This video explores the use of the lego technic "smoothly switching 2 speed automatic gearbox" inside of a test car to see how well it works to climb up a ramp.
The gearing ratio of the 2nd gear of the 2 speed automatic gearbox can be set using a manual 4 speed gearbox to choose between gearing ratios relative to the first speed of 0.865, 0.775, 0.595 or 0.325.
The 2 speed automatic gearbox car is tested to see how well it drives up a steep hill, and is also compared to a lego manual gearbox version of the car to see the performance difference.
Finally the construction of the 2nd speed implementation using a differential is compared to a basic construction for the same gearing ratio by measuring their torque output by pulling a set of rubber bands and measuring the overall force generated.
