Lego today released a video showcasing the new 42110 Land Rover Defender model.

The video captions mention that it has “Lego Technic’s most sophisticated gearbox to date”, and we see 3 seemingly related features.

The first two are fairly typical levers for “hi/lo” and “?/N/R”, ie gear selection and direction.

The other is a dial labelled “+ -“:

What is this dial for?

Based on a comment found in the overview on Brickset, and that all of the others levers and their function seem to be accounted for, it seem very likely that it is the transmission gear selector.

-UPDATE BELOW-

From Brickset:

"A new transmission system has two levers for engaging high or low ratios and a selector for changing gear – LEGO Technic’s most sophisticated gearbox yet."

In other words, the transmission gears 1-?, rather than it's selection D/N/R and transfer case Hi/Lo. The transmission looks too complicated to just be directional switch (D/N/R) and 1 gear range switch (Hi/Lo).

I have no idea how many gears it has, or if I am even correct. It's all just speculation based on my observations. Either way the set looks amazing! I'm a sucker for vintage cars and all things 4x4.

Just confirmed from Lego.com:

Opening doors allow access to an elaborate cabin with a working steering wheel, detailed dashboard and a new-for-October-2019 transmission system with 2 levers for engaging high or low gear ratios and a selector for changing gear – the most sophisticated LEGO Technic gearbox to date! The interior also features forward-folding rear seats that give visual access to the 4-speed sequential gearbox.

So it's a 4-speed transmission, nice!

  • Wow! I didn’t think it could be anything like that due to the ease with which it appears to rotate! – James Thorpe Sep 12 at 6:22
  • @JamesThorpe - Maybe a worm gear type setup? Lego continues to amaze me with the complexity of their sets. – JohnnyB Sep 12 at 7:14
  • Could be - one of the stills you selected from the video has this orange piece in it - looks to be a way of activating the neighbouring gear lock via rotation rather than the usual reciprocation of a lever – James Thorpe Sep 12 at 7:32

    I assume it's one of these - seems it's also been in the Bugatti last year. – James Thorpe Sep 12 at 7:48
  • @JamesThorpe - I honestly didn't even know that existed. The Bugatti has yet to be squeezed into the budget. Now I'm all sorts of curious about the transmission in that thing. – JohnnyB Sep 12 at 15:15
