The GY6 engine design is a four-stroke single-cylinder in a near-horizontal orientation that is used on a number of small motorcycles or scooters made in Taiwan, China, and other southeast Asian countries. It has since become a generic technology.
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 ]
PGO is known to use a connecting rod with a smaller wristpin than the GY6 Standard. I don't know if and what other differences may exist. There are two other well known anomalies in Chinese GY6 manufacturing. First are engines made by Qianjiang (code: QJ) are known to use JOG 2-stroke transmission parts, at least in the CVT.
The 5L40-E (and similar 5L50) are a series of automatic transmissions made by General Motors.Designed for longitudinal engine configurations, the series includes 5 forward gears and is used in the GM Sigma platform vehicles from Cadillac, the Pontiac Solstice, BMW, and Holden Commodore.
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.
This transmission, like single and dual range and dual coupling hydramatics, also has the feature of split torque in the transmission, whereby in fourth (or high) gear only 40% to 50% depending on transmission—40% in Roto's case—but because of the design the coupling is only required to carry 40% of the engine torque.
This all makes wet clutches better suited for use in DCTs, and thus Ford experienced problems with models of the transmission which used dry clutch packs. Ford has faced class-action lawsuits and fraud investigations in the United States, [ 4 ] Australia [ 5 ] and Canada [ 6 ] over the PowerShift gearbox as being defective and potentially ...
The 8L 90 is the subject of a class-action lawsuit filed in December 2018 that alleges the transmission suffers from persistent "shudder" issues and that GM has known about the problems since its introduction and has failed to provide a solution, instead choosing to wait until the unit is out of warranty.
