Toyota C160 Reverse Gear Problem

[Parmas]

I have a problem with my C160 regarding the Reverse gear.

Since 6 months ago, (which was the last day I drove the car) it was working. At that time I had a problem of the gears 2 / 4 / 6 not entering from the shifter. The problem was the shift cable overheated.

Since I had new cables and a Quick Shift of the AE111, I decided to fit them into my yaris. The cables were about the same length no problem but the shifter needed to be cut and plastic welded to match the gear positions. I got all 6 gears working fine but oopss the reverse is not entering at all!

I disconnected the cables and tried directly from the transmission but I can't seem to make it gear. I am trying to gear it by pulling to the end the shift arm and gear it to the left. The strange thing is that if I pull as much as it lets me, it gears 1st instead of reverse (which has to be the higher upper gear).

Any suggestion what I can check before removing the transmission itself? Which I preferably not want to !
