First step is to scan for codes. Engine sensor problems can cause unusual trans shifting.
Also unclear what you are saying - e.g. no idea what "bangs first" means.
Are you mostly saying that it upshifts to 3rd prematurely? At what RPM is it making each shift?

Does this happen under normal driving. ie anything under WOT will it act normally?

What happens when you put it in manual 2? will it hold 2nd as long as you manually select it?

The more information you give us here the more educated response we can make.

what i think you're saying so far is, under WOT, 1-2 shift happens as it should and feels solid like it should, but it shifts out of 2nd very soon after the 1-2 shift is made. correct?

You know I never tried to put it in 2nd and see how it drove. It only happens when I punch it if I'm driving normally it'll shift at low RPMS as it should every gear. But when I put some power into it the car will shift very hard... A friend told me that there is a shift kit in the car which could be why it shifts like but still trying to understand why when I punch it it'll rev out 1st year go into 2nd for like 2 seconds then shift to third.

What do you mean by WOT?

WOT is "wide open throttle" meaning when you have the pedal to the floor.

If it drives properly under normal throttle, how does it respond when "manually" shifting under WOT?

If you start in manual 1st from a stop giving it plenty of power, then shift from 1-2, will it carry the gear all the way until shifting into third? or will it "fall out" of 2nd
