Reports and tips that General Motors has been working on a family of in-house eight-speed automatic transmissions have been circulating for years, but it seems that we may all finally see them as soon as next year. And it’s about time, because considering the competition, they’re overdue. However, the eight-speeds that will be built in-house reportedly still need more time to develop.
To borrow some allotment, Motor Trend reports on behalf of a source that GM has reached a short-term contract with Aisin to supply eight-speed transmission units for rear-wheel-drive vehicles. Think Cadillac ATS, new 2014 CTS, and even the new 2014 Corvette C7. We’ll throw the Chevy Camaro in there as well.
Aisin, which is partly owned by Toyota, currently manufactures two eight-speed automatic transmissions, with one capable of handling high-torque loads that are found in GM’s V8 engines. Motor Trend states that the supply deal will last approximately one year, where afterwards GM will begin utilizing its own eight-speeds.
It’s not exactly clear as to whether or not these Aisin eight-speeds will be used in GM’s all-new 2014 Chevrolet Silverado and GMC Sierra launching next year, or if the supplier will offer a transverse eight-speed model for use on front-wheel-drive based vehicles like the Cadillac XTS, Buick LaCrosse, and all-new 2014 Chevrolet Impala, among much more. Stay tuned with us as we continue to provide you with updates.
Meanwhile, GM and Ford continue their joint-development of nine and ten-speed transmissions for both front-wheel-drive and rear-wheel-drive use. There are also plans for a seven-speed manual transmission, and a seven-speed dual-clutch transmission.
