Great job and thanks you so much for doing this. I'm sure it was time consuming. I just have a few questions. First how do you do decide on when to set your next gear and your final gear will be?

and it would be cool to know if this is still best practice since the Jan 19 update?

I think a lot of people are confused about WHY people “flip transmissions” in GT games.
First off, this is 100% a Gran Turismo unique thing, it has no basis in real life, it’s purely about the way GT handles the numbers of transmission tuning. It’s basically a way of changing the min and max values that the game allows you to use for any individual gear, and it only exists because of the “easy mode” option of transmission tuning that is the Max Speed slider.
Adjusting the Max Speed slider changes the min and max values associated with each gear. So the basic idea is adjust the Max Speed slider to adjust the range of a given gear, then use the individual gear adjustments to set the RPM drop between each gear, and then use the Final Drive to fine tune the max speed of the car.
Still though, that doesn’t explain the WHY we do it. In short, the main reason to flip a transmission is to get more use out of more of the gears. Different types of cars benefit from different types of flips, even though you use the same basic technique all the time. Some examples of different types of cars that benefit from flips:
- narrow Power Band. A car with a narrow power band can benefit from a trans flip if the flip brings 1st gear and 6th (or whatever last is) closer together. This will allow the driver to use more of the gears in the transmission without dropping out of the power band. It does mean more shifting, but in a modern car, that is basically a non-issue (increasing the number of shifts per lap can slow you down in older cars, but in newer cars the shift happens so fast you barely lose any speed)
- high power, low grip. This is where transmission flipping got it’s start, primarily in the drag racing scene. If youve ever driven a high power car on low grip tires in a GT game, you’ll know that 1st, 2nd, and 3rd are basically useless, as they’re just pure wheelspin. The basic goal of a transmission flip in this scenario is to make 1st and 2nd as loooong as possible, so they can actually be used, while maintaining good acceleration in 4th, 5th, and 6th Gear.
Transmission flipping is not some magic button that instantly adds speed. It’s simply a way of using the tools available to make transmission tunes suited to specific kinds of cars. When it comes to making custom transmissions, knowing how to read the torque curve is more important than knowing how to flip a transmission.
