LEGO Technic - Compact 8 Speed Sequential Gearbox

This gearbox is one of the most compact sequential gearboxes. It has in fact a 2 speed gearbox combined to a 4 speed gearbox. So there are 8 gears, but it's more compact.

Thanks to this conception, the gearbox itself is more compact, and the shift system, using the rotary changeover catches of the Bugatti Chiron is also pretty compact.

I have a question: with this gearbox it is not possible to shift from the last to the first, right?

Looks like the Bugattis on a whole other level! Well done. Are there instructions?

[RobRandomVids]

Hmm... I followed the instructions but I have an axle left over along with the third orange piece and a pin. What am I doing wrong?

Very cool edit but I'd prefer to see how it actually works.. anyway it looks really good

[oscarvilche]

I get that this is a PDF file but were can i even access it? For some reason my phone doesn't allow me to view the PDF. I really could use some help. Also are the instructions for the shifter also available on that PDF??

[jasperbayless]

I have built this... And am putting it in a MOC. Can I put my MOC on LEGO Ideas? If so, how do you want to be credited?

[adamzavodsky]

will you do a tutorial on this or a similar gearbox?
