CIMA was founded in 1942 as a manufacturer of gear machining equipment before producing its own gears in 1946. Beginning in the 1950s CIMA supplied gears for automobile and motorcycle racing applications,[1] including Scuderia Ferrari,[a] Porsche, Harley-Davidson,[3] Minarelli, and Honda.[4] In 1980 what is now the Coesia Group purchased CIMA, who went on to expand the into more machinery markets as well as marine applications.[5] In the 90s, CIMA expanded its reach to the aeronautical industry and found more success in racing.[6] After advancing their low pressure vacuum carburizing and gas quenching methods in 2002, CIMA developed even higher performance transmissions for road and race applications. Their transaxles[b] are found in many low volume supercars.[c][13][2][8]

...the Arrow comes with a 4.0-liter twin-turbo V8 unit, good for 1,000 PS and 1,000 Nm (737 lb-ft). Those numbers are being put to good use through a fully synchronized sequential 7-speed CIMA transmission with a twin plate clutch configuration.

At the center of the Hussarya, we find a supercharged GM 6.2-liter V8, which churns out 650 hp and 604 lb-ft (818 Nm) of torque. This is mated to an automated manual transmission. Supplied by Italian producer CIMA, the gearbox offers six ratios.

A sequential paddle shifter is under consideration for the Zonda, but the six-speed manual built by CIMA will be the only gear set offered for a couple of more years. As great as the Lamborghini's six-speed manual is, the Pagani's is a marvel of its own.

The new transmission, sourced from Italy's CIMA, features seven forward gears and a single clutch. Gear shifts are said to take place in as little as 35 milliseconds, making this one of the fastest shifting, single clutch transmissions in the world.
