Introduction: How to Make an Easy Customisable Lego Transmission Part 1

This transmission set up is my own design and can be use in most Lego technic creations. I find it very cool and realistic so if you want to show of your mechanical and Lego skill I recommend this

Step 1: Parts Needed

Two 10cm rods, Three 8cm rods, Two 6.5cm rods and One grey 5.5cm rod. Three 13 holed long brick but I only have one so I am improvising. Two 2 by 10 bricks. A power function battery and small motor. And I'm sorry but I don't know what the other Lego pieces are called but all pieces will be show in the photos above.

Step 2: The Base

Step 3: The Gear Changer

For step Three use the large rods. This transmission does not have reverse because the motor does so I don't see the point of adding it but if you would like to add it, please do. This does have neutral but it needs to be adjusted in hight of the gear changer.

Step 4: Finished!!!

Congratulations you have just made manual transmission that can be changed into automatic with another motor but I currently can't show you how to do it due to money and I can't show you part two yet due to money but if you know how to finish this, go ahead, and please customize it however you wish and send me feedback and photos of your transmission. Thanks heaps!! Please follow my you tube account. https://m.youtube.com/channel/UCojmhrYpgwhhsJOwcwSsgvg . In part 2 i will show you how to make the out put shaft and maybe i might show you how to add more gears.

How can you plug up wheels to it? The output slides across, so that would mean that the wheels would be going back and front across the car. The same problem would show on a stationary machine.

I think you're supposed to slide the "output stage" across the gearbox to change the gearing ratio.

The actual rotating output would be the shaft with the rounded black gears on it.

if you use a longer connecting rod in stage 3, picture 6, you could mount the wheels right on the ends of the "output shaft"

I knew that the sliding black-geared bar was the output, but I was simply pointing out that since it slides back and forth, that would mean that when you put wheels on the output shaft, they would move forward and backward relative to the vehicle whenever you change the speed of the transmission.

There is also the problem of if you could plug up wheels to it, because in the last picture you can see that there is a perpendicular rod going right in front and behind of that output bar. But for this problem, you can move the outer pieces in pic 5 to the edges of the yellow rods, make the output come out in the center, use something else for the handle added in pic 8, switch the long bars in pic 3 for two halves, and make these bars able to slide instead of being stationary. You could also make everything much easier by just connecting the motor to the sliding output with two more gears, and fitting the use-to-be input with wheels.

This is only part 1, in part 2 I show you how to do the out put shaft. if you have build it then i can tell you how to do the output shaft. but thanks for your feedback and hope to get back to you later.
