MP2010 Transfer Case - Service Information: Overview Dodge Durango III

Scheme 1

The ITC (Integrated Transfer Case, MP2010) is a single-speed transfer case and it is used in Grand Cherokee's new Quadra- Trac I Full-Time 4-Wheel Drive System. It provides convenient full-time 4-wheel drive. The transfer case operates with an open center differential dividing engine torque 50 percent torque to the front axle and 50 of torque to the rear axle. The Brake Traction Control System, which combines standard ABS and Traction Control, provides resistance to any wheel that is slipping to allow additional torque transfer to wheels with traction.

The MP2010 single-speed transfer case provides the following benefits

1. No shift lever or driver interaction required.
2. Full-time 4-wheel drive provides smooth operation and vehicle stability under all conditions because torque is constantly being transferred.
3. Torque distribution provides traction to maintain forward motion under most conditions.
4. The Brake Traction Control System (BTCS) works in tandem with full-time 4 wheel drive. BTCS provides resistance to any wheel that is slipping to allow additional torque transfer to wheels with traction.
5. Robust design and improved sealing enhance reliability.
6. No maintenance required.

OPERATION

Full-time 4-wheel drive distributes torque to all wheels under all conditions. The transfer case center differential divides torque to the front and rear axles, while also allowing the driveshafts to rotate at different speeds to account for front and rear wheels traveling different distances while turning. Given that the drive shafts can rotate at different speeds, the vehicle can remain in full-time 4-wheel drive mode indefinitely - even on dry pavement - without threat of damage to the drivetrain. The vehicle uses Brake Traction Control to modulate the torque from one wheel to another across each axle and the transfer case.
