both my parents are truck drivers. wish i could buy it for my pops, hed appreciate it

 

i drive a truck as well... that is awesome.

 

ifthat should be in someones drivway next to this http://minneapolis.craigslist.org/car/384585171.html

 

they should have used a diesel and a million gear transmission GRRRR SHHHH GR GR GRRRRRRRRR SHHHH GR GR GR GRRRRRRR SHHHHH.

speaking of which how do you drive those trucks with like 16 gears? it's like a second gearset behind the main one right?

 

1/2 scale

Looks nice except the interior. Could have done it a better.

 

That thing definitely needs a 12 valve Cummins pushing 60psi and a six speed.

Pretty sweet though

 

your dumb. but to answer your question you actually split each gear in half. so an eighteen speed would essentially be a 9 speed cut in half. To shift into the "high part" of a gear you pull or push a lever on the stick shift that activates an air cylinder that pushes a seperate part of the transmission into 2 gears. This seperate part of the transmission is what puts your gear into a "high" or a "low" ratio.

 

 

and your dumb also

think of two gear boxes

4 speed then a 3 speed.

13 speed =
SL......super low
Underdrive 1-4
Normal 1-4
Overdrive 1-4

thumb selector on top of shifter in L, go thru 1-2-3-4, then back to 1 and fliping the thumb selector to normal, 1-2-3-4, then back to 1 and overdrive 1-2-3-4.......

18 speed would be 6x3, normally L6 and N1 are the same, just saves wear and tear on the gear reduction gearbox, usually used on heavy duty trucks.

Nowadays most are 7 speeds since better injection setups, Big Orange is buying auotmatics for the newer drivers, easier to train, but limits the drivers from jumping ship after one year since they don't have and gear jamming exp.

oh yeah...........NO ------- SYNCHROS!!!!!!!

Now you wanna see a work of tranny art, look into a Road Ranger (sp) tranny. No clutch shifting but if you miss a gear you have to pull over and start from low again.
