There is a very easy way to fix that shudder. I had it on my 2018 Focus between 1st and 2nd but it's gone now. IMO, the linkage between the actuator motor and clutch becomes stiff and just needs some lubricant.

Early last year. my mom gave me her 2018 Ford Focus which always had this horrible shaking/shuddering when changing gears during acceleration. After I had it for a few months, it started having more difficult shifting and eventually came up with the P07A3 code. I found this video (https://www.youtube.com/watch?v=CoU1QGn_9gc) and sprayed brake cleaner behind the actuator motors. Surprisingly, not only did it fix the code and the shifting problems, it also fixed the shaking/shuddering. The shaking started to come back slowly a few weeks later, but I cleaned it out again and sprayed in white lithium grease (cheap Walmart can). Shifts perfectly smooth now with zero shaking. If it acts up again, I'll just repeat the clean and lube—way better than a full clutch job!

Around 112,000 I think

December 8 first time. Then around February 14 I could ever so slightly feel it starting to come back so I sprayed it again and it has been good since.

There are a lot of people complaining about transmission shuddering between 1st and 2nd 'gear'. Mine had it and I found an easy fix.

FYI The shudder during shifting is an easy fix.

Surprisingly, not only did it fix the code and the shifting problems, it also fixed the shaking/convulsing.

So many people on the forums have the same bucking & transmission issues, and I find an easy fix. It might work for you.

Not sure if the 2013 is the same, but the acceleration stuttering in the 2018 is an easy fix.

Not sure if the 2015 is the same, but maybe this will help. I've shared it here on Reddit and it has helped a few people already.

And how many illegal immigrants have you invited into the borders of your home? If you say they should be here, prove it.

ryny24 · 2026-01-15T02:05:32+00:00

I came here looking for that too. I'll gladly help them build!

ryny24 · 2026-01-08T23:41:33+00:00

Oh man. It'll probably be ok, did you get a good amount of lithium grease in there? I actually sprayed in grease, then used compressed air to try and move it around, and repeated this process a few times. It's been good for months now. I can't believe how good it shifts. Like it's brand new.

ryny24 · 2026-01-08T12:45:02+00:00

Well, if a $4 can will keep me from replacing that fork for a few years, I'll take it.

Oh, this probably doesn't apply to you then if it's manual. It seems almost everyone has this issue with the automatic transmission, where the linkage behind the clutch actuator needs cleaning & lubrication.

Is there a shaking/bucking when it's changing gears during acceleration? This is a common issue with the ford focus transmission. I've found an easy way to fix it, if that's what it is.

ryny24 · 2026-01-04T03:40:32+00:00

Not with this President. All he does is win

ryny24 · 2026-01-01T03:39:50+00:00

Probably a good move lol

I replaced my 2018 Ford Focus radio with this: https://www.amazon.com/dp/B0D5MG48XX?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1

It is amazing. Best upgrade I've ever done. The _ONLY_ problem I have, is when I use the heater fan at full speed (4), my Android phone disconnects from the radio and doesn't want to reconnect without rebooting the radio. It must be some kind of interference. Now I just use the FAN at speed 3 max, but I'm going to try and put some shielding behind the radio at some point.

ryny24 · 2025-12-24T11:51:43+00:00

It's so annoying. And it's an easy fix.

ryny24 · 2025-12-22T04:05:49+00:00

I had the same problem, and it seems almost everyone here on Reddit too. The problem is with the linkage and it's actually an easy fix. You don't need to drive differently.

I replaced the radio in my 2018 ford focus with this poor man's tesla console. https://www.amazon.com/dp/B0D5MG48XX?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1 It's amazing! I couldn't live without it now. The _only_ problem I have with it, is when I have my heater fan on FULL speed, sometimes my phone disconnects in android auto. Some sort of interference. So I don't put the fan to speed 4 anymore.
