Hard downshifts on a 3.3T AWD?

I've had the 3.3T AWD for about 2 weeks now and just getting to 500 miles or so. Something I've noticed is that when lifting my foot from the gas pedal and attempting to coast, the car appears to slow itself down before I depress the brakes (hard downshifts?). It's jerky and abrupt - kind of like the regenerative braking on a Tesla if you've driven that. It appears to be more pronounced when in Sport mode.

Is that normal? I know I didn't feel this on the 3 test drives I took before I purchased the car but I may have just been overly giddy with joy on those drives to notice. I'm also quite the newb/noob when it comes to most things automotive.

Hi Jay, I don't have AWD but those that due may want to also know at what speeds is it evident? I drove a Tesla with the regenerative braking set on High and yes that quite a different feeling than without.

I'm not going too fast when this happens - it's usually as I coast right before a stop sign or a red light stop. Well under 30 mph.

It’s the 3-2 downshift and from what I can tell doesn’t have anything to do with rwd or awd. Mine is jerky too, but my last car was a Hyundai Genesis coupe auto that had the same exact hard shift on the 3-2 when slowing to a stop. Almost like the trans wants to go from 3-1 and doesn’t shift fast enough to have the rpms blipped for a smooth downshift through 2. I can avoid it by stopping faster lol, and yes it’s worse in sport

Edit to add that I know the trans is different but from what I can tell they still haven’t figured out how to get an in house performance auto trans to handle that 3-2 downshift

So I have to train myself to stop faster. Well at least I know it isn't an issue with the car.

I mean ‘stop faster’ isn’t always a good idea or feasible given the conditions so it’s also something you’ll have to live with. I think it can also be avoided by using the paddles and downshifting yourself through those gears, give it a try. You can also move it out of sport and into comfort when you’re stopping

Yeah I'm gonna try a few different things. I don't always notice it but when I do it's really obvious. Appreciate all the responses!!

Maybe I brake late. Haven't noticed any issues. Coasting doesn't work at that speed, so the engine is definitely in gear
I think the way this feels is very dependent on how you brakeand if you change pressure much on your way down to 0. For example I’ll feel it if I brake slow enough that I can feel the trans hitting each gear on the way down

^^^This. The transition is smoother out of Sport mode.

I have noticed it on the 3-2 downshift and the 2-1 downshift when in sport mode as well. I think it is just how the throttle is calibrated during the downshift and to be honest it is actually better than the ZF transmission in my old 535 when in sport. And a million times better than the ZF in my Grand Cherokee on sport. That one is so bad the entire vehicle 'bobs' during the downshift because of the soft air springs.

Ultimately for the G70 I find you either have to brake slower or faster to not notice it. lol

It’s a sport mode thing. The trans is programmed to feel more “aggressive” and intentionally holds onto the clutch packs longer to result in overlapping torques. I think it’s a bit silly and don’t like it when manufacturers do this (looking at you, BMW). Porsche for example knows that Sport Plus mode on their PDK isn’t meant to make the shifts more aggressive, which can upset the car’s balance during performance driving, but instead just holds on to gears longer, shifts faster, etc. No torque overlap though.

Hmmph.

I'll need to look for your issue on mine. I haven't noticed that, but I'll specifically check it out. Btw, I have a loaded up G70 3.3T AWD Sport too. Had three weeks w/ 820 miles (but dealer sold it to me with 160 miles on it! Whole nuther story) Btw, manual says not to use launch control before appx. 850 miles.

I've been experimenting too. Paddle shifters are good. I noticed that when shifting from drove to reverse to park, the trans is a kluncky.

I have a 2019 3.3 AWD and have the exact same "issue". In Sport mode I detected an unsmooth downshift from 3 to 2 and thought that I got a lemon. Hearing others having the same issue is reassuring (I guess), though I confess that I do not like it very much. The issue does not present in either ECO or Comfort mode so I am guessing this is all normal. Somewhat related: can we shift modes at any point in the drive? Or, should we only shift modes when the car is not moving?

OK to shift drive modes at any time.

Well it is sport mode!
