We got a charade with 5efe with automatic transmission. Working perfectly with no major issue... If your brother want to have an auto tranny, go for it. But you need to make a new mounting at the lower right side (For Manual tranny, you have used the default/actual mounting/brackets) but for auto, the location needs to be changed. Secondly, you need to make a hole in the body for the auto transmission Lever cable. Auto transmission assembly is heavier and bigger in size as compared to manual one.
