|   Thursday, September 11, 2014
Chevrolet has figure out its new Corvette Stingray with consisting of automatic eight-speed transmission instead of its great performance and lower emission driven followed by industry trend replaces the older charger auto six-cog into Stingray. Perhaps, just like other carmakers GM has built and designed its own unit GM8L90 named code such that it can evade its same trend used to run its shift program through ZF gearbox.

The GM box weights few kilos lighter than other outgoing units, inspite of having two more of gears in its kit stack.
This box not only match the swapping time relating to industries leading units also beats them and so it's been benchmarked in contrast with 911 PDK's of Porsche.

The engineer of GM have put an effort such that the gears can be swap by drivers itself with paddles and saves the tenth off the time 0-60mph and quarter miles. This is done by engaging clever PTM (Performance Traction Management) while in drive mode, where it automatically push and pull gears itself accordingly as and when required depending on conditions.

On track, with this box consisting of eight-speed can get shifted to its lowest gear as computer estimate that it can handle when once the downshift paddle is pulled and hold it into the corner way. While on road, it's not too low or high with gears and gives instant response once put foot down as it does not consist of twin-clutched stutter that come out through junctions.

However, this auto box with eight-speed will be set to all Corvette Stingrays models for the year 2015 specifying automatic. Moreover, the debuts of Z06 will be seen later in this year making available with same units and also adding with couple of air coolers.

The General Motors Milford said; "The traditional automatic transmission 8-speed for Corvette Stingrays and coming Z06 of Chevrolet will rival the sports cars automaker's of automatic gearbox consisting 7-speed dual clutch in Porsche 911, making it available with more bowtie valued improved fuel economy and quick shifts." Also in the year 2015, trucks will be seen with added 8-speed L86 engine, where GM used LT1 V-8 small block Corvette's 6.2L and redesigned it through modifying the version for 2014 for its SUV and large pickups.

In the first quarter year of 2015, Z06 the latest generation which will be arriving from base of Stingrays will be developing 650bhp and producing 650lb/ft of torque with other exterior upgrades and mechanical changes been done on it. The Hydra Matic-8L90 with automatic 8-speed rear-wheel drive for 2015 bows on Corvette as new technology model for coming-up year will be joining in the Valet Mode and PDR (Performance Data Recorder).

The GM new 8L90 automatic eight-speed equipped with V8 6.2 liter allows driver to concentrate on brakes and steering while turning quick in lap processes. The Z06 with 8L90 will include dual transmission coolers; one as regular Stingrays consist in hindquarters and other one on chassis underbelly laying flat. General Motors 8L90's shifts is quicker as any available units of dual clutch.
