Pajero iO 99 4G93 A/T jerks on 1st to 2nd gear if leaving at idle

Greetings forum friends.
I own a Pajero iO 1999 4G93 H76W automatic transmission.
I noticed that when going from 1st to 2nd gear, leaving at idle, the car jerks. If I step off the accelerator, he's fine.
This only happens from 1st to 2nd gear if it goes out slowly. I feel this effect more in traffic, at traffic lights, etc.
I changed the transmission oil, coils, spark plugs, rear lower arm suspension bushings, transmission support bushing, and the problem persists.

Has anyone gone through this?

In advance, thank you very much!

Note: Apart from this defect, the car shifts smoothly.
