MT88 shifting and grinding issues

[Ford Motor Company]

I’ve been driving manual cars for 16 years, all my cars have been manual and that’s why I wanted the Bronco. My last car 2006 Audi a4 has 280000 miles on it and it still shifts like butter.
Now with my new Badlands under 5000 miles on it I noticed when I push the clutch in and shift into any gear it lunges forward a little bit? It’s almost like the clutch isn’t fully disengaging the transmission. This sometimes happens at stop lights if I let the clutch out and press it back in before going into first gear. If I leave the clutch in after rolling to a stop it doesn’t usually do this. It’s very noticeable and the sound it makes is like a clunk almost like the gear/synchro is being slammed to a stop from rotating.

In the video you can see the wheel try to move forward when it shifts into 1st gear and you can hear the clunk. I shift it into first 2 times. Both times releasing the clutch in between.

is this normal for these?

Good morning. I would like to take a closer look into your shifting concerns. To get started, can you please send over a message with your VIN and mileage?

Years ago I replaced the clutch master cylinder on my '07 Jeep and after a month it started having similar issues. Did a warranty return with oriellys and a month later it started doing it again. For anyone who hasn't bled a clutch.... it takes more pumping than a night with 2 shots of Tequila and 100mg of viagra. I was irritated. So I took the cylinder apart and saw it was only a little plastic slot that allowed more brake fluid in when released. You could see the line on the plastic where the "plunger" wasn't quite hitting this line. Whether this was due to bad tolerances or a weak spring I don't know. But I gently increased the slot to a millimeter past the wear line on the piston cylinder. Drove that thing for another 100k miles till it was wrecked and it shifted like a dream the entire time.

I would assume the Bronco has a similar design. Uses the brake fluid reservoir as a supply, a plastic plunger (Hydraulic cylinder) behind the clutch to build pressure, and a slave cylinder to disengage the clutch. If you're mechanically inclined what I describe above is extremely easy to do and won't be detected by any dealer because they are not taking the clutch master cylinder apart to find out "why". So it's not going to hurt your warranty if it doesn't help. The wear line I'm talking about is pretty obvious when you disassemble the cylinder, if that's the issue. But I assume no responsibility for anyone who attempts this.

Now that you mention that the brakes do feel a little spongy.

Update.
Took it back in today and the service manager came out to test drive it with me. He agrees and wants to replace the hydraulic system for the clutch.

No, not normal, I have 28K on my manual 21 Badlands. Butter, although I did swap in Amsoil early on.

If you can bleed the clutch, start there.

I agree but can’t tell them what to do.

 

[Tonka Bronka]

Does this have a fluid tank? Or is it a sealed system?

Both

They share a reservior but that's about it. Glad you found a manager that's going to help!
