Does anyone get an audible/tangible lugging or vibration sensation when cruising around 40-55 mph while in higher gears (8-10) @ 1300-1500rpm?

8-10 seem a bit high of a gear for 45-55 mph, at least if accelerating. Are you in normal mode? If you give gas does it hit boost and/or downshift and accelerate fine? I do notice mine gets a bit aggressive with going to higher gears to keep the RPM low and in that speed range above 40 and just shy of highway speeds 60+. It is okay on flat holding speed but just barely. It will lug and vibrate a little trying to maintain speed if I hit a hill or if go to accelerate. It isn't severe, but it is annoying enough I hit the minus thumb button on the shifter to downshift as I start on a hill to avoid the lugging. If I don't hit the button to manually shift it and instead just give enough gas to push into boost, either the boost gives enough torque to stop the lugging ,or it downsifts on its own.

This is in normal mode and when applying light throttle in the 40-55mph range. The behavior you describe is exactly what I am experiencing. I usually either “blip” the gas to force a downshift or use the +\- on the shifter. I have seen a lot of topics for this on the ranger forums, but was surprised to find little to nothing on bronco6g regarding this driveline behavior. Thank you for your response!

How long have you owned, mileage? Remember, these new trans learn your driving behaviours, but takes time. Dont let your engine lug, ever. Use sport mode and teach your trani a lesson or two!

Sounds pretty normal then.

I have tied sport mode and find other annoying things.

To an extent transmission behavior is somewhat related to the driver so not all will experience the same thing. On my 02 explorer, every time I've have the battery disconnected for some time, the trans falls back to factory defaults till it re-learns. The default always seems to shift pretty smooth to me even though shops warn it "may shift hard" till it adapts. Inevitably it learns my bad driving habits and starts to shfit worse.

I have a 2023 base 4-door. I’ve had it for just under a month and recently crossed 1k miles. I know break-in is considered to occur within the first 1k miles, but in reality, it will take longer than that. It does seem to be getting better, so I will just carry on. I honestly might be babying it too much, so that might have to change here after the first oil change coming up.

Stay below 3000 rpm until 1st oil, i would do that at 2000 miles, but after warm up, put pressure on that engine up to 3000. Find a hill or mountain, use M and manually pick your gears, then gently wind up rpms, keep going up and down in rpms. Remember that a full cool down is just as important, so do it several times. Good luck!

Mine does this, especially on a grade, 30-40 mph, more pronounced since I went up a tire size. Just the trans getting into a higher gear sooner than ideal. F150s had a real problem with this to the point at least two customers traded their trucks because there's no "fix" beside the customer moving to somewhere where they don't have a daily drive in hilly terrain with speed limits in the 30-50 range.

Yup similar situation, I'm going on 2,000 miles now & it's starting to smoothen out, either that or I've adapted...who knows...

Modern engines and vehicles do not need such babying from new. And the regimen you describe was not even gospel 55 years ago when I was first driving.

Even the cautions against maintaining a steady highway speed for more than 10 minutes at a time or never exceeding 55 mph until after 500 miles are nowadays pure bunk.

Knock on fake plastic wood dash but I have crossed 28,000 trouble free miles on a 2.7 built in the danger zone of valve fail units. First oil change at 7500. Second at 12k third just recently and following the internal algorithm. 20 mpg overall. I have held loose reins on Bucky from day one and he likes to run.

Stop treating your Broncos like they are Yugos. Drive them like they were meant, pass every Wrangler
