A604 1997 Chrysler/Dodge Town & Country/Grand Caravan 3.8L AWD/4WD – Remanufactured 4-Speed Automatic Trans

Description

Across severe ten-hour winter transit shifts of icy road conditions, this all-wheel-drive transaxle maintains hydraulic lockup and 165 PSI line pressure behind high-output 3.8L V6 minivan engines. Fleets install the Chrysler Grand Caravan AWD Transmission in 1997 all-wheel-drive passenger minivans to prevent loss of traction and secure uninterrupted passenger service.

A reinforced A380 die-cast aluminum transaxle case features an integrated transfer extension housing designed to support all-wheel-drive power transfer units. The rebuilt valve body includes hard-anodized Sonnax sleeves in high-wear bore channels to halt internal hydraulic fluid loss. Upgraded carbon-metallic friction discs dissipate operational heat across steel reaction plates. Hardware parameters include an empty dry weight of 195 pounds without torque converter, an 8.9-quart ATF+4 fluid capacity, and standard 5/16-inch inverted flare cooler ports.

Key Features of Grand Caravan AWD

Commercial fleets buy Grand Caravan AWD remanufactured transmission packages to conquer severe winter weather without driveline slippage. This remanufactured unit contains reinforced internal components and precision gear sets engineered to handle dual-axle torque distribution under demanding fleet conditions.

• 165 PSI line pressure holds friction plates firm under all-wheel-drive torque transfer.
• 4 forward electronic gear ratios optimize pulling power across slick municipal road surfaces.
• Hard-anodized valve bore sleeves halt hydraulic fluid cross-leaks inside the body.
• Reinforced power transfer unit drive splines resist mechanical wear under heavy acceleration.
• Balanced lockup torque converters prevent driveline shudder at highway cruising speeds.
• High-displacement fluid pumps maintain stable hydraulic line pressure across all temperatures.
• A Grand Caravan AWD transmission package incorporates updated electronic shift solenoid packs.
• Heavy-duty planetary gear carriers distribute drive torque across four internal pinions.

Hydraulic Pressures Transfer Ratios

Main line fluid circuits regulate between 125 and 165 PSI pump pressure to clamp clutch packs without slip under heavy load conditions. Transmission fluid sump temperatures remain within an optimal 155°F to 185°F corridor to safeguard fluid viscosity. The geartrain withstands 240 lb-ft continuous input torque at 3,600 RPM under High-Mileage Transit all-wheel-drive fleet service conditions. Auxiliary cooler circuits shed 23 kW of heat 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.

Transfer Unit Spline Interface

An extended output shaft features precision-broached splines designed to connect straight with the factory all-wheel-drive power transfer unit. The internal park lock mechanism provides 1,480 lb-ft holding torque to secure loaded minivans on steep inclines. Technicians must check transfer unit seal condition and verify power transfer alignment within 0.002-inch total indicator runout.

AWD Shift Adaptation Protocol

Electronic transmission control modules coordinate clutch-to-clutch shifts through pulse-width solenoid modulation across both drive axles to prevent tire spin. Note that this all-wheel-drive transaxle is not engineered for rock crawling buggies, track racing, or vehicle gross combined weights exceeding manufacturer chassis limits.

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

Fleet Warranty Shipping Container

Every unit purchase 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 all-wheel-drive transaxle, a balanced torque converter, new transfer unit seals, an updated solenoid block, and an ATSG dyno test certificate.
