Problem when switching to the next gear of my Civic'10 (Automatic)

[StockEngine]

Bali, from 0 -15kph wala pong issue, pag nag 16kph na saka po xa parang feeling na naka manual ako na nag s0hift, parang may delay po pag dating ng 16kph then going more than 16kph wala naman na. Basta po, hindi talaga nag xa nag sskip sa 16kph kahit tuloy ang apak ko ng gas.. Dadaan at daan xa sa 16kph then dun ko ramdam ung malakas na shifting going up (Car is an AT). Di ko po kasi na test drive ngayon eh, may bagyo

Bali eto po yung gamit kong oil, for my Civic FD. Okay po ba yung oil na yan?

The oil is fine. You dont need to use honda. We have a seller here that sells a package for your honda.

As you mentioned it happened way back, its probably an electronic part. Dirt got dislodged so its running normal again.
