The Ford–GM 10-speed automatic transmission is part of a joint venture between Ford Motor Company and General Motors to design and engineer two transmissions: a longitudinal 10-speed transmission and a transverse 9-speed trans-axle. Each company manufactures its own unique version of the transmissions in its own factories.
A dog-leg gearbox or dogleg gearbox is a manual transmission shift pattern distinguished by an up-over-up shift between first and second gear. [1] The layout derives its name from a dog's hind leg, with its sharp angles. Dog leg gearboxes were replaced in most mass production vehicles by transmissions with a standard gear layout.
After each shift is completed, the engine and transmission should be operating at or near the lowest rpm speeds recommended by the manufacturers of those parts. The fastest acceleration is achieved when the truck is receiving as close as possible to maximum power throughout the entire time it is accelerating.
Automated manual transmissions can be semi-automatic or fully-automatic in operation. Several different systems to automate the clutch and/or shifting have been used over the years, but they will generally use one of the following methods of actuation for the clutch and/or shifting: hydraulic or electro-hydraulic actuation, [12] electro-mechanical, [13] pneumatic, [6] [14] [15] electromagnetic ...
Analysis shows that there are well-damped critical speed at lower speed range. Another critical speed at mode 4 is observed at 7810 rpm (130 Hz) in dangerous vicinity of nominal shaft speed, but it has 30% damping - enough to safely ignore it. Analytically computed values of eigenfrequencies as a function of the shaft's rotation speed. This ...
In this case, a rev limiter will cut engine power but it cannot prevent the engine's RPM from going beyond the redline. Perhaps the worst situation occurs when a shift is "missed". In the diagram shown, it is possible to be at high RPM and "miss" shifting from 2nd to 3rd and get 1st gear instead.

At full throttle, the Turboglide will maintain the engine RPM within a narrow (~400 rpm) span of speed around 3500-4000 rpm where the best engine output is maintained, and the car will accelerate with a strong slingshot effect to catch up as the ratios drop imperceptibly as the car speed increases along the road. The effect is very similar to ...
