Complete gearbox of ALTO vxr is not available in market. If somehow you find it, they ask too much for that like 30 - 40K
Qabli japani ALTO's gear is same but gearbox (tapay) are different so doesn't fit into local ALTO.
Solution is to get and install qabli gear's internal mechanism into your old gearbox.
It costed me 11K for gear + 2500 labor
