Thanks for your reply ryzno, I just came in about to bump the thread then i realized your post was much longer than before.
I get how its suppose to work, theory wise. My question is, Does it actually work in the game? And what steps do I do to achieve this, in the game.
Yes it does. The problem will be adjusting your top speed with the final gear.(I have seen a lot of racing tunes that say, use final to adjust top speed to track) The way we have or trans setup, there is little adjustment except to tweak each individual gear. So every time you go to a new track you'll have to do it all over again.
With that being said, when you go to flip your trans, you will have to figure out a final to flip it at so when you move the final to 2.5-3 the top speed will be the top speed you need to achieve at the end of the strait.
Example(random numbers for example) Ok say you need to hit 210MPH. What you would do is move the top speed all the way left to (usually 112MPH) After that you would set the final to a number that should get you to the top speed you need when your done. So I'll say set final to 5.00, you would then move the top speed slider to the right then the left
1 TIME. After that you would then move the final to its lowest setting, hopefully giving you the top speed that you want. You can then adjust each gear to your liking(obviously adjusting 6th or whatever last gear will effect top speed)
Some of my confusion is coming from people saying final gear all the way to the left = more acceleration (pull to be exact)
But the post I linked in the OP says the opposite. So... whats what?
Like I said it doesn't really "create" more torque, you are just making the drivetrain more efficient. All we are doing is making a close ratio trans, that's adjustable and has a efficiant final drive.
The 4:1 ratio would have more torque than the 3:1 ratio right?
which way is which in the game?
I'll explain this one more time
This is hard to explain I had to sit in a 3 month transmission class to understand this. And it could honestly take me that long to explain it

I actually had to bust out my school books for this.
First off, a gear ratio multiplies or divides the amount of effort that the motor exerts powering the driver gear. So say the engine puts out 100lbft of torque.
if you have a ratio of 4:1 the driver gear will turn 4 times to turn the driven gear 1 time meaning only 25lbft of tq are reaching the wheels. Now if you take the same engine and put it on a 1:4 ratio the driver gear will turn 1 time turning the driven gear 4 times creating 400lbft of tq. And obviously a 1:1 would only produce 100lbft of tq.
So as far as a final gear is concerned the closer you can get it to 1:1 the less power you are losing.
And yes it seems like 4:1 has a better pull, that is because the drivetrain is under less effort to turn everything. Like I said the final gear is
reducing the power coming from the trans to the wheels.
So try to set your final as low as possible. Also I cant guarantee that you will be able to achive 250+MPH with our setup.
Also dont wrap your head around this. IRL you can change the final all day and never have to touch the trans. But GT has it setup so changing the final affects how you flip a trans. Also IRL you are stuck with the ratio combinations that are available. Not a unlimited number of ratios that you manipulate to your fancy.
lol.. i'm confusing myself at this point.

your starting to confuse me too!!! I hope this helps.
@YN89 There is no over thinking transmissions, I have a 400 page book explaining them. And another book that's 1600 pages explaining Everything from hydraulic principles in a brakes system to how R134a changes in a A/C system, I an go on all day dude.
PS: These are physics theories. And also to any dragsters that want to hate me for giving out our trans trick, go right ahead, its all over the place anyways
