The 2870.9 gearshift is of the mechanic type, with nine speeds and engagement of the 1
st
, 4
th
, 5
th
, 8
th
and 9
th
speeds by means of
free-ring synchronizing rings, whereas the 2
nd
, 3
rd
, 6
th
and 7
th
speeds are engaged by means of a double-cone synchronizing gear.
It consists of a front part featuring five forward gears and reverse gear and a rear part featuring two gears obtained through epicyclic
reduction gear unit (E.R.U.).
Gearshifting is performed through double H mechanical control, E.R.U. switching is through pneumatic system.
Gearbox is fitted with oil pump for lubrication.
