Difference between F1, DuoSelect and MC Shift gearboxes ?

[Harvey_Tim]

My QPV Sport GT S has a ZF gearbox so the answer is actually irrelevant to me but I am asking this question just because I am interested to know … so what are the differences between F1, DuoSelect and MC Shift gearboxes are they just revisions / evolution of the same thing or are there fundamental differences between them ?

Thanks,
Tim

F1 = Duoselect (which is what it was banded in the QP) = clutched manual gearbox (Graziano in the 4200, not sure in the GT / QP) with computer controlled clutch and gear changes.

I think the MC *shift* was a variant of the ZFHP26 with new software (so a torque converter autobox)

This electro-actuated gearbox can change gears in as little as 100 milliseconds – faster than any driver could achieve with a conventional manual tran

Interesting, thank you. So the MC Shift does use a clutch, does it suffer the same premature wear as the F1 and DuoSelect systems?

Everyone drives differently but you're best to keep it out of Auto mode unless it's the ZF box.
Parking is one of the biggest F1 clutch killers especially if you are parking on an incline.

I think 30-40k can be expected from a clutch but it’s driver and driving condition dependent.

Confusingly, the early robotised manual GranTurismo cars were called MC Shift. But at the time of the final face-lift versions, they used this terminology on the automatic gearbox cars if they had flappy paddles fitted. Well, I think it was something like that. Best check with Dicky Grace. Oh - I think that was MC Auto Shift actually.

But in essence, in cars up to about 2015, phrases like F1, Cambio-Corse, Duo-Select and MC Shift basically meant the same, i.e. a robotised manual gearbox. Naturally it improved as the years went by, with ever quicker and smoother changes.
So if a Maserati QP or GT from about 2005 to 2015 has a gear stick, it's an auto. But if it has no gear stick, and has flappy paddles, it's a robotised manual.

The 6-spd transaxle is pretty much the same architecture throughout 2005-2016. Where there are major differences is in the clutch area - as power/torque rose, the clutches were beefed up, the release bearing got stronger/better too, software was vastly improved. Also there were changes in the actuator which changes gears on the driver’s behalf - it was revised several times to make changes as fast as physically possible - MC Stradale/599GTO are down to 60msec!

They are all F1 gearboxes but in various evolutions .
