Gearbox setting on PC

Dear friends!

I bought a steering wheel t150 by Thrustmaster, but without transmissions. And I’ve got so problem. If we in the Settings of the Forza 4 choose manual transmissions, then we have to change each speed using petals on the steering wheel. But It’s uncomfortable for me, because It’s my first steering wheel, and I can’t change speeds quickly. But if we choose automatic transmissions, then the brake pedal is recognized as reverse gear, and car go rearwards. Can I tune the Settings for so combination as recognition the break pedal as stop, automatic transmissions and using rudder petals for changing forward, neutral and reverse gear only? I know that so setting combination is in Euro track simulator 2. Has Forza 4 the combination?
