According to Freightliner, the combination of the 122SD with Allison’s vocational transmissions is ideal for tough off-road and oil field applications. Better performance comes from such features as 2nd reverse, which offers a second ‘deep reverse’ in addition to the standard gear. With greater startability as well, less torque is required to launch and go.
Both automatic transmissions are available on trucks powered by Detroit DD13, DD15, and DD16 and Cummins ISX heavy-duty engines.
As well as the new transmission options, under-the-passenger-seat battery mounting is now available for all 122SD day- and sleeper-cab configurations. This option should please body builders by freeing up valuable rail space.
The 122SD is suitable for oversize hauling, specialty hauling, oil/gas field service, construction, towing/recovery, and vocational on-highway applications.
