Thanks for the suggestion bud! Drives/accelerates much better, no hesitation ... who knew?
We all knew lol...but welcome to the club...it's the only way to drive in stop n go traffic...
I shall try that as well! Thanks much NotBudule!
Mine does this too on certain corners. There's a roundabout here that's a particularly bad offender. Hard on the throttle to get in to the roundabout, off the throttle going around, then when I get on it to exit, nothing for 2-3 seconds until it decides to allow power and it takes off. Also get it sometimes accelerating from almost a stop, like when you're rolling forward for a left turn at an intersection then decide to punch it. It sucks when you put your foot down to go left through a gap in traffic and the truck just sits there for a few seconds.
Mine did it when new (also a 2019) about 30k now. The dealer flashed the transmission so.it would relearn my driving habits. Worked fine for a few years but it started back up in the last few days. Wondering if there are any transmission fluid additives that might help?
I just went through the transmission nightmare, though his symptoms don't sound like the rest of ours as we had rough shifts and I even had gears simply not work. It may be the earliest stages of it but he also may just be experiencing turbo lag or the ASS system and misidentifying it. No disrespect to OP I don't know him but it could be nothing.
Even in S mode, dropping the hammer from stand still, there is an initial fraction of a second "soft" launch then it starts to pull hard...I suspect this is boost lag...
For sure, Even though twin scroll turbos largely eliminate boost/turbo lag they still do need to rev up a bit. I think the turbo really kicks in around 2 and change thousand RPM so you will definitely feel some lag if you send it. Also I think the tcs does some stuff to prevent wheelspin as well. All that aside factory throttles definitely have some input lag, hence a ton of aftermarket programming kits that sharpen up the response.
Hit it exactly on the head, even with a twin scroll turbo there is still an appreciable amount of lag. Also even worse the systems are programmed to by a tad sluggish (which there are tuning tools to fix)
I have to drive in a 25 MPH zone for a couple of miles when I leave work. My truck hesitated and lugged a lot, running as high as 7th gear at 25-30 MPH. I started using "Tow Mode" (per a suggestion from group members) until I get to a higher speed zone. That made all the difference. The towing algorithm makes for much smoother shifting, but obviously fuel economy takes a hit. But for a couple of miles it's worth it. My only other issue is it seems to shift hard into and out of 8th gear under lower torque situations.
I would have them take a look at the valve body, hard shifts like that are the first symptom of it going bad.
