Transmission Shift

[hata]

Hello first post from Thailand

I have some problem about transmission shift

Transmission shift 1st to 2 nd..3rd...4th smoothly when engine cool but when engine hot(operate temperature) transmission seem shift from 1st to 2nd like 2 step, also from 2nd to 3rd and 4th but mostly feeling on 1st to 2nd.

Any suggestion to check or replace any sensor?

Thanks!

what year is your RX? Is your RX AWD or FWD?

First things first - check your transmission fluid level....
