Woah there Nelly, before you go ripping your DFGT to bits (not that I'm questioning your technical abillities) but what gear shift method do you use? If you use the buttons on the back of the wheel as I do, then re-assign the shift stick on the right as pull for handbrake, I also set it to push for reverse rather than trying to press a button on the wheel and steer at the same time when reversing.
What ever you decide best of luck, just thought I might be able to save you some hassle.
