Chevy’s First 9-Speed Transmission Debuts on Malibu



Quote:
Chevrolet’s very first nine-speed transmission is finally rolling out, first debuting on the 2017 Malibu and then the 2017 Cruze Diesel and 2018 Equinox.

The new transmission is available with the 2.0-liter turbo four-cylinder 2017 Chevrolet Malibu and is said to be 3 percent more fuel efficient compared to the current six-speed automatic, netting a highway rating of 33 mpg. The new transmission also works with stop/start to increase fuel economy even more by shutting down the engine in stop-and-go traffic.

Chevrolet promises its nine-speed transmission, called the Hydra-Matic 9T50, will be refined and balanced, however, other automakers have experienced problems with their nine-speed units, mainly Fiat Chrysler Automobiles (FCA) brands like Jeep. The nine-speed automatic is generally becoming more mainstream, as it was once reserved for luxury cars like Mercedes-Benzes and Land Rovers.

Chevy’s transmission has a wider 7.6:1 overall ratio than the current transmission, which translates into a meaty first gear for brisk off-the-line acceleration and a tall final gear for low-rpm highway cruising.

'The smaller steps between the gears, compared to the six-speed, enable smooth, almost imperceptible upshifts, for excellent refinement,' said Dan Nicholson, vice president, Global Propulsion Systems. 'No matter the engine torque or vehicle speed, the 9T50 is always in the perfect gear.'

Nicholson added that the new transmission will be available on four Chevrolet models and 10 GM products by the end of next year.

Drove a rental Malibu LT last month on vacation, with the 6 speed 1.8 turbo 4 cyl. Six speeds was perfect already. Couldn't believe it was only a 1.8.

Fascinating, GM using the LOWEST brand to roll out a potentially sizable tech advance. In the old days Cady would've kidnapped that as an 8k option - stuck in an ATS or whatever their smallest model is now. I'm in to see the bugs get worked out.

So instead of sliding through 3 slushy shifts, you get to slide through 8. Kewl.

94 RMSB 170K Sat 5 years, ran for 1 of those then remained untouched for 4. Sat because it was slapped by a deer and the owners didnt want to fix it for whatever reason.
Mods, all the free good ones.
Future? Probably pull engine, reseal it, and run it a lot more. Looking to get 250k out of it. PRAYING for 300k.

We are nearing the point of a gear for every mph. I guess that would be a CVT... those suck. I want actual shifting!
