MJBA 2006-2008 Acura RL 3.5L AWD/4WD – Remanufactured 5-Speed Automatic Trans

Description

Torque converter clutch friction glazing and secondary gear hydraulic circuit pressure drop under 256 lb-ft torque loads compromise executive transport schedules until steel valve sleeves and balanced converters restore positive lockup inside this Acura MJBA Remanufactured Automatic Transaxle built for 2006 to 2008 Acura RL all-wheel-drive sedans with 3.5-liter V6 engines.

A high-tensile die-cast aluminum transaxle case encapsulates an advanced three-shaft design integrated with a mechanical transfer drive pinion. Re-machined valve bodies incorporate steel sleeves to stop hydraulic fluid cross-leakage between circuit passages. Sump capacity requires 8.2 quarts of Honda ATF DW-1, dry weight measures 196 lbs, and fluid cooler lines connect via standard 3/8-inch inverted flare ports.

Key Features of Acura MJBA

Professional repair centers buy Acura MJBA remanufactured transmission systems to cure chronic torque converter shudder and delayed engagement issues. Technicians verify line pressures across every gear ratio on advanced computer dyno test stands before crating.

• Hard-anodized pressure regulator sleeves prevent pressure drops during high-temperature idling.
• High-friction clutch linings provide quick lockup without slipping under full vehicle loads.
• Computer-matched linear shift solenoids guarantee smooth forward gear progression.
• Dyno load testing proves Acura MJBA remanufactured transaxle hydraulic integrity.
• Furnace-brazed torque converter impeller fins eliminate vibration at sustained highway speeds.
• Full-flow internal fluid filters catch particulate matter before it reaches shift valves.
• Precision roller bearings maintain countershaft alignment under rapid acceleration.

Hydraulic Line Pressure Gear Ratios

Main line pump circuits generate 132 to 148 PSI to lock internal clutch discs without slippage under 256 lb-ft continuous input torque at 5,000 RPM. Sump fluid heat stays between 165°F and 190°F through vehicle heat exchangers rejecting 430 BTU per minute. Gear ratios deliver 2.520:1 first, 1.545:1 second, 1.047:1 third, 0.763:1 fourth, and 0.551:1 fifth gear for maximum highway refinement.

Differential Axle Spline Interface

Precision broached differential gears accept 30-spline CV axle stubs with dual-lip spring seals stopping fluid leaks. Bell housing flanges align flush to Honda J35A8 engine blocks using standard dowel sleeves. Converter hub dial indicator runout remains below 0.002 inches to ensure long front pump seal durability.

Hydraulic Circuit Service Procedures

Proper electrical ground connections ensure consistent pulse commands reach linear shift control solenoids. This transmission is not engineered for competitive track drifting or vehicle loads exceeding gross vehicle weight limits. Following recommended fluid service preserves valve body bores and clutch pack health.

• Check transmission fluid level via the dipstick tube every 50 hours of driving.
• Perform drain and refill using approved Honda ATF DW-1 every 30,000 miles.
• Inspect transmission cooler lines and radiator tank fittings every 12 months.
