2018 F-150 10-Speed Transmission Shifting Rough - Is this normal?

0

Brian F. · rep 0 · May 22, 2:30 AM · 1 replies · solved · Question

Hey everyone, I've got a 2018 Ford F-150 Lariat with the 3.5L EcoBoost and the 10-speed automatic transmission. Lately, I've noticed some really rough shifts, especially between 3rd and 5th gear, and sometimes a hard downshift when coming to a stop. It feels like a jolt.

I bought it used a few months ago, and it wasn't doing this initially. Now, it's becoming more frequent and quite annoying. I'm worried this could be a major transmission problem.

Has anyone else experienced this with their 10-speed F-150? Is there a known TSB or recall for this? What should I be looking for, or what questions should I ask my mechanic?

Summary: For 2018 F-150 10-Speed Transmission Shifting Rough - Is this normal?, work through these steps on your 2016+ vehicle:

  1. Confirm the symptom — note when it happens (cold start, highway, after fuel fill, etc.).
  2. Scan codes — save all pending/stored DTCs; don't clear until you've recorded them.
  3. Check TSBs & recalls — look up your VIN for open campaigns and known fixes.
  4. Inspect the obvious — related fuses, connectors, fluid level, and recent repairs.
  5. Test the common fix — follow model-specific service procedures; one change at a time.
  6. Escalate if needed — burning smell, no brakes, overheating, or stalling in traffic → shop visit.
