A604 2009-2018 Dodge Journey 2.4L FWD – Remanufactured 4-Speed Automatic Trans

Description

Incorporating 155 PSI line pressure, an upgraded electronic solenoid block, and a 2.84:1 low gear ratio, this drivetrain propels 2.4L four-cylinder commercial crossover vehicles across demanding municipal transit schedules. Operators install the Dodge Journey 2.4L A604 Transmission in 2009 to 2018 front-wheel-drive crossovers to eliminate shift slip and preserve vehicle dispatch deadlines.

A rigid die-cast A380 aluminum casing absorbs torsional vibration generated by transverse 2.4L World Engines in crossover applications. Remanufactured valve bodies incorporate hard-anodized Sonnax sleeves in high-wear bore locations to eliminate internal pressure loss. Frictions feature heavy-duty carbon composite plates that withstand extreme heat generated during stop-and-go driving. Specifications include an empty weight of 172 pounds without torque converter, an 8.9-quart ATF+4 fluid capacity, and 5/16-inch inverted flare transaxle cooler line fittings.

Key Features of Dodge Journey 2.4L

Fleet managers buy Dodge Journey 2.4L remanufactured transmission units to restore factory driveline performance across regional transportation routes. This remanufactured drivetrain unit features reinforced internal components engineered to outlast original factory specifications under severe van service.

• 155 PSI regulated line pressure prevents clutch slip under heavy vehicle acceleration.
• 4 forward gear ratios maximize torque output from transverse 2.4L four-cylinder engines.
• Hard-anodized valve bore sleeves halt hydraulic fluid cross-leaks inside the body.
• High-energy carbon friction discs dissipate operational heat to prevent plate glaze.
• Balanced lockup torque converters eliminate driveline vibration at highway cruising speeds.
• High-output fluid pumps maintain stable hydraulic line pressure across elevated temperatures.
• A Dodge Journey 2.4L drivetrain package incorporates updated electronic shift solenoid packs.
• Reinforced planetary gear carriers distribute engine torque across four internal pinions.

Hydraulic Thresholds Journey Calibration

Main line fluid circuits regulate between 115 and 155 PSI pump pressure to hold clutch packs firm without slippage under load. Transaxle fluid sump temperatures remain within an optimal 155°F to 185°F corridor to safeguard fluid viscosity. The geartrain withstands 175 lb-ft continuous input torque at 4,000 RPM under High-Mileage Transit commercial fleet duty cycles. Auxiliary radiator cooler passages shed 20 kW of heat from internal clutch friction discs. Gear ratios measure 2.84:1 in first, 1.57:1 in second, 1.00:1 in third, and 0.69:1 in fourth overdrive.

Differential CV Axle Connection

Dual differential output hubs feature 26-spline internal broaching engineered to receive factory Chrysler CV axle stubs. The internal parking pawl gear provides 1,480 lb-ft holding torque to hold loaded passenger crossovers on steep inclines. Technicians must check axle seal lips and verify bell housing runout within 0.002-inch total indicator runout.

Solenoid Adaptation Maintenance Schedule

Calibrated pulse-width modulated solenoids respond to engine control module commands to execute positive gear shifts across varying vehicle loads. This transaxle unit is not engineered for track drag strip racing, extreme off-road use, or gross vehicle weights exceeding manufacturer crossover tow ratings.

• Inspect transaxle fluid level and fluid condition on the dipstick each shift.
• Drain fluid pan and install new internal pickup filters every 30,000 miles.
• Perform cooler line backflush procedures and test circuit line pressure every 12 months.

Fleet Warranty Documentation Manifest

Every transaxle purchase comes backed by a 3-Year / 100,000-Mile commercial fleet warranty for complete operational peace of mind. Shipments arrive in a heavy wooden transport container holding the complete remanufactured transaxle, a balanced lockup torque converter, brand-new drive axle seals, an installation manual, and an ATSG dynamometer test certificate.
