A604 2007 Dodge Caravan 2.4L FWD – Remanufactured 4-Speed Automatic Trans

Description

Command a 175 lb-ft torque ceiling and 0.69:1 overdrive cruising ratio within a controlled 155°F to 185°F thermal stability corridor while operating commercial delivery minivans across busy metropolitan courier routes. Fleets install the Dodge Caravan 2.4L Remanufactured Transmission in 2007 models to prevent gear slippage and protect vehicle dispatch schedules.

A die-cast A380 aluminum casing with a 2.4L specific bell housing pattern maintains structural integrity behind four-cylinder EDZ engines. Remanufactured valve bodies feature reamed bores fitted with hard-anodized Sonnax sleeves to stop cross-channel fluid leakage. Carbon-metallic friction clutch discs accelerate heat dissipation into fluid circuits during constant start-stop driving. Installation specifications include a 168-pound dry weight without torque converter, an 8.9-quart ATF+4 fluid capacity, and 5/16-inch inverted flare cooler thread ports.

Key Features of Caravan 2.4L

Fleet operators buy Caravan 2.4L automatic transmission units to maintain continuous service across municipal parcel delivery vans. Every remanufactured transaxle integrates updated internal components designed to outperform original factory durability standards under severe transit duty.

• 150 PSI regulated pump pressure holds clutch discs tight under maximum acceleration.
• 4 forward gear ratios provide efficient engine RPM control across city and highway routes.
• Hard-anodized valve bore sleeves eliminate internal hydraulic pressure bypass inside the body.
• High-temperature carbon friction plates withstand thermal stress during continuous stop-and-go driving.
• Balanced lockup torque converters stop driveline shudder during high-speed cruising.
• High-displacement trochoid oil pumps maintain steady fluid volume across elevated temperatures.
• A Caravan 2.4L transmission module utilizes calibrated pulse-width modulated solenoids.
• Reinforced planetary gear pinions resist mechanical wear under repeated throttle inputs.

Hydraulic Limits Four Cylinder Calibration

Main line fluid circuits generate 115 to 155 PSI pump pressure to hold clutch packs without slipping under load. Fluid sump temperatures stay within a safe 155°F to 185°F window to prevent fluid shear. The geartrain withstands 175 lb-ft continuous input torque at 4,000 RPM under High-Mileage Transit commercial service standards. Radiator cooler circuits dissipate 20 kW of thermal energy away from rotating components. Gear ratios include 2.84:1 in first gear, 1.57:1 in second gear, 1.00:1 in third gear, and 0.69:1 in overdrive.

Front CV Axle Interface

Dual differential output hubs feature 26-spline internal broaching that mates straight with factory front CV drive axle stubs. The internal park pawl mechanism holds up to 1,450 lb-ft holding torque to hold passenger vans on steep inclines. Technicians must check axle seal lips and verify bell housing runout within 0.002 inch.

Transaxle Shift Maintenance Protocol

Pulse-width modulated shift solenoids communicate with the vehicle ECM to regulate fluid pressure and manage shift timing. This transaxle unit is not engineered for track drag strip racing, extreme aftermarket turbo modifications, or commercial trailer towing exceeding vehicle chassis limits.

• Inspect transaxle fluid level and fluid clarity on the dipstick each shift.
• Drain fluid pan and replace the internal pickup filter every 30,000 miles.
• Flush external cooler circuits and verify circuit line pressure every 12 months.

Drivetrain Warranty Shipping Container

Purchase includes a 3-Year / 100,000-Mile commercial fleet warranty for complete operational peace of mind. The heavy wooden transport container holds the complete remanufactured transaxle, a balanced lockup torque converter, new differential axle seals, an installation manual, and an ATSG dyno verification test sheet with fluid pressure graphs.
