Notice: The orange shifters have to be aligned exactly as shown for the gears to be traversed correctly!
This sequential gearbox has 10 gears + park + reverse. The gear ratios are traversed sequentially by turning the yellow gear near the engine. To be connected with a sequential gear changed as seen in the 1:8 super cars, such as the Porsche 911 GT3 RS, Bugatti Chiron and Lamborghini Sian. The gearbox replicates the 10 speed transmissions found in high powered FR (RWD) cars, such as the latest Ford Mustang and Lexus LC500.
The gear ratios are computed between the input and output tan 20 tooth gears near the engine and rear differential, respectively. Not included in the ratios are the differential and engine gearings. The gear ratios can be changed by turning the center differential and using a 16 tooth gear instead of the 8 tooth gear to the output axle.
This gearbox is for demonstration purposes. You can power it from the motor, but not from the wheels. This is due to the friction caused by the LEGO parts - see the video. It is not well suited for RC applications due to the high torque combined with low speed of some of the axles. Using a motor for demonstrating the gears is perfectly fine.
For Studio 2.0, these parts should be saved in C:\Program Files\Studio 2.0\ldraw\Custom Parts\Parts on Windows and Applications/Studio 2.0/ldraw/Custom Parts/Parts on MAC. See this video for a guide of how to set it up in Studio 2.0 and use their rendering engine.
