So what gearbox is it with the T-jet engine or the other engines?

The list I've found is:

5-speed: C510 (used by the 1.3 Multijet)
6-speed: C635 (used by the 1.4, 1.4 Tjet and 1.6 Multijet)
6-speed dual-clutch: C635 (used by the 1.6 Multijet)
6-speed automatic: Aisin AW60T (used by the 1.6 E.torQ)

I'm not sure if it's accurate, so if anyone can correct me, please do

OK

So which one is better then, I guess they are both better than M32.... I hope.
