8-speed automatic transmission
Who would have thought there would ever be a time when we’d be talking about great fuel economy with a high-performance car with an automatic transmission?
But these aren’t ordinary times, at least when it comes to the seventh-generation Corvette.
One of the most talked about features on the 2015 Corvette Z06 is the new high performance 8-speed automatic transmission.
It was back in May of 2011 that we first learned that GM was developing an eight-speed automatic transmission for its high performance cars. But one of the things we didn’t know was that the Hydra-Matic 8L90 would be designed from the ground up specifically to handle the more than 635 lb-ft of torque generated by the 2015 Corvette Z06.
Rumors have been going around for months that the C7 Corvette would eventually have an improved automatic transmission.
Based on a technical paper summary previewed on the Web by the Society of Automotive Engineers over the weekend, a new eight-speed automatic will be available for the Stingray, perhaps as early as the 2015 model year.
When the 2014 C7 Corvette becomes available next year, it’s widely believed that buyers of the all-new sports car will have their choice of a 7-speed manual or an 8-speed automatic. The new 8-speed automatic transmission will be built at GM’s Toledo, Ohio transmissions plant and is expected to be shared by Corvette, select Cadillacs and other models across the GM lineup. However, in a report yesterday at Motor Trend, sources said the new transmissions won’t be ready for another year, so GM has partnered with the Japanese company Aisin to provide the automatics for C7 Corvette’s first year of production.
