Gear shifting statistics at a glance
Gear shifting statistics show a long, measurable move away from short gear stacks and toward higher-speed automatic systems. The pattern is not linear, but the dataset makes the direction clear: more gears, more lockup automatics, and less dependence on manuals over time (EPA 2022 Automotive Trends Report).
Fast facts
- Manual transmissions fell from 23.0% in model year 1975 to 0.9% in model year 2021 (EPA 2022 Automotive Trends Report).

How gear shifting changed over time
The most important story in the dataset is not simply that transmissions changed, but that the entire distribution moved. In the mid-1970s, the transmission mix was dominated by automatics without lockup, while manuals still represented a meaningful share of production (EPA 2022 Automotive Trends Report). By the 2010s and 2020s, the mix had shifted toward higher-speed automatics, CVTs, and fewer low-gear configurations.
That shift shows up in three related ways:
- Manuals steadily lost share from double digits into low single digits.
- Lockup automatics became the dominant automatic type.
- Transmission gearing spread upward, with 6-speed, 8-speed, and 9+ speed designs taking much larger roles.
The dataset also shows that change happened in stages rather than all at once. In some years, the biggest move was in automatic lockup share. In others, it was the rise of 6-speed or 8-speed layouts. The result is a decade-by-decade picture of gear shifting statistics that tracks engineering change more than marketing language.
Transmission mix by model year
The year-by-year transmission mix is the clearest way to see the transformation. The table below keeps the most comparable benchmarks together so the trend is easier to read.
| Model year | Manual | Automatic with lockup | Automatic without lockup | CVT hybrid | CVT non-hybrid | Avg. number of gears |
|---|---|---|---|---|---|---|
| 1975 | 23.0% | 0.2% | 76.8% | - | - | - |
| 1980 | 34.6% | 18.1% | 46.8% | - | - | 3.5 |
| 1985 | 26.5% | 54.5% | 19.1% | - | - | 3.8 |
| 1990 | 22.2% | 71.2% | 6.5% | 0.0% | 0.0% | 4.0 |
| 1995 | 17.9% | 80.7% | 1.4% | - | - | 4.1 |
| 2000 | 9.7% | 89.5% | 0.7% | 0.0% | - | 4.1 |
| 2005 | 6.2% | 91.5% | 0.1% | 1.0% | 1.3% | 4.5 |
| 2010 | 3.8% | 84.1% | 1.2% | 3.8% | 7.2% | 5.2 |
| 2015 | 2.6% | 72.3% | 1.4% | 2.2% | 21.5% | 5.9 |
| 2020 | 1.1% | 68.3% | 2.7% | 2.8% | 25.0% | 6.9 |
| 2021 | 0.9% | 67.0% | 5.4% | 4.7% | 21.9% | 6.6 |
| 2022 prelim. | 1.0% | 63.3% | 9.9% | 4.6% | 21.2% | 6.5 |
A few patterns stand out immediately. First, manual share shrank almost continuously across the series, moving from 34.6% in 1980 to 0.9% in 2021 (EPA 2022 Automotive Trends Report). Second, the automatic category did not stay static: lockup automatics took over and remained the dominant transmission type through the later years. Third, CVTs became a meaningful part of the mix, especially in the 2010s and early 2020s.
Big number
Automatic transmissions with lockup reached 91.5% in model year 2005 (EPA 2022 Automotive Trends Report). That is one of the strongest single-share readings in the dataset and a sign of how concentrated the transmission mix became before the later widening into multiple high-speed formats.
What the gear-count trend says
The gear-count data is as important as the transmission-type data because it shows how designs evolved inside the same general automatic category. In the early years, most production sat at four gears or fewer. Later, the share moved decisively toward six, eight, and nine-plus speeds.
Gears over time
- In model year 1975, transmissions with 4 gears or fewer represented 99.0% of production, while 5-speed transmissions were just 1.0% (EPA 2022 Automotive Trends Report).
- In model year 1980, transmissions with 4 gears or fewer were 87.9%, 5-speed transmissions were 12.1%, and the average number of gears was 3.5 (EPA 2022 Automotive Trends Report).
- In model year 1990, transmissions with 4 gears or fewer were 79.9%, 5-speed transmissions were 20.0%, and 6-speed transmissions appeared at 0.1% (EPA 2022 Automotive Trends Report).
- In model year 2005, 5-speed transmissions jumped to 37.3%, 6-speed transmissions were 4.1%, and 7-speed transmissions were 0.2% (EPA 2022 Automotive Trends Report).
- In model year 2010, 6-speed transmissions became a major mainstream format at 38.1%, while the average number of gears reached 5.2 (EPA 2022 Automotive Trends Report).
- In model year 2015, 6-speed transmissions rose to 54.2%, 8-speed transmissions reached 9.5%, and 9+ speed transmissions were 3.5% (EPA 2022 Automotive Trends Report).
- In model year 2020, 8-speed transmissions reached 28.8% and 9+ speed transmissions reached 21.2%, pushing the average number of gears to 6.9 (EPA 2022 Automotive Trends Report).
- In model year 2021, 8-speed transmissions were 32.5% and 9+ speed transmissions were 22.4%, with the average number of gears at 6.6 (EPA 2022 Automotive Trends Report).
- In model year 2022 preliminarily, 8-speed transmissions remained high at 30.3%, 9+ speed transmissions were 25.2%, and the average number of gears was 6.5 (EPA 2022 Automotive Trends Report).
Why that matters
The growth in gear count is a useful proxy for how transmission tuning and efficiency priorities changed. More gears can help manufacturers spread ratios more finely, and the dataset shows that this became increasingly common over time. The shift is especially visible when you compare the early 1980s average of 3.5 gears with the 6.9 average in 2020 (EPA 2022 Automotive Trends Report). That is not a small tweak; it is a different transmission era.
Manuals, automatics, and CVTs
The most readable way to interpret the dataset is to treat manuals, automatics, and CVTs as three separate phases of a longer shift. Each phase has its own momentum.
Manuals: from normal to niche
Manual transmissions were still a substantial part of production in the 1970s and 1980s. They accounted for 23.0% of production in 1975 and 34.6% in 1980 (EPA 2022 Automotive Trends Report). After that, the decline becomes persistent:
- 26.5% in 1985
- 22.2% in 1990
- 17.9% in 1995
- 9.7% in 2000
- 6.2% in 2005
- 3.8% in 2010
- 2.6% in 2015
- 1.1% in 2020
- 0.9% in 2021
- 1.0% preliminary in 2022 (EPA 2022 Automotive Trends Report)
That series shows a long transition from a common choice to a niche configuration. By the 2020s, manual gear shifting had become a very small slice of production.
Automatics: lockup becomes the standard
Automatic transmissions with lockup are the center of gravity in the dataset. They began at just 0.2% in 1975, rose to 18.1% in 1980, and passed the halfway mark at 54.5% in 1985 (EPA 2022 Automotive Trends Report). They then expanded to 71.2% in 1990 and 80.7% in 1995. The peak share was 91.5% in 2005, before easing to the high 60s in the 2020s as other transmission types grew.
This is one of the strongest examples in the dataset of a technology becoming a default rather than an option.
CVTs: small early presence, stronger later role
CVTs do not appear in the earliest years, but once they do, they become increasingly relevant. The data shows 0.0% CVT hybrid and 0.0% CVT non-hybrid in 1990 (EPA 2022 Automotive Trends Report). By 2005, CVT hybrid was 1.0% and CVT non-hybrid was 1.3%. In 2010, CVT hybrid was 3.8% and CVT non-hybrid was 7.2%. By 2015, CVT non-hybrid had surged to 21.5%, and in 2020 it reached 25.0% (EPA 2022 Automotive Trends Report).
That makes CVTs a major part of the later-era shift in gear shifting statistics, even if they never dominate the total mix the way lockup automatics do.
Notable transitions by decade
A decade view makes the progression easier to summarize without flattening the data.
1970s and 1980s
- The 1975 mix was still heavily centered on automatic transmissions without lockup, which represented 76.8% of production (EPA 2022 Automotive Trends Report).
- By 1980, manuals had grown to 34.6%, and the average number of gears was still only 3.5 (EPA 2022 Automotive Trends Report).
- In 1985, automatic transmissions with lockup moved to 54.5%, overtaking other categories and signaling the next phase of design.
1990s and 2000s
- In 1990, automatic transmissions with lockup were already at 71.2% (EPA 2022 Automotive Trends Report).
- By 2000, they reached 89.5%, while manuals fell to 9.7% (EPA 2022 Automotive Trends Report).
- In 2005, lockup automatics peaked at 91.5%, while CVTs began to enter the discussion in a measurable way (EPA 2022 Automotive Trends Report).
2010s and early 2020s
- In 2010, 6-speed transmissions became the largest gear-count bucket at 38.1% (EPA 2022 Automotive Trends Report).
- In 2015, 6-speed transmissions reached 54.2%, while CVT non-hybrid climbed to 21.5% (EPA 2022 Automotive Trends Report).
- In 2020 and 2021, 8-speed and 9+ speed transmissions together became one of the biggest transmission blocks in the dataset (EPA 2022 Automotive Trends Report).
- Preliminary 2022 results still show a high-gear, high-automatic market with an average of 6.5 gears (EPA 2022 Automotive Trends Report).
Key takeaways from the dataset
The numbers point to a few durable takeaways for anyone tracking gear shifting statistics:
- Gear shifting moved from low-gear, mechanically simpler layouts toward higher-speed designs.
- Manuals declined from a major share in the 1970s and 1980s to around 1% in the 2020s.
- Lockup automatics became the core transmission type for most of the period.
- CVTs emerged later and grew into a significant supporting category.
- Average gear counts rose from the mid-3s to the high-6s over the period covered.
- The dataset suggests that transmission technology advanced in waves, not in one sudden jump.
The most useful way to read the full set is to keep two questions in mind at the same time: what transmission type dominated production, and how many gears did it typically use? Those two measures together explain the strongest movement in the data (EPA 2022 Automotive Trends Report).
