Sorry for the delayed response. If you can't get the shifter out or you forgot to remove it when you tried to lift the housing up all is not lost. It does however mean that when you lift the housing up all the gears will come with it. You will need to tap on the input shaft with a soft faced hammer. Plastic hammer works best. stay away from brass or bronze. Alternately you can hit on a piece of wood with a regular hammer with the wood between the hammer and input shaft. Once the upper half with all the gears is seperated from the lower half tap on the two shafts from the other end where 5th gear was. If you already removed 5th gears and the retainer plate and large bearing snap rings the shafts should fall out of the upper housing and this should free up the shifter to be removed. Good luck.

You will need to be a little more specific. What type of help do you need? Please be specific and if I can help I will.

Hopefully you made a note where each one goes. if not look at the spring size and the detent cut out on the shift rod to see if you can determine where the larger or smaller detent balls are located. I'm a little surprised for a Toyota C series transaxle. Most of the ones I have taken apart have all been the same size.
