A618 1996-1997 Dodge Ram 2500 & 3500 8.0L RWD and AWD/4WD – Remanufactured 4-Speed Automatic Trans

Description

Across ten-hour transit shifts of stop-and-go regional passenger traffic, this longitudinal front-wheel-drive transaxle maintains hydraulic lockup and 155 PSI line pressure behind 2.7L DOHC V6 engines. Fleets install the Chrysler Concorde 2.7L A606 Transmission across 1998 to 1999 models to restore smooth electronic shifting and prevent expensive road downtime.

A rigid longitudinal A380 die-cast aluminum casing houses hypoid differential gear sets engineered to support 2.7L DOHC engine torque. Remanufactured valve bodies incorporate reamed bores fitted with hard-anodized Sonnax sleeves that eliminate internal hydraulic fluid cross-leaks. Carbon-metallic friction clutch discs accelerate heat dispersion into fluid channels. Exterior hardware specifications include a 188-pound dry weight without torque converter, a 9.5-quart ATF+4 fluid capacity, and 5/16-inch inverted flare cooler thread ports.

Key Features of Concorde 2.7L A606

Fleet operators buy Concorde 2.7L A606 remanufactured transmission units to restore factory driveline refinement across passenger sedans and corporate 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 Concorde 2.7L A606 transmission module utilizes calibrated pulse-width modulated solenoids.
• Reinforced planetary gear pinions resist mechanical wear under repeated throttle inputs.

Operating Pressures Gear Reduction Matrix

Main line fluid circuits maintain between 120 and 160 PSI pump pressure to lock clutch packs without slip under load. Operating sump temperatures stay within a stable 155°F to 185°F range to safeguard transmission fluid integrity. The gear train withstands 200 lb-ft continuous input torque at 4,400 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 direct third, and 0.69:1 in overdrive.

Differential Output Hub Spline Interface

Differential output gears feature precision 26-spline female connections that mate 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 vehicles on steep grades. Mechanics must check drive axle seal condition and verify bell housing runout within 0.002 inch.

Powertrain Shift Maintenance Schedule

Pulse-width modulated shift solenoids communicate with the vehicle powertrain control module to coordinate precise gear shift sequences. Note that this transaxle unit is not engineered for track drag strip racing, extreme aftermarket turbo modifications, or commercial cargo towing exceeding vehicle gross weight ratings.

• Check transmission fluid level and inspect fluid color on dipsticks each shift.
• Drain fluid pan and replace the internal pickup filter every 30,000 miles.
• Flush radiator cooler lines and verify pump circuit pressure every 12 months.

Transit Warranty Crate Manifest

Every transaxle includes a 3-Year / 100,000-Mile commercial fleet warranty for complete operational peace of mind. The heavy wooden transit container contains the complete remanufactured transaxle, a balanced lockup torque converter, brand-new drive axle seals, an installation guide, and an ATSG dyno verification test sheet with recorded pressure graphs.
