A604 1996-1998 Chrysler/Dodge Cirrus, Sebring, Avenger FWD – Remanufactured 4-Speed Automatic Trans

Description

Command a 215 lb-ft torque ceiling and 0.69:1 overdrive cruising ratio within a controlled 155°F to 185°F thermal stability corridor while operating passenger sedans across demanding commercial fleet routes. Fleets install the Cirrus Sebring A604 Remanufactured Transmission in 1996 to 1998 Chrysler and Dodge front-wheel-drive cars to prevent shift flare and protect vehicle uptime.

A reinforced A380 die-cast aluminum transmission case protects rotating geartrains against torsional deflection under load. The remanufactured valve body utilizes hard-anodized Sonnax sleeves in wear-prone hydraulic bores to eliminate internal pressure leaks. Friction components incorporate high-energy carbon composite materials that dissipate heat into transmission fluid with speed. Casing dimensions include a 170-pound dry weight without torque converter, an 8.9-quart ATF+4 fluid capacity, and 5/16-inch inverted flare cooler connections.

Key Features of Cirrus Sebring A604

Fleet operators buy Cirrus Sebring A604 remanufactured transmission units to restore smooth electronic shifting across corporate sedan and rental car fleets. Every remanufactured build incorporates upgraded solenoid blocks and reinforced clutch retainers to outlast original factory specifications under severe fleet service.

• 155 PSI line pressure maintains clutch plate clamping force under heavy engine acceleration.
• 4 forward gear ratios provide efficient engine RPM control on highway transit runs.
• Updated solenoid blocks eliminate fluid leaks and prevent sudden limp-in mode defaults.
• High-energy carbon friction discs resist glaze formation under stop-and-go driving.
• Furnace-brazed torque converters prevent stator fin deflection during heavy acceleration.
• Reinforced planetary gear carriers distribute engine torque across four internal pinions.
• A Cirrus Sebring A604 transaxle module integrates precision pulse-width modulated shift solenoids.
• Precision-machined transfer shaft gears maintain exact backlash tolerances to eliminate whine.

Hydraulic Pressure Solenoid Thresholds

Main line fluid circuits maintain between 120 and 160 PSI pump pressure to hold clutch packs without slipping under load. Operating sump temperatures stay within a stable 155°F to 185°F range to safeguard transmission fluid integrity. The gear train withstands 215 lb-ft continuous input torque at 4,000 RPM under High-Mileage Transit service conditions. Auxiliary cooler channels dissipate 22 kW of heat through internal radiator heat exchangers. Gear ratios measure 2.84:1 in first gear, 1.57:1 in second gear, 1.00:1 in third gear, and 0.69:1 in overdrive.

Differential CV Spline Interface

Twin front differential output hubs feature 26-spline female broached connections that mate straight with factory Chrysler CV half-shaft stubs. The internal parking pawl mechanism holds up to 1,450 lb-ft holding torque on steep parking inclines. Technicians must check axle seal condition and verify bell housing runout within 0.002-inch indicator tolerance.

Electronic Shift Maintenance Guidelines

Pulse-width modulated shift solenoids communicate with the powertrain control module to coordinate clutch-to-clutch shift timing without mechanical bands. Note that this transaxle unit is not engineered for track drag strip racing, extreme aftermarket turbo modifications, or commercial cargo towing exceeding vehicle chassis ratings.

• Inspect automatic transmission fluid level and check fluid clarity each shift.
• Drain fluid pan and replace the internal pickup filter every 30,000 miles.
• Flush cooler fluid lines and verify circuit line pressure every 12 months.

Fleet Warranty Transit Manifest

Every purchase comes with 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 torque converter, new differential axle seals, an updated solenoid block, an installation manual, and an ATSG dyno test certification sheet.
