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.

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.

ATF approved to MB 236.10, MB 236.12, such as Shell ATF 3403/M-115, Fuchs/Shell ATF 3353, or equivalent.

Mopar® p/n 05127382AA (1 quart)

Drain/Fill plug torque: 16-21 ft.-Lbs.

The MP3010 is a single speed transfer case which provides convenient full-time all-wheel-drive. No driver interaction is required. The DTCM module governs the torque split between the front and rear axle. Driving down a straight line on a dry surface the transfer case sends 47 percent of the torque to the front axle and 53 percent of torque to the rear axle.

This four-wheel drive (4WD) system allows front and rear wheels to rotate at different speeds when required by the road condition or road surface.

Operation

Normal All-Wheel Drive allows front and rear wheels to rotate at different speeds on all road surfaces. The “SVC 4WD” warning light monitors the electric shift 4WD system. If this light remains on after engine start up or illuminates during driving, it means that the 4WD system is not functioning properly and that service is required.

Proper operation of all-wheel drive vehicles depends on tires of equal size, type and circumference on each wheel. Any difference in tire size can cause damage to the transfer case.

The DTCM (Drive Train Control Module) is an electronic module that controls the shifting of the 4WD “Active on Demand” MP3010 single speed transfer case.

Mopar^® ATF +4, type 9602.
p/n 05013457AA (1 quart)
p/n 05013458AA (1 gallon)

Drain/Fill plug torque: 15-25 ft.-Lbs.

The Select-Trac® II is the MP3023 two-speed, on-demand, active four-wheel drive transfer case that provides optimum traction for a wide range of conditions, while maximizing driver convenience. When operating in 4WD Auto mode, this sophisticated system anticipates and prevents slip by redirecting torque as necessary.

For added traction capability when traversing steep grades, rough terrain or extremely poor traction surfaces, the transfer case includes a 4WD Low mode. This second speed gear multiplies engine torque 2.72 times and locks the clutch pack for maximum traction.

Electric shifting between 4WD AUTO and 4WD Low is effected with a console-mounted switch. A pushpin button is used to shift to Neutral mode.

Operation

Controls for the MP3023 transfer case active clutch (torque biasing device) are located in the Drive Train Control Module (DTCM) and communicated on the Controller Area Network (CAN) C bus. The DTCM monitors multiple vehicle sensors to anticipate conditions which may result in wheel slip or reduced performance and preemptively adjusts torque split to front and rear axles as needed.

The DTCM also compares wheel speeds at the front and rear axles to detect wheel slippage. A complete vehicle dynamics model, or algorithm, calculates slip at each tire for given vehicle-operating conditions. When wheel slip is detected, pressure applied to the transfer case clutch pack can be increased or decreased to apply increased torque to the axle with higher traction.

The transfer case operates in active full-time four-wheel drive (4WD AUTO) unless the driver chooses 4WD Low, or Neutral.

The electronically controlled wet clutch pack uses an electric motor to actuate an internal gear train, clutch cam, and low range barrel cam. The clutch cam actuates the clutch levers that apply normal force to the multi-disc wet clutch pack. The clutch discs are alternately splined to the front and rear drive shafts. When normal force is applied to this clutch pack, torque is transferred to equalize speed differences between front and rear axles.

Transfer of torque from one wheel to the other on an axle is accomplished by using Brake Traction Control. Under the right conditions the vehicle can be driven by just one wheel.

Standard Electronic Stability Program (ESP) works with the four-wheel drive system to enhance traction and control through three new features: Hill Descent, Hill Start Assist and Trailer Sway Control.

CAUTION:
You or others can be badly burned by hot engine coolant/anti-freeze or steam from your radiator. If you see or hear steam coming from under the hood, don't open the hood until the radiator has had time to cool. Never try to open a cooling system pressure cap when the radiator or coolant bottle is hot.

Engine Coolant Checks
Check engine coolant/anti-freeze protection every 12 months (before the onset of freezing weather, where applicable). If engine coolant/anti-freeze is dirty or rusty in appearance, the system should be drained, flushed and refilled with fresh engine coolant/anti-freeze.

The recommended mixture is 50/50 ethylene-glycol and water. Never use pure antifreeze.

The use of aluminum cylinder blocks, cylinder heads, and water pumps requires special corrosion protection. Mopar® Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769), or the equivalent ethylene-glycol base coolant with organic corrosion inhibitors (called HOAT, for Hybrid Organic Additive Technology) is recommended. This coolant offers the best engine cooling without corrosion when mixed with 50% ethylene-glycol and 50% distilled water to obtain a freeze point of -37°C (-35°F). If it loses color (red/orange) or becomes contaminated, drain, flush, and replace with fresh properly mixed coolant solution.

Notes:

Avoid non-HOAT mixtures, such as Prestone 50/50, that claim they can be used in vehicles of "all makes, all models".

Antifreeze mixture must always be at least 44%, all climates year round. Maximum protection (-90d) is provided with a 68% mixture protection.

Do not change the thermostat for summer or winter operation. If replacement is ever necessary, install ONLY the correct type thermostat. Other designs may result in unsatisfactory cooling performance, poor gas mileage, and increased emissions.

CAUTION: Use of Propylene-Glycol based coolants is not recommended, as they provide less freeze protection and less corrosion protection.

CAUTION: Mopar® Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769) may not be mixed with any other type of antifreeze. Mixing of coolants other than specified (non-HOAT or other HOAT), may result in engine damage that may not be covered under the new vehicle warranty, and decreased corrosion protection.

CAUTION: Do not use coolant additives that are claimed to improve engine cooling.

Use only the best quality fuel with a calculated Cetane Index of 50 or higher. In addition, the manufacturer recommends using diesel fuel with a sulfur content of less than 350 ppm.

Gasoline:

NOTE: DO NOT use gasolines containing Methanol or E85 Ethanol. Use of these blends may result in starting and driveability problems and may damage critical fuel system components.

87 octane Regular unleaded
(3.7L and 5.7L)

89 octane Mid-grade unleaded
(5.7 V8 Hemi, recommended for maximum performance)

91 octane Premium (R+M)/2 recommended
(6.4L V8 Hemi)

NOTE: The use of Premium gasoline is NOT recommended for the 3.8L or 5.7L engines. Under normal conditions, the use of Premium gasoline will not provide a benefit over high quality Regular and Mid-grade gasoline, and in some circumstances may result in poorer performance.

(If not replaced at first interval, inspect again each additional 12,000 mi./12 mo.)

WARNING: 12mm SPARK PLUGS MUST NOT BE OVER-TORQUED. The 3.6L Pentastar engine is the first Chrysler engine to use 12mm spark plugs. With the introduction of this smaller spark plug is a concern that can occur usually not seen with larger 14mm plugs. When the smaller 12mm spark plugs are over-torqued, the metal shell stretches, resulting in improper heat transfer from the ceramic through the shell. This in turn can cause engine damage, due to pre-ignition. With a torque wrench, tighten the 12mm spark plugs to 13 ft. lbs. (17.5 N·m).
