That fuse is still fine I already checked it I left it open when I put the new one in and turned the climate control defrost on and watched the fuse to make sure it didn't blow again. The fuse is just fine.

The kick down is activated by a switch under the accelerator pedal. The floor mats or carpet can keep the pedal from pressing it down. If it is being pressed and you have no kick down, I would suspect the electrics and that leads back to the fuse. Out the volt meter on it and see if it is still working. If it is, then you might have a wiring issue.

Another possibility could bee a seized auxiliary water pump. This is located near the monovalve and runs to circulate hot coolant through the heater core when you are at idle. If it goes bad, it could draw enough power through the CCU to burn it out. Since you did not see any burned traces when you had it apart I do not think this is the case.

When you push the CCU buttons do the pods cycle? You should be able to hear them opening and closing the flappers. If they do not cycle then I think you are not getting any power to the CCU. That is the black/red wire on pin 13 on connector X1
