Transmission issues

[Theblobishere92]

Hi everyone.. I picked up my Bronco 2.7L 4 door Base on June 2022. I have 10,800 miles on it.

Let me preface this, I'm no car expert.

About 2 months ago I started noticing my Bronco lurching and clunking when going from park to reverse when the engine was cold. Every single day when I start the truck for the first time in the morning and put it in reverse, it does this lurch/jump and a clunk noise. The closest thing I can compare it to is when you're parked on a hill and you shift gears -- you get that clunk and a lurch.

Other things I've noticed, maybe because of my heightened awareness, when I'm breaking from going 35-40 miles an hour, as the transmission shifts down sometimes it clunks or shifts weirdly, not as intensely as when I start it in the morning and put it in reverse. This is fairly random and rare, but it does happen.

I've been in the process of moving ~80 miles across the state, but I did take the truck into the dealer. Of course it worked seamlessly when I had the technician with me. He said they would need the truck for 2-3 days to check it out. Unfortunately because I was moving, I couldn't commit the Bronco for that long. I'm now working on getting it into a dealership near my new home.

I'm curious if something I could have done could have caused this? I haven't done any intense off roading, mainly beginner trails. I haven't towed anything either..
Does anyone have any idea what causes this to happen?

Probably not the cause but did you check the fluid level and fluid condition?

Yes I did, the dealership did an oil change for me and checked transmission fluids and everything checked out

Hi Ian. Can you send us a DM with your VIN and dealership info? I can look into this for you.

Accelerated main control break in followed by clearing the adaptive transmission learning. I always have very good luck with this curing most intermittent weird shifts with 10 speeds.
Ask the dealership about SSM 51531

Please keep us updated. I have noticed that exact same issue with my Bronco. Very curious about what @Ford has to tell you.

I’m not sure what any of this means, but I will show the dealership your message! Hopefully this is covered under the warranty.

Hey Chris, will do. I reached out to Ford via DM about 2 hours ago with my VIN and dealership.

No reason it shouldn’t be covered under warranty.
Here you go, this should help.

Hello, Chris! Send us a private message with your VIN and the name and location of your local Ford dealer. I’d be happy to see what I can do to assist with this transmission concern. Thanks!

@Ducati1098 looks like you were right. It was the transmission control module.

Glad they got it taken care of for you. Are the shifts back to normal now?

 

[Theblobishere92]

Generally, it seems to be shifting much smoother. I think I had gotten used to hearing it shift throughout normal operation., now it's smooth as butter. I haven't had any down shift issues while driving at higher speeds then coming to a stop.

I won't be able to tell if there are issues going from park to reverse until the engine is cold tomorrow morning.
