Clutch Bouncing

[TheSSBoz]

Mine does this as well occasionally...

Seems fuel related like it wants to stall (and then I have tried to put my foot down on the skinny pedal to no avail)...or as I said in another thread like its being rev limited but you are only at close to 3k RPMS in first gear....once you hit second its fine

Somewhat off topic....That first gear is just a dog sometimes. I put it in sport mode just to get it to take off like a normal engine (more fuel applied with same amount of skinny pedal input)

On a related note, my F-150 with auto transmission had a habit of bucking like crazy anytime I'd come to a slope or hill if I was "lugging" it at lower RPM's. I swore it was transmission or torque converter related, but it went away after I had the spark plugs and coil packs replaced. I had no idea it was a miss, as it ran fine 99% of the time.

Not to whine, but what about the Ben that started this thread with the same issue?

And who lives somewhere they can actually help, instead of offering and then later telling you they can't?

Thanks Mike and touche...speculation has changed to fuel delivery...

6pgs of folks reporting similar, but hard to document issue here. Whatever it is hopefully it goes away completely on mine, I'm over 17k miles now and am noticing less frequently (but still present).

ECU or some other chipset may be 'learning' or I'm properly breaking it of its bad habit...what do you think?

Mine has never done that. The only 4cylinder I owned that would shake when warming up was my 2014 focus and that cleared up after I changed the spark plugs (which they claim where 100k plugs, but just had the 100k service done at 60k to take care of everything). I would be curious if maybe you folks are getting some bad gas.

I'm getting the bucking in 1st and 2nd gear as well with only 700 miles. Only have had this thing for 3 weeks. I thought it was me for abit, but now it's happened about 4-5 times and started at 500 mile mark. Does seem to happen everytime the engine is below ideal temp.

Hi there. This concern doesn’t sound like something we want you to experience with your Ford Bronco. Could you please send us a DM with your VIN and dealership information? I'd be happy to look into how I can assist you on my end.

Any progress on this? I’m nearly 15k in and this happens intermittently. It didn’t do it for a few months and then it did the other morning. I attributed it to being the chilliest morning we had in a while.

Posting here for additional documentation.

I'm having the same issues as OP with my black diamond 7MT. Bucking in 2nd when the engine is still cold. No foot on the clutch pedal. about 3100 miles on the vehicle.

Also a clunk moving from 1st to 2nd but only when the engine is still cold.

Y'all aren't talking about bucking that can occur with a manual trans during light throttle and low rpm such as going through a parking lot, right?
This something different and more random?

I once had an aftermarket clutch that would chatter during engagement when cold. The company's solution was to dump the clutch at 3k rpms a few times. Lol.

No. Much different, more violent, and usually around 3000 rpm. Comes out of nowhere while accelerating.

Posting on this thread also for it to be seen. 5400 miles on my 2dr 7MY black diamond. Violent bucking for several seconds while in second gear today when first driving it this morning. Warmed up engine about 3-4 minutes before driving. 65°F outside temp at the time. Happened while driving in second gear, I would say around 2600 RPM or so. Only ever have ran 93 octane fuel from Shell since brand new. Felt like possibly the engine wanted to stall or wasn't getting enough fuel. Clutch wasnt pressed at the time, I was just driving down the driveway.

I managed to capture my issue on video. Is it similar to what you've been experiencing?

After a month at the dealer they were unable to reproduce the issue and attribute it to either not enough pressure on the gas pedal (wrong!) and resting my foot on the clutch (wrong again!):

That. Is. The exact thing. I was experiencing that was cause for me creating this thread...

Un/fortunately another driver ran a stop sign and sent my MT to its forever home...

Loving my 10spd AT and all the tricks it has so far/not missing crawl gear with one pedal drive as a substitute (queue the chair throwing MT diehards?)...

Hi there, I'd be happy to look into your Bronco concerns on my end. Will you send us a message with your VIN and dealership info? I can look into things on my end.
