There was a problem of jerking on shifting from 2nd to 3rd gear on speed of 30km/h on light foot. It was ok if we push the throttle more like higher rpm.
That’s a big relief to get it fixed by changing the transmission oil and filter. The shift is so smooth now.
Thanks to all for being very helpful & rapid replies.
