The analysis found automatic car numbers jumped 118 per cent in the 10-year spell and over the same period manuals increased 2.4 per cent.
As such, there are now 37.5million manuals on the road, up from 26.6million in 2014.
While it shows the UK is still a nation of drivers who predominantly prefer being in control of their car's gears, there is evidence of a rapid surge towards automatics as already seen in other countries.
In the US and Australia, for instance, some 97 per cent of vehicles are estimated to be autos, with stick shifts very much the unpopular choice.
Solera cap hpi says the car parc data shows the popularity of automatic transmissions has increased exponentially since 2014, whereas manual volumes have been falling for the past five years.
Annual car sales data reveals that the number of automatics has almost tripled, from 538,000 new registrations in 2014 to over 1.5million in 2024.
In contrast, the number of manual vehicles registered dropped from 708,000 a decade ago to 274,000 last year.
These figures are somewhat reflective of the new models in showrooms today, especially as car makers ramp up their electric vehicle offerings, which are sold only with automatic transmissions due to the single forward gear setup of battery cars.
A study by CarGurus last year found that mainstream brands are rapidly reducing the number of new models with manual gearboxes, slashing availability by more than half in the last six years alone.
Manufacturers that no longer offer any new showroom models with manual transmissions include Volvo, Mercedes-Benz and Lexus.
Out of 300 models available to UK buyers last year, only 89 were manuals - 18 per cent fewer than in 2023, the market review found.
At its current rate of decline, experts say that by 2029 the manual gearbox could be all but extinct, like CD players and wind-up windows.
