Great news for folks who like a fast-shifting automatic.
GM's ten-speed automatic transmission, which was co-developed with Ford, might not be the first transmission that comes to mind when you think "enthusiast car," but it packs plenty of performance. Quick-shifting and offering plenty of get-up-and-go, it's the automatic transmission of choice in the Ford Mustang, Chevrolet Camaro, Ford F-150 Raptor, and even the new Cadillac CT4-V and CT5-V.
Now, you can get that same performance in whatever car project you're working on - so long as it's powered by a small-block V8 from GM's fifth-generation LT family - thanks to Chevrolet Performance. Chevy is adding the slushbox to its official Performance Parts catalog as a ready-made crate transmission that's ready to go when you are.
Chevrolet Performance announced the transmission's addition to the catalog just ahead of SEMA360 - this year's online, virtual version of the annual SEMA Show, which runs from November 2-6. Chevy is calling it the SuperMatic 10L90, where "10" is the number of forward gears, "L" is for the gearbox's longitudinal configuration, and "90" refers to its torque handling capability.
The 10L90 is rated for up to 650 lb-ft, making it one of the most robust units in the ten-speed family - which is precisely why it was developed for the 650-horsepower Chevrolet Camaro ZL1. So far, that's the only production car it's been used in, although we expect it to make an appearance in the forthcoming Cadillac CT5-V Blackwing.
In crate transmission guise, the SuperMatic 10L90 will ship with a torque converter, transmission controller, and a software calibration that will enable it to communicate with whatever Gen V LT engine it's hooked up to. It's as close to plug-and-play as an automatic transmission can be, and while we appreciate a good stick-shift as much as the next bunch of car enthusiasts, we can't wait to see how people deploy it.
Ten-speed LT4-powered K5 Blazer, anyone?
