Do some research. The latest gen Taco manuals are having issues.
Well thank you for the heads up , I have done little to no research on issues for cars I'd potential replace this with.

Well, I got my Bronco back last night. It ended up getting a brand-new transmission. The new one is a B revision which I thought was weird because it originally had a C revision in it. Also the new transmission is doing the same thing as the old one and it doesn't even have 50 miles on it.

So still rattling or 2nd-3rd gear engagement?

B and C are both the same transmission, just a different engineering number. This is why basing "revisions" off engineering numbers doesn't work.

has a weird feeling going into 2nd and 4th most of the time and I'm willing to bet 3rd is going to start grinding soon.

Being a new transmission I wonder if maybe the issue is the clutch and/or shifter?

^^^^ This all day, I think the Rattle/Grinding is likely a totally different issue from the problems @DaddyLoafn is having with shifting, which sound much more like an issue with full clutch disengagement, and would usually be related to the linkage to the clutch pedal, hydraulic master/slave, and clutch fork/throw-out bearing travel. Did the dealership look at any of that?

No I don't think they did. I think y'all may be on to something, like I felt it happen the first time I shifted into 2nd while I was leaving the dealerships parking lot. They forgot to put the insulation/ sound deadening material on the inside of the new top, so it has to go back anyways.

lol, I feel like I'm crazy for thinking this, but it seems to happen more frequently if I'm turning left while shifting into 2nd. But that could just be a coincidence lol

I don't think that's crazy at all... Hear me out... Turning left and pulling back on the stick at the same time, you might actually not be pressing as hard on the clutch pedal. Inertia is pushing your body right, and your right arm is also pulling you right... that along with a marginal clutch already could certainly exasperate the problem!

Just got off the phone with the service advisor and he said that the tech opened up the old transmission and said that it should just be replaced, and I forget his exact wording, but he reiterated that the transmission was brand new and that there wasn't anything they could for the transmission itself unless Ford comes out with something different. I told him about thinking it was something other than the transmission like peddle linkage, clutch or something in the hydraulics. So, I guess I'll figure out more when the insulation for the new top comes in and in the meantime I'm going to do some testing to see if i can figure something out lol.

I am curious to ascertain the comparative success rate between Broncos that received new transmissions and Broncos that had the TDB.​

Do you have a weird feeling going into 2nd that if you don’t let it basically “drop” into the gate at its own pace it feels like garbage?

yes basically, and it'll do it in 4th gear to but it's not as bad. And 3rd gear feels like it wants to grind half the time and the other half it feels perfectly fine. Like it feels like the transmission on the 1987 Kubota we had on the farm I grew up on. I'm half wondering if this is just a quirk with this car or transmission in general but before I bought this, I test drove a use 2023 badlands and don't Rember thinking anything abnormal about how it shifted and even Rember thinking it felt almost identical to my Focus RS. I'm now looking for one somewhere near me to go drive and see if it feels the same but there isn't one with in like 50 miles of me right now.

Something I discovered over the weekend was that if I give her the old Italian tune up, launch it, shift at 5k and shift hard; all gears feel fine.
