Algodoo

Here is my 3rd attempt at making a transmission. It is based off of the one found in my marauder, but this one is more improved.

It features:
-5 speeds + reverse
-A torque converter/clutch to adjust shifting strength
-Neutral gear

I made it big because it doesn't work as well if its small, and makes tuning it harder etc. It also weighs a lot. If you minimal power loss, remove the reverse unit from the gearbox. The reason i went for friction discs and not those gears with circle teeth, is because friction discs can work at higher rpms.
