Shift points

[ADVAW8S]

I decided today on open to let it rip. Doing 55, stepped on gas and the QM took off. Not push back of your seat but it got going pretty quick. The transmission went from 8 to 4 and got me up to 85 pretty quick. It got me thinking about the transmission profile.

When I got off the highway, I started paying attention to the shift pattern. I noticed the Grenadier shifts at around 2200 rpms. I put manual and noticed I liked it better shifting at around 3000 to 3500 rpms. I was listening to engine and shifting like I have always done driving manuals. Probably in my mind, I actually think the engine liked shifting later versus early. The gas mileage seemed better as sat closer to 3000rpm.

I also wished the car would start in 2nd gear versus 1st. It seemed a better take off versus the 3 seconds it's in 1st.

I asked AI for thoughts.

For optimal performance and enjoyment
The B58 is known for its strong torque delivery and smooth powerband, particularly in the mid-range RPMs.
Maximum torque is typically available at low RPMs, around 1500-4500 rpm, which ensures responsive acceleration.
Some drivers find the engine to pull hardest around 4000 RPM and up.
The B58 boasts a 7,000 RPM redline, indicating its ability to rev.
The engine is praised for its smoothness even at higher RPMs, making it suitable for both performance-focused and comfort-oriented driving.
For everyday cruising and fuel economy
For casual driving around town, shifting between 1500-2500 rpm is generally recommended for a smooth ride and good torque availability, according to one Bimmerpost forum user.
It's generally advised to keep the engine below 3,000 rpm for optimal fuel economy and to avoid running below 1,500 rpm, according to HowStuffWorks.
Eco mode in some B58 vehicles might feel "neutered" to some drivers.

Isn't this gearbox an adaptive box?

Yes, I guess if you drive it like you stole it it will learn what you like and behave accordingly..

I believe that you can get the gearbox mapped just like an engine to make it do whatever you want...

Have you noticed that when driving on steep downhill sections on road i.e in the mountains it holds on to lover gears ??????? you have to manually shift up a gear.

It's

Somewhat of an urban myth that transmissions (and engines) adapt to driving styles. They certainly adapt to many variables including clutch bite points, brake bands, hydraulic pressure etc to give the optimum gear change speed. Most link to the engine to momentarily reduce engine torque during gear changes to smooth the changes.

So yes, the transmission is adaptive, but perhaps not in the way that many think.

Very much doubt this.

I also wished the car would start in 2nd gear versus 1st. It seemed a better take off versus the 3 seconds it's in 1st.

I think with manual mode this is possible.

Yes, it holds onto the speed at which you take your foot off the accelerator or set at the speed from initially braking. Excellent feature.

Been my bitch from day one. It likes to be in too low of a gear for an automatic and going downhill it drives like someone that can't drive a manual smoothly. It's like its in Hill Decent Control all the time. If I'm parked facing downhill on a steep hill, Which is common here, and pull out, i'll have to pop it into N and back to avoid having to accelerate to encourage the engine to up-shift.

The base programming is fucked up, and down low in the gears on a grade it's seldom in the proper gear for smooth operation of an automatic. I have a loaner while they are quizically looking at mine wondering how to fix the alignment, and it does the same damn thing. Same shitty 3-2 downshift, but at least there isn't a clunk. Other ZF* cars don't do this. It's definitely an Ineos issue.

Why? If I want engine braking in high range, I'll shift to M. My f350 has a button for selection of gear holding in high range.
