1. A powertrain for a vehicle, the powertrain comprising:
a transfer case configured to couple to a transmission, the transfer case including:
a shift rod;
a piston assembly including a first piston coupled to the shift rod and a second piston selectively engageable with the first piston; and
a resilient member positioned to bias the shift rod and the first piston into a high position corresponding with a high mode of operation of the transfer case; and
an override system including:
a housing coupled to the transfer case;
a lever coupled to the housing, the lever pivotable between a first position and a second position; and
an engagement element disposed within the housing and coupled to the lever, the engagement element configured to engage the second piston in response to the lever being pivoted from the first position to the second position such that the second piston engages the first piston, thereby repositioning the first piston and the shift rod to a neutral position corresponding with a neutral mode of operation of the transfer case.
