A crashbox transmission is one that has no synchronizers to prevent
grinding when changing gears like what happens when you put a car
tranny in reverse whilst moving (I know some new cars have rev synchros)
You have to be a much better driver to drive one of these. You need to
double-clutch every up and down shift.
Doulbe clutching (going up on all gears except 5th on a CCKW) involves
stopping in neutral and letting the clutch up with the engine at idle to
slow
the gears down in the tranny. You then step on the clutch and move the
shifter
from neutral to the next higher gear. On Down shifting, you stop in neutral
and let the clutch out and give it gas to speed up the gears before stepping
on
the clutch and then going from neutral to the lower gear.
A Dodge, Ford or Chevy crashbox transmission is MUCH more difficult
to shift than a CCKW for example that has a constant mesh transmission.
With the Dodge etc transmission, you have gears with say 20 teeth trying
to engage another gear with say 15 teeth. If you mis-match the speeds, it
lets you know in no uncertain terms....!
With the constant mesh. there are dog-clutches with about 5-6 teeth that
do the connections. The gears are in constant-mesh all the time.
Remember: Real men double-clutch....
