The American GM group has decided not to limit the introduction of 10-speed automatic to niche cars. Within two years, all key models of General Motors with the longitudinal arrangement of the power unit will be equipped with the new automatic transmission.
Increasing the number of gears in automatic transmissions – a controversial decision, giving a theoretical advantage in efficiency, but leading to a rise in price of assembly and risk of reliability reduction. Not all automakers have decided to follow the path chosen by GM’s, but the Americans are determined to pass it through.
A few years ago, General Motors and Ford have agreed on joint production of a new generation of hydro-mechanical automatic transmission – 9-speed for vehicles with a transverse power unit location and 10-speed – for vehicles with a longitudinal arrangement. Now both gearboxes, as they say, on the way. Among the models GM’s was the first Chevrolet Camaro ZL1 will received 10-speed automatic, while Ford first offered the gearbox to the extreme pickup F-150 Raptor.
Recently it was reported that GM plans to continue the widespread adoption of the 10-speed assembly, as reported by Mark Reuss, GM’s development director. At least eight key models with longitudinal arrangement of the power unit will receive the automatic gearbox before the end of 2018. Model list is not announced, but the main candidate for the new gearbox is the Chevrolet Silverado pickup – the second most popular car in the US after the Ford F-Series, as well as the Cadillac Escalade, Chevrolet Suburban and Chevrolet Tahoe, are now content with a 6-speed and 8-speed automatic. However, at first 10-speed only get top performance of the aforesaid models, turn off the production of the “old” General Motors automatic transmission is not going to be, which of course, a very wise decision.
