Gearbox manufacturers, such as Getrag and ZF, supply many of the world’s passenger vehicles with transmissions and while gearboxes are often identical between models from varying brands, they can differ dramatically in cost.

As reported by Road and Track, the Ford GT is equipped with Getrag’s 7DCL750 dual-clutch seven-speed ‘box. This transaxle-type system can handle up to 553 lb-ft of torque and an input speed of 9500 rpm, making it a popular choice for sports car and supercar manufacturers.

Throughout the years, this gearbox has been the sole option for vehicles like the Ferrari California and 458 Italia, as well as Mercedes-Benz models like the SLS and AMG GT.

In the case of the Ford GT and Mercedes-AMG GT, the transmission has a similar housing and largely identical internal parts. As a matter of fact, the two cars feature identical gear rations in first, second, third, fourth, fifth, six, and seventh gears. They even share the identical 3.67 final drive.

Despite the similarities between the transmissions, prices for replacements differ greatly.

Those looking to get a replacement Ford GT transmission will have to cough up at least $27,624. However, that price only applies to customers who can turn in a separate GT transmission to be replaced. If customers don’t have one to turn in, an additional $5000 is charged, bringing the total price to $32,324. That’s a lot of money.

To put those figures into perspective, the 7DCL750 transmission of the Ferrari 458 Italia is available to purchase for approximately $22,186 through some online retailers. The AMG GT gearbox is even cheaper, retailing for just $14,940, or roughly half of what’s required for a GT replacement transmission.

It remains unclear exactly why the Ford’s gearbox is so much more costly but the fact that so few units of the GT are being produced is probably a factor in the higher price.
