what's new? Following the industry trend - driven by ever lower emissions and greater performance - Chevy has slotted a new eight-speed automatic transmission in place of the old six-cog auto changer into the Stingray (and its heavy V8 trucks).But shunning the same trend to use a ZF gearbox and just run their own shift program

So, what's new?

Following the industry trend - driven by ever lower emissions and greater performance - Chevy has slotted a new eight-speed automatic transmission in place of the old six-cog auto changer into the Stingray (and its heavy V8 trucks).

But shunning the same trend to use a ZF gearbox and just run their own shift program, like half a dozen carmakers, GM has actually designed and built this unit - codenamed GM 8L90 - itself. And it's a pretty tidy piece of kit, too. Despite having two more gears in the stack, the new box is several kilos lighter than the outgoing unit.

But I'll bet its change times aren't a patch on the best double clutch boxes...
