If I am correct, the F Sport edition of the NX comes with rev matching. It is awesome when it seems to finally "warm up". The downshifts get a little blip in RPM's to make for a smother downshift and the upshifts seem to be more instantaneous. It seems like it takes a while for this feature to kick in though. When I first start out, the downshifts and upshifts and more gradual like downshifting in a normal car. Does anyone know how this works and how to get the rev matching right out of the gate?

 

I echo your observations on how the transmission works. The IS and past RX F-Sport behave in a similar fashion where the gear shifts more quickly when it hits its internal optimal operating temperature (midpoint on the engine temp gauge). In addition, you are able to manually shift sooner (if you choose) from this point onward.

 

I noticed the rev-matching only works when your drive stick is in the M position. If you use the paddle shifters while the stick is in D, the downshifts work like a normal gearbox.

 

Interesting.
