Bro, new vitz auto trans is CVT, like city vario, but no dipstick, u can check its fluid by a small nut front at trans, if cars mileage is above than 50000km than should replace fluid with toyota genuine CVT, others not, but its replacement is bit tricky, 1st drain all oil from chamber's nut in clean container then measure it, then open its chamber clean filter & chamber with petrol, dry then tighten with red silicon, all these should be done by expert mechanic, fill CVT fluid exect amount that was you measure cause there's no dipstick in it, some mechanic fill over fluid and check filling hole by finger tip thats not true, it will harms transmission if you live Punjab society near dha, a gud mechanic Mr.Nadeem at main punjab society road, work shop named Madina Auto or Cherry auto behind Shell pump main market cross nishat colony.
