Transmission slip

[Bill Mak]

Hi. 2004 RX330 when coasting to a stop, but not completely stopping, applying throttle causes a slight slip in he transmission almost like it goes into too low of a gear. Has been doing this since I got the car over 100k miles. Hasn’t gotten any worse, just annoying when accelerating from a very slow roll! Fluid ok, no warning lights or codes, no other shifting problem. I heard something about a “firmware” update but figured I’d consult the forum first! Thanks.
