We want the trigger button to up shift, and the thumb button to downshift. Our problem is that the transmission only switches gear when the trigger or thumb button are depressed. We want it so that when a trigger or thumb button is hit, it shifts gear and you do not have to hold the button down. Is there anyway to fix this. Any help would be appreciated.

I almost always have my switches work via edges not via states.
For example rather than:
If (switch==1) then PWMout = XXX else PWMout = YYY
I do this:
If (switchNow==1 and switchOld==0) then PWMout=XXX
Elseif (switchNow==0 and switchOld==1) then PWMout=YYY
The second case allows you to have other conditions change the state of the PWMout.
If you do things this way, what you want to do becomes trivial:
If (switchNow==1 and switchOld==0 and PWMout=XXX) then PWMout=YYY
Elseif (switchNow==1 and switchOld==0 and PWMout=YYY) then PWMout= XXX
The above pseudo code will allow you to use your switch to toggle between XXX & YYY states.
There are probably better ways to do this but I hope this will give you some idea of how it can be done.
