MRMA 2002-2006 Acura RSX 2.0L FWD – Remanufactured Automatic Trans

Description

Heat-treated cast aluminum transaxle casing architecture absorbs severe front-wheel driveline torque shock while carbon-metallic friction discs manage 141 lb-ft continuous torque during demanding commercial courier service in the Acura MRMA Remanufactured Automatic Transmission engineered for 2002 to 2006 Acura RSX sports coupes running 2.0-liter K20A3 engines.

Die-cast aluminum transaxle cases house three parallel shafts that eliminate planetary gear complexity and maintain mechanical rigidity. Hard-anodized valve body bore sleeves halt internal fluid bypass, while linear shift solenoids provide precise hydraulic circuit control. The unit holds 7.0 quarts of Honda ATF DW-1 at initial fill, weighs 162 lbs dry, and features integrated 3/8-inch cooler connection ports.

Key Features of Acura MRMA

Fleet operators buy Acura MRMA remanufactured transmission transaxles to cure common third-gear clutch burn and sluggish valve body response. Dyno testing under real engine load curves validates clutch clamp pressures across all shift transitions.

• Hard-anodized valve bore sleeves eliminate internal hydraulic fluid pressure loss.
• Carbon-metallic lockup clutch plates stop torque converter shudder under moderate throttle.
• Calibrated linear shift solenoids eliminate harsh garage shifts between park and drive.
• Spin load testing proves Acura MRMA automatic transaxle hydraulic integrity.
• Micro-finished planetary reaction plates distribute heat dissipation during stoplight transit.
• Reinforced countershaft roller bearings resist deflection under continuous VTEC engine torque.
• Magnetic transmission case drain plug isolates metallic wear particles from the pump inlet.

Hydraulic Operating Thresholds Torque Limits

Main line pressure delivers 125 to 140 PSI to lock multi-disc clutch packs under full engine output. Operating sump temperatures stabilize between 165°F and 188°F via auxiliary cooler circuits rejecting 380 BTU per minute. Five forward gear steps provide 2.684:1 first, 1.534:1 second, 1.081:1 third, 0.772:1 fourth, and 0.538:1 fifth gear, managing 141 lb-ft continuous torque at 4,000 RPM.

Front Axle Fitment Spline Data

The internal differential accepts 27-spline front CV axles with high-grade fluoroelastomer oil seals preventing output leaks. The bell housing bolts flush to Acura 2.0-liter K-series engine blocks. Torque converter pilot runout holds within 0.002 inches, preventing high-RPM vibrations from reaching the passenger compartment.

Valve Body Operation Limitations

Electronic transmission control units require proper ground wire connections to execute accurate pulse-width solenoid modulation. This transaxle is not engineered for turbo drag racing or exceeding factory gross vehicle weight ratings. Strict maintenance intervals protect hydraulic control valves.

• Inspect fluid level on the indicator dipstick every 50 hours of operation.
• Drain and replace automatic transmission fluid every 30,000 miles.
• Inspect linear shift solenoid screens for debris accumulation every 12 months.

Commercial Warranty Crate Inventory

Protected by a 3-Year / 100,000-Mile commercial fleet warranty, this transaxle ships inside a high-density molded crate. Package contents include the remanufactured transaxle unit, precision balanced torque converter, cooler line washers, vehicle-specific installation guide, and dynamometer verification test sheet.
