The 6L 50 (and similar 6L 45) is a 6-speed longitudinally-mounted automatic transmission produced by General Motors.It is very similar in design to the larger GM 6L 80 and 6L 90, and is produced at GM Powertrain plants in Toledo, Ohio; Silao, Guanajuato, Mexico; and by the independent Punch Powerglide company in Strasbourg, France.
The Hydra-Matic 6T40 and similar 6T30, 6T45, and 6T50 are transversely-mounted six speed automatic transmissions produced by General Motors.The 6T40, referred to in GM inner circles as the GF6, made its debut in the 2008 Chevrolet Malibu, available with the 2.4 L LE5 Ecotec engine making 164 horsepower (122 kW), and has since also been made available on the Chevrolet Cruze, Daewoo Tosca and ...
The police package (9C1) B-body cars featured a First Gear Block Out (FGBO) Plate on the transmission housing to prevent drivetrain damage. The shift point for first to second gear is about 43 MPH (69 km/h) while second to third gear shift point is about 83 MPH (134 km/h) assuming a 3.08:1 differential and a 5,500 RPM engine speed limit.
The "MN4" 4T40E is able to handle vehicles up to 4000 lb (1814 kg) GVWR. The final drive ratio can vary depending on the car's curb weight and3wweteeengine power output. 3.91, 3.63, 3.29, 3.05, 3.69, and 3.42 are all of the available ratios used in the 4T40 (and 4T45) transmission; Made possible by using combinations selected from 3 different sprocket combinations (32/38, 35/35, 33/37) and 2 ...

The main objective in replacing the predecessor model was to improve vehicle fuel economy with extra speeds and a wider gear span to allow the engine speed level to be lowered (downspeeding). The layout brings the ability to shift in a non-sequential manner – going from gear 8 to gear 2 in extreme situations simply by changing one shift ...
In addition, the transmission supports start-stop systems by including a spring-loaded hydraulic accumulator to engage the first-gear clutches upon restarting the engine. [6] The 8th gear ratio of the 9TXX corresponds to the 6th gear ratio of the 6T40, allowing lower engine speeds in 9th gear. [5]
