2007 TRANSFER CASE MP140 - Service Information - Nitro
With an automatic transmission, the MP 140 single-speed transfer case is used in Nitro's new Full- Time Four-
Wheel Drive System. It provides convenient full-time four-wheel drive operation and functions seamlessly with
Nitro's standard Traction Control and ESP (Electronic Stability Program) features to provide enhanced traction
and stability on low-traction surfaces. The MP designation refers to Magna Powertrain, the successor to New
Venture Gear.
The MP140 single-speed transfer case provides the following benefits:
Convenient operation: No shift lever or driver interaction required.
Smooth operation and vehicle stability under all conditions because torque is constantly being shared
among all wheels.
Traction to maintain forward motion under most conditions through 48 front/52 rear percent torque
distribution.
Enhanced traction and stability provided by the Traction Control and Electronic Stability Program (ESP)
working in tandem with full-time four-wheel-drive. Traction Control and ESP provide resistance to any
wheel that is slipping to allow additional torque transfer to wheels with traction.
Robust design and sealing for reliability.
No maintenance required.
OPERATION
TRANSFER CASE - MP140
Full-time 4-wheel drive distributes torque to all wheels under normal driving conditions. The transfer case uses
an open (unlocked) center differential to divide engine torque nearly evenly between the front and rear axles -
48 percent to the front axle and 52 percent to the rear axle. The open differential allows the front and rear drive
shafts to rotate at different speeds to account for front and rear wheels traveling different distances when
turning. Because the drive shafts can rotate at different speeds, the vehicle can remain in full-time 4-wheel drive
mode continuously - even on dry pavement - without threat of damage to the drive train. The standard-
equipment ESP, which combines ABS, Traction Control, and Electronic Roll Mitigation, enhances traction by
modulating torque among all wheels as necessary - providing resistance to any wheel that is slipping while
allowing torque to flow to the wheels with traction.
