GM plans to release its revamped lineup of trucks next year as 2014 models, and it appears that the American automaker won’t be equipping them with eight-speed automatic transmissions – at least not yet.
While the competition, such as Ram, has turned to offering an eight-speed, according to GMInsideNews, GM’s eight-speed automatic transmission is not quite yet ready, and might not come for another couple of years when the trucks receive a mid-cycle upgrade. This is similar to what happened back in 2007, when GM launched revamped models of its truck lineup with four-speed automatic transmissions.
Both the 2014 Silverado and Sierra will launch with six-speed automatic transmissions only, but are the same units that are available as an option on the current models. It is expected that GM’s eight-speed transmission will be developed as part of its Hydra-Matic automatic transmission lineup.
