When you upgrade a standard transmission to the Dog Clutch trannie, can you still use the H-Shifter and clutch pedal on the G27? I don't know much about Dog Clutch transmissions, so it might just be me. Is this a glitch or anything?
 
A dog box has no Synchromesh, and is works best with very fast gear changes, and designed to work with rev matched gear changes, so clutch is not needed as such, the clutch will still work the same as with a normal gearbox, and will still be needed for standing starts
 
So far I've been seeing inconsistencies with the adjustable transmission--all of which include the "dog clutch."

I'm finding that when I upgrade most cars to this, it disables the H-pattern shifter (gear changes won't register), but not all. You can only use the paddles or a sequential stick (if you have one).

I also bought the NOMAD Diablo, it ONLY comes with the adjustable/dog clutch setup, and the H-pattern works.

However, I bought the Sauber C9, again it ONLY comes with that, and the H-Pattern won't work. I've researched the C9, and it's supposed to have a 5-Speed Manual transmission, not sequential.

The Mazda 787B is my next "big" planned purchase, and I will be very disappointed if the H-pattern doesn't work with that car in Gran Turismo 6. I know for certain that the real car features a 5-speed manual.
 
DBM has it right. Dogbox is meant to be straight shifted, or double clutched. Straight shift is a clutchless rev matched shift, double clutching is just as it sounds a double clutch bump as you move the shifter in / out of gear. Commercial trucks use this type of transmission for a number of reasons mainly faster shifts, less clutch wear and tear, and less clutch leg fatigue.
 
All Modern Race Gearboxes and adjustable Gearboxes will be sequential shift. also most will have straight cut gear, and hence be noisier, (straight cut give less drag).
Older classic car may have had adjustable 5 or 6 speed H pattern gearboxes.

I'm not sure why they game can't let you have the option of Adjustable 4,5 or 6 speed gearboxes for all cars though. ( I know for a fact you you fit a sequential 6 speed IRL to the early TVR's, but you only get a adjustable 5 speed in the game.)
Also let you but just an adjustable diff (final gear), and let you use stock gearbox.
Also let you use H shift if you wish.
Plus have a option for straight cut (so you remove gearbox wine)

More importantly, the angle of the cut is a compromise between noise and strength.

Any racing gearbox will settle for more noise in order to handle more power.
 
I've noticed that all the cars modeled with an automatic transmission (ie: 67' El Camino, 11' SRT8 Charger and 08' Challenger, plus many more) make you use the paddles or sequential shifters when you upgrade the transmissions. What I don't get is why you can use the H pattern when driving with the stock transmission, the driver is animated to reach down like he's shifting but in most cases there's nothing there.

I see why they did this for the automatic modeled cars, but you shouldn't be able to shift the car at all, let alone with the H pattern if the car is an automatic. It's too inconsistent and they either need to make it so you can't shift those cars unless you upgrade the transmission, or let us use our H pattern.
 
I just drove the Mazda 787B in the first mission in the S-Class category. It allows you to shift the car with the H-pattern and clutch. Assuming it will be the same when I purchase the car, and it only comes with the one transmission option (adjustable/dog-clutch), then this is realistic, whereas the Sauber C9 isn't with sequential shifting only.

So yes, it's inconsistent, because upgrading muscle cars to an adjustable transmission and having it disable the H-Pattern is ridiculous. Once again, Kazunori and Polyphony Digital cease to amaze me with how "out of touch" they are since GT5 Prologue was released.

Here's an in-cockpit video of the Sauber C9. Looks like a full manual to me. He's operating the clutch and the stick is multi-positional (not a single spring-loaded sequential lever). I guess if I want to really enjoy the C9, I just need to go back to Forza Motosport 4 where the stick and clutch work (and REALLY well, unlike GT5's horrible clutch operation), and the sound is incredible (and doesn't sound like a vacuum cleaner as it does in GT5-6)



Watching him downshift, it reminds me of how horrible the clutch is in GT6. That's really how you should be driving for better car control. It keeps the Rev's up and avoids differential drag or lock. However in GT5-6, when you can use the clutch, it is so terrible, it often won't register most of the downshifts (if you're shifting as if it's a real car). By the time it gets it, the engine revs have dropped, and you often lock up the differential and the car spins around.

After spending more than a week in only GT6, I went back to Forza Motorsport 4 to compete in an online series race yesterday. The new tracks in GT6 are great, but Forza 4 is still soooo much better in many ways, even if it's "upsampled" from 720p resolution. I'm just not feeling any real "love affair" with GT6, as it's pretty much the same "grind" as GT5 was with several flaws and problems (with apparent new ones, such as this inconsistent transmission problem).

Maybe with all the promised updates that are coming, they actually will "fix" many of these problems... some of which carried over from GT5. Considering the six-year development of GT5, it launched with major omissions and problems, and still not everything was fixed the couple of years it was out, I'm just not too hopeful. I was a fan of Gran Turismo, but today they are falling way behind in many ways.

BTW, I completed GT5 (100%, 1,020 cars) and have reached level 319 in Forza 4 (500 cars-maxed garage), so I have quite a bit to go on to make these evaluations.

Well, Just found out that the 70 Dodge Charger is forced Sequential too... I can tell you that owning a 70 Charger, that this is not the case... I can see some of the newer cars, ok fine... BUT with the Classics and Muscle cars, why?... I've been playin' GT since day 1, and always been a devoted fan... I'm just not understanding the reasoning behind this...
