Hey Team,

2021 Lexus RX350 - F-sport.

As some have said, we need a setting between "Normal" and "Sport"

Normal upshifts way too quick, jumps to gear 4 and 5, then shifts back down, then back up - what a mess, how did Lexus let this go?

Sport is great, but in the 50-65 MPH it holds the RPM way too high, no one needs to be at almost 3K RPM when cruising at 55 MPH.

Short of driving the car with manual gear switching, is there ANY solution to reprogram the transmission shift points?

So many mods, upgrades, etc. in the car world. This has to be do-able. Any ideas?

I don't know if you have seen this...

There is no fix, it's perfectly normal, lol

I have had three of them one was so bad I sold the car, the next was ok, on to the third, and it is actually good. All F sport's

I think the tranny tcu and the main ecu have no clue what's going on, nor does Lexus. But I did buy two more after the first one....
I just took a break for a few years and drove a smooth as butter GMC !!! wierd

The TSB is also useless, at least for the older 2016-2018...
