Some simple gearboxes that I decided to share with the rest of the world. Feel free to use them, but don't forget the give me my credits. =)
About this creation
The first gearbox is extremely simple, so you can probably build just from watching the photo. It's small and compactand will fit into most Technic cars. I've used it several times in MOC's that all didn't made it onto my page.
The second one is a bit more complicated. It's a 4 speed gearbox and a bit larger than the first one. I'd recommend to use this one in the larger cars where there's a bit more room to fit the gearbox.
I think this one is the best. It's a linear gearbox with 3 speed + N. I uploaded instructions for this one. I used a variation on this gearbox in my Inferno GT.

on the first one do you need that red piece? i want to try that on a car and i don't have that part... though these are really cool!
Yeah, the red brick is really necessary to make the gearbox work right. The red brick is the one that switches the gears, by moving it left or right. Linear gearboxes don't need that piece though, so that could still be a option if you don't have that red brick!
I always dreamed about a 5 speeds + clutch lego transmission, is this it? like...I could add a receiver and change gears with motors? please come back on me for this, I m willing to invest on a new technics model to realise my dream, I already have all these parts, the red part I only used in the original model, I m VERY rusted in technics, but, I have a great solar-pneumatic-nxt, project waiting, that 5 gear system would add functions, first a vehicle, then, the robot, thank you for this, it helps!

Wow, but I don't understand how this works for the car. Sorry,,,, I never used gear boxes for my cars,,,
Well, each gearbox has 2 Technic axle joiners. 1 is for the input and the other for the output. Switching gears is done with this part:
When in centre position it is in neutral and by moving it forwards or backwards, the speed at wich the output is turning, will change. Moving it is done with this brick:
Hope it helps!
Nice gearboxes. I was impressed though when you said that the linear was the best. I only build linears because I don't that red piece (how was it called?). I once built a 5-speed linear, but was quite big. Maby half Inferno GT. And wasn't really reliable...
