GA6HP19Z e90 2006 transmission problem after Reset Adaptation.

[E90 learner 2]

So, my car has a jolt and hard shift after changing transmission oil. After a year, I check the net and youtube, they fix it when resseting the adaptation. 
I tried to reset the adaptation and car went smooth acceleration is ok and stuff. But after a month, car will jolt as if somebody bump to you at the back. Sometimes, when during traffic stop (Traffic light is red), it jolt like somebody bump you. If you do nothing, it gets very worst. From just during hard brake, it will not jolt from acceleration from 2nd to 3rd gear and from 3rd to 2nd gear. 

If you reset it again, It will come back to smooth again. Then after a month or more it will go back to it. It will happen fast if you are driving the car like 30 minutes or more.

I was thinking disabling the NIC (Neutral Idle Control)? Or need to check my fluid level? I remember when changing my radiator, the mechanic also remove the small radiator which is connected to the radiator. Maybe it is no longer optimum?

Thanks.
