this is awesome work bro!

I managed  to fix the shift problem with 18 wheeler by doing ascript checking the state of my controller (have a spring returned shifter)
Here it is, joy button 15/16 is the shifters two states and 'v' triggers the in game shifter

 

3joy16::
Send {v down} ; this holds the v key down
KeyWait, 3joy16 ; waits for you to release H
KeyWait, 3joy15, D ; waits for you to press Down L again
Send {v up}
KeyWait, 3joy15 ; waits for you to release L
return
