the tranny flip is what enables people to exploit the physics and get unrealistic amounts of grip, making their tyre turn orange and staying orange without scrubbing any speed.. and then their cars handle like shopping karts and they cry when they wreck themselves tring to block you.. **** those people
You have been lied to, deceived, or fooled.

I meant more in the sense of the gear clusters themselves; in "adjustable" boxes you're usually working with a gear set having specific tooth pitch and tooth counts, giving only a limited range of ratios that bridge the gap between the two shafts in the 'box. Of course, you can machine whatever you want, but that's also extreme.

So it's sort-of unrealistic to have that level of precision, but I think it's far more unrealistic to impose limits on the range, especially when the limits can be bypassed by other means.


That said, a separate final drive part would be very useful indeed, giving longer / shorter gearing without all that tranny whine (and losing H-pattern in some cases), for starters.

An additional development might be specific gearboxes (and a wider range of / option for gearbox types) with gear sets selectable by tooth counts as much as ratio, but that's a nightmare waiting to happen.


With PD's data input accuracy, it's likely better we get the fine adjustment all around, for the necessary "replicas"; but they could separate the final drive out all the same and offer e.g. adjustable H-patterns separately from the sequentials.
All I have to add is proper automatics. :) (Like the Merc SL55)
 
Theory from foxden_racing from /r/granturismo:

Jury's out, as far as I'm concerned.

What does strike me as obvious is that something in tuned transmissions is failing the anti-modding protection. Pretty sure I read somewhere that GT validates your car against the on-disc version, and if it's invalid resets what's out of spec.

Whether it's intentional or not, I can't say. It could be: if flipping the transmission allows for gear ratios outside the valid range, then they've closed a loophole. If flipping doesn't allow things outside the range, then they managed to break something.

...

If what I read is correct, GT6 protects against "hacked" cars by validating against its known-good source [the master DB], and if it finds something out of place it resets that aspect of the car. Cheat protection is far from perfect...time trials were ruined for months because it wasn't looking at the RPM ranges, so guys were cheating by having F1 cars that turned 30 or even 40,000 RPM, and the engine power code extrapolated what it should be making at those ranges.

If flipping the transmission allows you to go outside those known-good ranges, and it's something cheat protection watches, the minute you try to drive the car it'd trip the anti-cheat mechanism and reset the transmission's settings.

If it's intentional, then someone at PDI has discovered the 'flip a transmission' trick and closed that little loophole.

If it's not intentional, then whatever they did while setting up the new VGTs had the same effect.

I only use the auto-set sliders anyway. ;)
 
So you want to make the stock gearbox with a customizable transmission? I just turned off the game so I'm going to have to look at that tomorrow. I noticed that 1st and 2nd were pretty close though so it's possible that it can't be done with the customizable box. With or without flipping.

You should check what I link. The page says it's the S7, not the S7 TT. The data may still be wrong though, but according to the site it's for the S7.

And yes, those gears can be reached. I just did it. Try it yourself. #noflipping

If somebody can replicate factory gearing with a custom transmission,(without "flipping") I'm all eyes.
I'd certainly love to see Saleen S7 gearing replicated in any fashion at all.

If you can't replicate factory gearing, that's the definition of unrealistic, isn't it?

But since the update, the only transmission that could be used from your Replica Tune is the 2nd transmission. The 1st and 3rd transmissions that you list, you need to move the Final Gear a second time, after setting the individual gears. That means the gearing will revert back to default when I get on the track. :mad:

:banghead: So there's no way to do it :irked: Have you tried all top speed value gear range after setting the final 1st time ?
 
Jeez, what a mood-killer. Here I was, all amped up at getting a day off to update and run the seasonals, and now every car in my garage (With the exception of all but a few of PD's "Precious" VGT's) will be completely 🤬 up the moment I try to drive them... Especially when the "Flipped" transmission is worth up to 1-2.5 seconds a lap depending on the car.
 
:banghead: So there's no way to do it :irked: Have you tried all top speed value gear range after setting the final 1st time ?
No. I have not tried all the different top speed settings. I'm hoping that PD releases a hot fix and we go back to the way it was, pre 1.17 update. However, if several days go by and there is no mention of a fix coming I will have no choice but to try and find a work around. For now, I am only driving cars with transmissions that won't be impacted. This is a real bummer.

Just because it seems a bit too structured to be a bug. For instance, when you went online and changed cars and no one but you saw that car..that's definitely not intended behaviour.

This seems intentional rather than something that broke. Now, I know many many have noticed that trying to tune a transmission online can be PAINFUL because of how slow the process is. It's been a slow process overall since GT6 launched, so something more is happening int he background. It might be a necessary evil to fix some other issue.

I'm not denying that the transmission tuning has worked a particular way for 15 years. There was something similar to this in GT5 when people were modding transmissions. Maybe they've found some data that shows this type of tuning breaks something else in the game.

In any event, I think this is what others are feeling. That this seems to intentional to be a straight up bug.
WHY? do the gears revert to some wonky position, NOT DEFAULT!!!!! Only the speed slider and final drive revert to default the numbered gears go to far left which is not the default position.

Also when I sent GT a message on facebook this was their reply:
Hi, we are aware of this issue and the team is working on a fix asap

 
In the dozen or so cars I have tried it is not just the final drive but every gear. I have changed one gear only left car settings gone back and it has reset, no race needs to be entered, just exiting the settings seems to be resetting to default.
I haven't experienced that myself. It seems there are some strange occurences with this gearbox bug

Well, this was already answered, but I will mention that after some fooling last night, I did find that more transmissions of real life can be replicated in GT6, (without the flip) than previous titles, I don't know if that's coincidence, intentional, or if PD increased the available range of gearing.
I know I can't use my Cavalier/Sunfire 5-speed transmission replica in the Sunfire GXP concept anymore for sure. :(

no ive been knowing how physics works
You can do better than that, right?
 
Not sure if this is part of what is happening, but after setting gears if I put any engine stage upgrade on, the top gear whether 5th, 6th etc goes to reset, only that gear, probably been there all along but have only just noticed it due to the current problems.

Is the actual number changing or just the slider position?
If it's just the slider that's normal when you add RPM, as the game add's gear range to each gear, you're just noticing cause i'm guessing 5th and 6th where all the way right.

.

A good point didn't think of that, checked and the number changes and not the slider. I also never have top gear all the way right.
The effect while driving is like missing a gear, for example going from 3rd to 5th

Yeh the more we dig the more this is showing to be a bug and not intentional. Gear ratios chanign when you add power parts should not be happening.

CAN I USE BOLD CAPS TOO??????? LOOK AT ME SCREAM ON THE FORUM!!!

Your post is the first I've read of "some wonky position". I haven't had it happen to any of my cars yet and I don't plan on going to look for it, but from this thread it sure sounds like there is some adjustment happening to match the gears to the final drive. Am I wrong in reading that?

It has always done so. But that's only because of the changes in the rev range that these parts add, and it's only the engine parts in the left column that will cause any change, the engine parts on the right do not have any effect on the numbers/sliders.

You are correct I read his post wrong. only half awake. -_-
@SJC ALPHA if the slider is not moving then it's normal, I bet if you check all the gear numbers are changing and the only reason it seems to only affect 5th and 6th is because of their placement in the gear range.
 
What I want to know is was this done on purpose or was this a mistake by PD? Since all we get from PD is crickets chirping we have to guess. If this is permanent tell us so we can move forward with transmission tuning. If it's a mistake tell us a fix is on the way to keep people from jumping off the cliff. Personally this is the straw that broke this camels back. I was thinking about PC gaming, now I am doing research and will make the jump soon. A PS4 is now not in my future. This update and no word from Sony or PD has sealed that deal.

I kinda think it's intentional. How would one accidentally fiddle with the transmission tuning, as a programmer?

I think it either doesn't work as intended, or PD didn't think of the consequences, like the fact that adjusting final gear from track to track is pretty easygoing normal concept that people don't want removed. The only reason someone would want it removed I can think of, would be because they don't feel like tuning themselves.

I'd rather not, call me skeptical. :)

Actually, my drift SLS AMG got a value for 4'th gear of 9.999, then when driving, top speed in 5'th was about 150kmh, and top speed in 6'th was, well, at 300kmh there was still a long way to go to redline. Thats wonky for you.

I have no idea what you're trying to say here. "Your think bubbles"? Huh? And Vette's dummy split?

You posted like 4 or 5 times now, and haven't really said anything actually.
The closest thing was telling someone to use grammar. The rest is horse manure bro. What gives?

Known Issue Regarding the Transmission After Update 1.17

From the link :

"Known Issue Regarding the Transmission After Update 1.17

After the installation of Update 1.17 for Gran Turismo 6, an issue has been found wherein the parameters set in the [Fully Customisable Transmission] would revert to the default values.

Steps to reproduce
(1) From the Quick Menu screen appearing before a race or from the [Garage], go to [Car Settings] and select [Drivetrain (Transmission)];
(2) With the [Fully Customisable Transmission] purchased and installed, change the [Final Gear] parameter from the default value to any value;
(3) Upon starting a race, the parameter set in the [Fully Customisable Transmission] reverts to its default value.

Please note that if the value of gears other than the [Final Gear] are changed, this issue does not occur.

We will publish a further notice once we have completed working on the fix to address this issue. We deeply apologise for any inconvenience this may cause to you."
