2006 Mazda 3

Transmission problem
2006 Mazda 3 4 cyl Front Wheel Drive Automatic 40000K miles

I got into an accident, and my car has been in a garage for 1 month. Turned it on this morning for the first time. AT, CHECK ENGINE LIGHTS are on.

-fluid leaked from a hose in the front. Its transmisson fluid.
-the car reacts slightly when I press the gas
- it hesitates and backfires and rpm is always at 2k and wont pass 3k.-
-wont accelerate and no manual mode.
-there is al box connected to the air intake it seems to have been chipped, if I move it the car revvs.

1) what type of tranny fluid does it take ( I refilled it with ATF III made by Shell li, fixed the hose, light is still on)?
2) should I change the box connected to the intake?
3) why isnt reacting to the gas pedal
