TRANSMISSION
Make/Model ..................................ZF 6WG 260 II Automatic
with manual override. The transmission assembly consists
of a torque converter close-coupled to a countershaft-type
gearbox with integral output transfer gearing. Automatic
shifting throughout the range, with kickdown feature. Lockup
action in all forward gears. A torque proportioning output
differential transmits drive permanently to front and rear
axles. This differential may be locked by the driver for use in
difficult traction conditions. Standard integral hydraulic
retarder which is automatically operated should the engine

provide valve block with additional protection from unfiltered
oil.
