What happened to the OP?

In what way do you mean? I've been responding to a large number of posts

So what about changing the oil remedies this in your view? Just changing oil shouldn't have any measurable change.

I can't explain it either, but mine seems to shift better, smoother after the flush and adding Lubeguard Platinum.

I wondering what happened to you and your truck.
What did you decide was wrong? What will you be doing about it?

In that way.

Gotcha
I'm going to take to the dealership to test drive (upshift from 1-3 are getting worse), but for that I've been trying to get more info by trying to induce different failure modes or rough shifts. So far there hasn't been any stalling like that one time.

Okay, so when my truck did it......it was like it just shut off.
Then came back to life
So @airline tech ........
Now i have to note my steering angle?!?!?!?!?!?!??!?!??? Wtf??
I knew it, these trucks are so nannied out, i drive with tc off. Not the 10 second hold the button down but just the quick press. Thats just crazy the computer controls so much.
Almost makes me want carburetors and points again.

Mine is doing something similar. I'm going to try Lubegard and see what happens

It is easier to do if you have the MBS Dispstick installed. Open hood and insert the tube down the dipstick tube, and it will fill the jugs just fast enough to allow you to monitor and not spill a drop. Put in the new fluid leaving enough room for the LubeGard platinum. I had an immediate and profound improvement. Truck shifts like new.

I installed that dipstick. It was easy to do.

This is the pump I used $25. I hooked it up to a 40 year old 12v battery charger that I had in the garage. I am changing the trans fluid one more time when I hit 25K miles and change the engine oil. That will happen in another couple of weeks. or 350 miles, whichever comes first.

If you go this route add a brass fitting to the end of the outlet hose to help keep the hose in the jug. It will tend to want to fly out without the weight.

One more thought. Check your fluid level after letting the truck set overnight before doing the change, and make a note or dimple the dipstick at the level. When you replace the fluid let the truck sit overnight without moving it. The fluid level should match the dimple.

It's another double check. The transmission fluid level is sensitive to inclines and most garage floors have a slant to allow water to flow out the garage. That slight incline will cause you to overfill if you are not careful.

Anyone had their transmission simply not respond for a longtime, when flooring it?
I was on the highway recently, and was merging into traffic from a near-standstill (as is normal).
I was half out of my lane, with high-speed traffic in the lane I was merging into, and floored it while in D mode to merge into the lane.
Simply nothing happened for SEVERAL SECONDS(like 3 seconds). It seems like I lost all wheel power. Not even slow movement while turbo spun up -- simply 0 power.

After those few seconds, the vehicle finally started accelerating. I didn't move my foot so no, I hadn't been accidentally pressing the brake

Anyone had this before?
Is this a transmission issue? Engine issue? Either way it was extremely unsafe.

yes. My 2019 does it all the time. I just figured it was the throttle by wire. Or 10 speed. But, if my revolutions are up, it’s normal. Fellow on here explains it correctly, I think. (Exhaust gases, etc)
Good luck!

Most drive by wire vehicles for some reason seem to have a little bit of lag built in. I don't know why, maybe it's a "safety" feature to stop them jumping away if you accidentally bump the throttle, maybe it's designed as a soft start to make life easier on the driveline. I do know, it can be extremely annoying at times, combine it with turbo lag and you have a double whammy effect. It's even worse on my diesel model, diesels being naturally a little bit slower to spin up. I find a steady push to the floor often responds much faster than suddenly slamming it down.

The lag is to help with the noise and clunking from the driveline lash on vehicles with traditional transfer case and driveshaft setups.

All other times i've floored it, no issues. This one occurrence almost caused me to have a serious accident -- if the cars I was merging into didn't respond in time and quickly hit their brakes while my vehicle froze in their lane, I would have gotten hit.
So I don't believe a drive by wire lag is what occurred here.

And agreed that smooth push to floor can be good. But since flooring it has always worked, and this time the truck basically died, it's confusing why there was different behavior that one time.

I would take it to the dealer. For all you know there is an open investigation against claims like this. I worked for a manufacturer and there was a software release that came about due to the complaints over harshness. Under certain load, ambient temp, speed etc people would experience what you just did. It only takes 10 or so claims to get traction for a fix. Just because there aren’t complaints here on the forum doesn’t mean there isn’t a wider issue. Good luck!

It sounds more like an engine issue, rather than a transmission issue. Was the engine roaring and the truck not moving?
