This is the narrower sheet inside transmission shudder for shifts that jerk, lurch or bang. Where the wider sheet also takes in slipping and vibration, these reports are about a shift that arrives too hard: the car lunges forward, or a clunk comes through the floor as it drops into gear.

Part of Transmission Problems (Shudder and Hard Shifts), which counts 15,027 reports.

The 25 vehicles with the most reports

Each row is one model year. The bar is its count of jerking or hard shifts reports; the share is how much of that car's complaint file this problem takes up. Bigger sellers draw more reports, so read the share alongside the count. Red dots mark crashes and fires in these reports; amber marks a recall on the same system.

What it is and what to do

About 7,400 complaints on this site describe it, which makes it the largest of the three transmission sub-sheets. Four in five use the words jerk or lurch, and more than a quarter mention a clunk, bang, slam or jolt. The part that separates this from a comfort complaint is the traffic: more than one in five mentions an accident, a hit or a near miss. The median mileage given is about 43,000, and the 2014 Ford Focus, 2014 Jeep Cherokee and 2018 Ford F-150 top the list.

Firestone treats shaking, jolting and kicking during shifts as a sign that something is wrong, and says automatic shifts that become more jarring than you're used to are worth a check-up. Its first suspect for poor shifting is low or contaminated fluid. About one owner in nine here mentions a software update or reflash.

Expect a scan for codes and a fluid check. Tell the mechanic which shift it happens on (first to second, a downshift as you slow, or into drive or reverse from park), whether the engine is cold or warm, and whether it has ever pushed the car into traffic. NHTSA's recalls turn on safety risk, so put that detail in any complaint you file with it.

Check NHTSA's recall lookup and the manufacturer bulletins NHTSA posts. Report it during the powertrain warranty and keep the repair orders; the FTC says a defect reported in the warranty period must be fixed even if the warranty expires before the repair.

Counts are unique NHTSA complaints on the 1,040 vehicle model years that have a page here, grouped by the word patterns described on the method page. A vehicle needs five matching reports to be counted in this ranking. Checked Sep 27, 2026. All problem explainers.
