A604 1996-1999 Chrysler/Dodge Cirrus, Sebring, Avenger 2.5L FWD – Remanufactured 4-Speed Automatic Trans

Description

Prevent clutch plate glazing and electronic solenoid failure through 155 PSI fluid circuit pressure and 215 lb-ft continuous torque capacity during extreme summer commercial fleet dispatch schedules. Operators install the Chrysler Cirrus 2.5L A604 Transmission in 1996 to 1999 Chrysler and Dodge 2.5L front-wheel-drive models to eliminate harsh shifts and maintain fleet punctuality.

High-strength A380 die-cast aluminum casing walls prevent internal gear distortion under high-torque acceleration behind transverse 2.5L engines. Rebuilt valve bodies feature reamed hydraulic bores fitted with hard-anodized Sonnax sleeves to stop cross-channel fluid leakage. Carbon-metallic friction clutch discs with radial oil paths accelerate heat dissipation into fluid circuits. Installation dimensions specify an 8.9-quart ATF+4 fluid sump capacity, standard 5/16-inch inverted flare cooler ports, and an empty dry weight of 170 pounds without torque converter.

Key Features of Chrysler Cirrus 2.5L

Fleet operators buy Chrysler Cirrus 2.5L automatic transmission units to maintain continuous service across courier and corporate sedan fleets. Every remanufactured transaxle integrates updated internal components designed to outperform original factory durability standards under severe transit duty.

• 155 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 Chrysler Cirrus 2.5L transmission module utilizes calibrated pulse-width modulated solenoids.
• Reinforced planetary gear pinions resist mechanical wear under repeated throttle inputs.

Hydraulic Tolerances Gear Reduction Matrix

Regulated line pressures operate between 120 and 160 PSI across drive circuits to hold clutch discs without slipping. Sump oil temperature maintains an operating corridor of 155°F to 185°F to protect automatic transmission fluid integrity. The gear set handles 215 lb-ft continuous input torque at 4,000 RPM under High-Mileage Transit fleet conditions. Radiator tank cooler passages shed 22 kW of heat rejection from internal friction components. Mechanical gear ratios include 2.84:1 in first, 1.57:1 in second, 1.00:1 in third, and 0.69:1 in overdrive.

Front Axle Spline Connection

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 sedans on steep inclines. Technicians must check axle seal lips and verify bell housing runout within 0.002 inch.

Transaxle Adaptation Maintenance Guidelines

Electronic transmission control modules coordinate clutch-to-clutch shift timing through pulse-width solenoid modulation across all forward gears. Note that this transaxle unit is not engineered for track drag strip racing, extreme aftermarket turbo modifications, or commercial vehicle trailer towing operations.

• Inspect automatic transmission fluid level and inspect fluid color each shift.
• Drain transaxle pan and install new internal filters every 30,000 miles.
• Perform cooler line backflush procedures and test line pressure every 12 months.

Commercial Drivetrain Warranty Manifest

Every unit comes backed by 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, brand-new drive axle seals, an updated solenoid block, and an ATSG dynamometer test certificate.
