SRS light is not related to your transmission problem.
If the car bangs when you put it in gear it could be two things.
First the valve body in the transmission.
Second it could be a motor mount.
Do you have the check engine light on?
Does the car shift normally in other gears?

Hello and Thanks for your response.
I didn’t mention that SRS light was related to transmission problems in fact the car has SRS error on its instrument cluster and in the meantime the transmission has some problems.My car doesn’t make any noice as I put it to D position instead as soon as I press the gas pedal (on D position,car stationary )the car shifts very badly without making any noise and also engine check light is on.
The car shifts normally in other gears
It could be a bad motor mount. Do you feed vibrations on your steering wheel or seat when you are stooped at a light?
No there are no such symptoms.the only thing felt is after pressing gas pedal.as I said before,as I press the throttle,it changes gear very badly and not smoothly(only very first gear)I mean from 2nd to 1st maybe Cos I heard,if true,this car starts from 2nd gear.
Mostly this happens when I take off from a light and it shifts hard one two and the rest firmer and normal.

Press the button that puts the transmission in winter mode. In this mode it always starts from second.
It is the S/W button or may also say C/W.
If it doesn't give you the same problems in W, there is an issue with the first gear. Solenoids or band for that gear can be bad.
