just take out the shift fork and input bearing, then take the bell housing off by removing the bolts that bolt it to the tranny box it'self, then there might be another plate you need to take off idk, if theres not you should be able to see inside it but your going to have to slide everything out. Most of the gears in a manual tranny are pressed in so dont try and pry at them. i have never opend a ka tranny but i've been in a couple other rwd manual trannys and they have all ben the same. oh ya drain the fluid
