A604 2005-2006 Chrysler/Dodge Town & Country, Caravan & Grand Caravan 3.3L FWD – Remanufactured 4-Speed Automatic Trans

Description

A 2.84:1 first gear ratio and 160 PSI line pressure threshold channel continuous engine output through planetary gear sets during demanding municipal passenger transit and regional airport shuttle operations. Fleets install the Chrysler Caravan 3.3L Remanufactured Transmission across 2005 to 2006 minivans to secure dependable forward propulsion under heavy payloads.

Die-cast A380 aluminum casing structures provide rigid support to resist bell housing flex behind transverse 3.3L engines. Remanufactured valve bodies incorporate micro-polished separator plates with hard-anodized Sonnax sleeves that halt fluid cross-channel leakage. Frictions feature upgraded carbon-metallic plates that dissipate heat with speed into transmission fluid circuits. Physical specifications include a 172-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 Chrysler Caravan 3.3L

Fleet managers buy Chrysler Caravan 3.3L remanufactured transmission units to restore dependable electronic shifting across passenger van and municipal vehicle fleets. This remanufactured build integrates updated solenoid blocks and reinforced clutch retainers to outlast original factory standards under severe fleet service.

• 160 PSI line pressure maintains positive clutch pack clamp force under acceleration.
• 4 forward electronic gear ratios provide optimal fuel economy and highway passing performance.
• Remanufactured solenoid blocks feature updated sound-dampened valves to halt fluid leaks.
• High-energy carbon clutch friction discs resist glaze formation under stop-and-go driving.
• Furnace-brazed torque converters prevent stator fin deflection during heavy acceleration.
• Reinforced 4-pinion planetary gear carriers distribute torque across internal sun gears.
• A Chrysler Caravan 3.3L transaxle system incorporates pulse-width modulated electronic shift solenoids.
• Machined steel transfer shaft gears maintain precise backlash tolerances to eliminate whine.

Hydraulic Pressure Solenoid Calibration

Main line fluid circuits maintain between 120 and 160 PSI pump pressure to hold clutch packs without driveline slippage under heavy vehicle acceleration. Sump fluid operating temperatures stay between 155°F and 185°F to protect automatic transmission fluid integrity. The internal geartrain handles 225 lb-ft continuous input torque at 3,600 RPM under High-Mileage Transit commercial fleet service conditions. Auxiliary heat exchangers shed 22 kW of heat away from friction packs. Gear ratios provide 2.84:1 in first, 1.57:1 in second, 1.00:1 in third, and 0.69:1 in fourth overdrive.

Differential Spline Shaft Engagement

Twin front differential outputs feature 26-spline internal broaching that accepts factory Chrysler CV half-shaft stubs. An internal parking pawl mechanism holds 1,480 lb-ft holding torque on steep parking gradients to secure loaded vehicles. Mechanics must inspect drive axle seal condition and verify transaxle bell housing runout within 0.002-inch indicator tolerance.

TCM Clutch Adaptation Protocol

Electronic transmission control modules coordinate clutch-to-clutch shift timing through pulse-width solenoid modulation without mechanical bands. Note that this transmission unit is not engineered for drag strip competition, turbo conversions exceeding factory output parameters, or heavy commercial vehicle trailer towing operations.

• Check automatic transmission fluid level and fluid clarity each shift.
• Drain fluid pan and install new internal filters every 30,000 miles.
• Conduct transmission cooler backflush operations and verify line pressure every 12 months.

Commercial Warranty Crate Contents

Purchase includes a 3-Year / 100,000-Mile commercial fleet warranty for complete operational confidence. Shipments arrive in a heavy-duty wooden container holding the complete remanufactured transmission, a balanced torque converter, new differential axle seals, an updated solenoid block, an installation manual, and an ATSG dyno test verification document.
