Jerk when idle in D
 

2018 Elgrand makes one jerk each time when completely stopped and gear position in D. The jerk forward motion comes after approximately 10-30 seconds from complete stop and feels like the someone from behind hit my car. I've changed the CVT fluid (NS3) and both filters but the problem is not solved. Anyone can share similar experience and solution? Thanks!

The transmission model shall be JF011E RE0F10B
