhaul and goof drivers, stoned and stupid temp drivers for local delivery, field placed 24hour water pumps running 4500rpm for months on end, doesn't give a flying patoot how you drive it.

You beta testers with that new engine...you'll have to decide what to do.

About speed.
If you can't keep up with traffic, get out of traffic.
Mazzillions of mile, at highway speeds on an rv sized vehicle happen every. Single. Day. Worldwide.
Front tire blow out? I posted a video a while back if an rv running on a front rim at 85mph for about 30 miles. She was very drunk. Excellent driver though. Be excellent.

Do the speed limit. It's easy.
A speed limit is designed so the worst half blind, partially drunk person can navigate the road at that speed.
A speed limit isn't an upper tier...it's the lowest common denominator.

The hurry isn't mine.
The hurry seems a hurry if you're afraid of your vehicle.
The hurry is actually just the flow of traffic... That 99.9999% of drivers accomplish.
I will not impede.


Not trying be mean, just trying to understand how being an impediment is some right of retirement.

Have you ever driven in Texas on two lane side roads, lane that is two feet wider then a semi, with four foot steep drop off on each side, and no shoulder or pull offs with a 75mph speed limit? I suppose people in Texas get used to it, but the semi's coming at us used a foot over the center lane markers! That was white knuckle driving. The couple that managed the RV park was there for two years and stayed because they were afraid to drive their rig out. Our mirror was dinged by a semi. Just a scratch, but he was not going to get back in his lane at all and I could not move over to the right any more. My dully was on the pavement edge. 75mph was not designed so the worst half blind, partially drunk person can navigate the road at that speed. Then again it was Texas!

I thought everything, including road lanes, is bigger in Texas!

When a Missouri road sign designating a curve to be 55mph, it's not a warning, it's a
'betcha can't do it'
Type challenge.
(Texas used to have road signs at exit ramps that said:
'Our 55mph curves ARE 55mph curves. We have flipped the best')

If you can't operate a vehicle as well as the 5,000 or so truck drivers, every daylight shift, who navigate that road.,.get off of that road.

Inability when compared to every other vehicle the size of yours is absolutely not an excuse.
Get better at driving or quit driving.

I can't fly a plane nor drive formula one.
Guess what I don't do. I don't fly a plane nor have a formula one car.

The validation of the bottom tier of drivers is boggling.
Get some practice and drop the woeful act.

All I ask is for you to be an AVERAGE driver in your not inordinately sized vehicle. Do as well as the far less than average stoned and stupud lowest of the low, looking at porn on his cell-phone teenage semi-truck driver, who navigates the same traffic as you...without incident.
Drive the flow of traffic, or get out of traffic.

Yes, the picture shows a passing lane on a reverse banked curve.

(Supplemental paper map as an enhancement to our usual three+ digital maps.
Farm roads. The screens weren't big enough to effectively see the 100 different roads we took, and see where our outcome was shifting to get from Nebraska through northern Missouri. But the paper map couldn't tell us where to find a tiny antique store in someones front room in Pickledorf)

Frankly, you should drive in a manner, and speed, that you feel comfortable with. To say "you should stay with the flow" would mean that near my house on the freeway, I would be going at 75+. If you are flowing with the right lane traffic as other commercial vehicles, then fine. But do not be told you must drive a certain way or be called a bad driver. Me personally, want to see all of you get there safe and not white knuckled stressed out when you arrive. Some of you may not agree, but you know, you can drive the way you see fit, and I will do the same. Happy camping everyone. I'll post some pics of our fireplace install when complete.

So when I disconnected my batteries and installed new ones, the f550 dash showed a wrench. I drove it around the neighborhood for awhile, the wrench disappeared. Was that the tranny relearning? Yes, I had the batteries off for about a day.

Therr must be a low end to the limit of tolerance.
If they're comfortable at 45mph in that 75mph traffic, do they get to do that without being called inadequate?
35mph?
A dead stop to do a lane change in a 75mph zone?
35mph merge into 65mph traffic?

I have a line at average. That's seemingly fair. Average is the cusp of below average.
But
We may need to get ludicrous. (sort of. I have not exampled anything anyone here hasn't seen and deemed that driver to be stupid)

When does 55mph in a 75 zone get acknowledged as inability and obstructive?
When does 35mph in a 75 zone get recognized.

They're the all the same to me.
Dangerous and inadequate.

I sway easily.
Tell me you honestly think a 35 merge in a 75 is ok, that 35 in a 75 is ok, and I'll try to understand why you all'd think that way.
(Then we'll move the argument out of ludicrous and into inadequate.)

I missed it... have you used the Manual mode in your 6 spd or the function that drops gears? not sure the application for this, to remove a gear in your shifting. Maybe if your towing something?

I used manual in Gatlinburg mountains, NO way auto can go up and down those mountains near Dollywood...

Well I am quite surprised that you don’t have a F1 in your garage! Shall I check with my friend at Penske to see if they have a spare they would trade for the T Bird?

I am an old gray haired fart and folks expect me to drive slow, all through I don't call 65 MPH in a motorhome slow, so I drive 65 when on multiple lane highways. Those that don't like it can use the left hand lane to pass me. It is my experience that no matter how fast you drive there will always be an A-hole who will follow 6 feet behind you and flip you the bird. More than once I have been doing 80 MPH in my truck in a 60 MPH speed limit zone only to be passed by someone I pissed off because I was driving to slow.
