I've been searching around and I found this on Wiki. linkKia Forte

They mention there is 5-Speed Auto Transmission(AT) while in Malaysian version Forte just only have 4-Speed AT. The 5-Speed AT should be more fuel friendly than the 4Speed AT.

My question is:
1. Can we have them(Naza) installed the 5-Speed AT?

2. If no, can we change it or do something to get the 5-Speed AT?
