For me the jerking only happens when upshifting from 2nd to 3rd gear or from 3rd gear to 2nd gear. other than that no jerking.
EDIT : One thing i need to add is it happens only when the foot is not on the accelerator. E.g. When i m cornering, i let go of the accelerator, when the car slows down i feel the jerk. But during exiting toll, i step on the accelerator from 0 - 80km/h, i don't feel the jerk.
The jerking feels like gear shifting but i don't think its becoz its not CVT engine. Even my wira or proton saga blm last time don't have this kind of jerking/pulling feel. You can feel downshift in a smooth drag feeling (once) but with forte it's like (dek dek dek, 3 times jerk). I asked SC during 1K service and they said it's normal, even took my car for a drive and still they said no problem. So i m not sure if it's pulley problem.
The undercarriage sound is more substantial. I can hear it everytime i off the engine. Last time wira and proton don't have this sound. But the toyota startlet turbo i drove last time got. It's from the exhaust cooling down. Quite loud, but i think should be ok

i got the same thing happened as well but i think i got no problem with that ler, seems more like pulling than jerking for me hehe

ok, my guess... why you have this jerking..
when you downshift your gear.. u do not step on the acc. pedal, right?
and during the moment your downshift and you "immediate" step on the acc. pedal and then you got the "jerking" moment.
try again when u downshift, put a light foot on the acc. pedal and downshift see whether u have the jerking or not.
yeah... seems normal as it happened to my car also, more like pulling instead of jerking
