Lego 4x4 Trial Truck With 2-Speed Automatic Transmission

[TheMindstormsPodcast]

I'm surprised at how well that works

[TheLightlessDawn]

This is very well done and good work! But would it be possible to make the transition between gears smoother?

[MrNumbskull]

A very good transmission you have here! But I was wondering, is it possible to make a 2 speed auto transmission without using pneumatics or any sort of differential (because I don't have them) and I don't have another remote and receiver to make an RC transmission.

Make another one based on engine load rather than torque like a real automatic transmission

Can i build the transmission with only one small pneumatic piston or with two big pneumatic piston.

[salkinger]

OK very good. Because I have only one small piston.
