Manuals rule. Automatics drool. It’s one of the core arguments among the purest of the purists. But for GM and its crown jewel, the Corvette Stingray, this dispute is not if an automatic will be offered, but rather, which automatic will be offered. Facts are facts: 63% of the 37,000-plus 2014 Corvettes sold had a six-speed automatic. The rest, well, you know what they had.More on Motortrend.com: 2015 Chevrolet Corvette Z06 Pricing Announced Such telling data is precisely why GM is sinking copious time, money, and effort into an updated eight-speed gearbox. It’s dubbed the Hydra-Matic 8L90 and it’s all GM, baby. More than 24 patents were awarded to the company’s brainiacs during its creation. It’s more efficient and more capable than the current six-speed 6L80 it replaces. But, before we get into its specifics, there’s another reason why the 8L90 came to fruition: Z06. Yes, if you haven’t heard by now, the forthcoming Z06 will have a torque-converter-packing, planetary automatic transmission option.http://image.motortrend.com/f/roadte...-in-motion.jpg
2015 Chevrolet Corvette Z06 Priced at $78,995, Convertible at $83,995 Juechter and his team turned to Kavoos Kaveh, global chief engineer for GM’s eight-speed automatic, to take on the task of building not just a gearbox for the Z06 and its crazy power, but a gearbox for the Stingray, other Corvette variants, and GM’s 6.2-liter-powered SUVs and trucks.Kaveh’s goals were simple, at least on paper: It had to be more efficient; it had to fit inside the Corvette chassis’ already extremely cozy constraints; it had to be lighter; and, if that wasn’t enough, it had to withstand all the stresses that come with the various applications.More on Automotive.com: 2015 Chevrolet Corvette Receives New Options http://image.motortrend.com/f/roadte...n-motion-1.jpg
Its updated Gen II controls include a T87 electronic control module (four times faster than Gen I), three speed sensors for more accurate multi-step shifts, and high and low variable force solenoids to better the accuracy of clutch pressure. The gearbox is eight pounds lighter due to its liberal application of magnesium and aluminum. Its piston housing and channel plate are made of the former, pricey metal; its case with bell housing, clutch pistons, input carrier, and rotating clutch housings are all aluminum. Its input carrier shell uses high-strength low-alloy steel to shed mass.
http://image.motortrend.com/f/roadte...-side-view.jpg One of the big fuel economy advantages of this car is being able to run in four-cylinder mode. DCT are not terribly compatible with AFM (Active Fuel Management). So having a torque convertor as a torsional damper in the system actually helps to use four-cylinder operation. That’s a big fuel economy enabler. Between those two factors, we, GM, elected to say ‘Ok, were going to do a planetary eight-speed transmission with a torque convertor, but we’re going to model it after DCT performance characteristics.’’ That election resulted in a very stunning, very capable, lightning-quick automatic transmission. It is gearbox that will surely have potential buyers scratching their heads, wondering if a five-, six-, or seven-speed manual is their way to go. Now, that’s saying something.
