After buying a vezel 2017 hybrid few days back My findings about its transmission in Vezel Hybrid:-
It is 7 Speed DCT (dual clutch transmission)
Oil Type: ATF DW1 ULTRA Made in Japan only availabale at Honda showroom pic attached. Do not use commonly available plastic bottle oil in the market. It is not ULTRA.
Oil quantity: When you drain it out via bottom plug then 2 litres. if it is sucked out by machine from top then 1.3 litres.
Never put 3 litres which is common practice outside in market mistri khanas. You will damage your tranmission. I almost ruined mine when mistri saab put 3 litres in it.
Change every 20000 to be on the safe side. There is a metal filter which comes out with the bottom drain plug. Dont forget to clean it.
