Car hangs on first gear??
Every couple of days i notice the RDX hangs on a low gear, i believe the first gear, while in regular drive. If im going 20-30 MPH my foot is static on the pedal, giving it some gas but not progressively pushing harder, the RPMs will continue to go up and the engine will get louder but it wont shift until i give it more gas and push down harder on the pedal. This doesnt seem normal...It seems to go away if i put it in park then drive again. Anyone run into this?

I don’t know what exact fluid Acura is using in this transmission but I think whatever fluid they are using is too thick when the weather is cold, if you live in California it’s no big deal, but I live in Minnesota and it can get to -30f in the winter before windchill, my car shifts rough just being in the 20-30s when first driving until it warms up and we still have 30-50 more degrees to drop in temp, I can’t wait to see how this car shifts when it’s transmission fluid is -30 degrees f 😂

The 8-speed automatic transmission in my brother's 2018 Chevrolet Colorado (and others) "hangs" in second gear for what seems like an eternity when the engine is cold.
If the transmission was actually "hanging" and not upshifting when commanded by the TCM, you'd get a warning light/message. Most likely, the transmission is "hanging" because it's being told to by the TCM. It could be a software bug that becomes apparent under some conditions or it could be an intentional warm-up strategy (assume it's only doing it when cold).
You're not in manual mode until you press the D/S button twice THEN pull a paddle shifter. Until you do the latter, shifts are still fully automatic.

Relax
Every vehicle with an automatic transmission I have ever driven in my nearly 60 years of driving does this to one degree or another. I think it is more noticeable as the number of gears increases - & I'll bet most of us have not previously driven a 10 speed (except bicycles).

In D, it will eventually get bored and go back to full auto shifting after a paddle yank, unless you keep yanking.
In S, one yank is enough to keep it in manual sequential mode.
If you refrain from yanking, S just alters the shift points and keeps the revs up, for Sportiness.
Having said all this, it is possible to yank by accident, and the consequences will be more apparent in S mode.
