BT38 2010-2012 Acura RDX 2.3L FWD – Remanufactured 5-Speed Automatic Trans

Description

Channeling 260 lb-ft of sudden turbo torque through 140 PSI line pressure stops clutch pack slippage across aggressive front-wheel accelerations. The Acura RDX BT38 Remanufactured Transmission supports 2010 to 2012 Acura RDX 2.3-liter front-wheel turbo crossovers. Re-machined valve bodies and reinforced multi-disc clutch packs prevent intermediate shift flare during rapid expressway merges.

Die-cast aluminum casing structures protect constant-mesh helical gear shafts, multi-disc clutch drums, and micro-finished bronze bushings. Re-machined valve bodies with hard-anodized valve bore inserts stop internal hydraulic leakage. Equipped with 3/8-inch barb cooler ports, this 176-pound five-speed unit holds 8.2 quarts of Honda DW-1 fluid and bolts flush to factory transverse engine brackets without modifications.

Key Features of Acura RDX BT38

Fleet operators looking to buy Acura RDX BT38 automatic transmission packages receive dyno-certified drivetrain units engineered to eliminate factory shift shudder. Upgraded linear solenoid circuits and re-machined clutch feed tubes maintain positive gear transitions.

• Individual clutch packs for each forward ratio eliminate planetary friction wear and parasitic gear drag
• Hard-anodized pressure regulator valve sleeves maintain constant 140 PSI hydraulic main circuit pressure
• Direct pulse-width shift solenoids execute ratio transitions within 38 milliseconds of computer command
• Dynamic computer-balanced torque converters eliminate rotational vibration through the engine flexplate
• Precision-ground helical gear teeth maintain silent mechanical mesh across all forward ratios
• Lapped separator plates guarantee absolute pressure retention across internal fluid feed tubes
• Remanufactured BT38 turbo valve bodies pass multi-stage vacuum integrity testing on each port
• Heavy-duty fluoroelastomer axle seals prevent fluid weeping past differential half-shaft collars

Turbocharged Hydraulic Operating Parameters

Main hydraulic line pressure regulates between 54 PSI at idle and 140 PSI under full turbo acceleration. Continuous input torque ratings handle 260 lb-ft at 4,500 RPM under severe commercial fleet service. Internal mechanical gear ratios measure 2.70:1 first, 1.61:1 second, 1.07:1 third, 0.77:1 fourth, and 0.53:1 fifth overdrive. Auxiliary fluid heat exchangers dissipate up to 19 kW of thermal energy, keeping fluid sump temperatures between 160°F and 185°F.

Differential Axle Spline Interface

Equalized internal differential outputs accept 28-spline front half-shaft CV joints without mechanical clearance play. The parking pawl mechanism holds 1,500 lb-ft of static driveline load on steep parking ramps. Differential output hub runout measures under 0.0013 inches dial indicator deflection, maintaining steady front-wheel rotation at sustained highway speeds.

Electronic Solenoid Calibration Steps

Perform a comprehensive shift linkage check and clear PCM adaptation parameters following transmission installation to program clutch engagement timings. This transmission unit is not engineered for track drag racing, turbo conversions exceeding 300 horsepower, or sustained trailer towing beyond vehicle chassis ratings.

• Check transmission fluid clarity and examine pan magnet cleanliness every 30,000 miles
• Drain fluid sump and replenish with approved synthetic oil every 12 months
• Flush external transmission cooler lines and clean heat exchanger fins every 24 months

Commercial Fleet Warranty Terms

Supplied with a 3-Year / 100,000-Mile commercial fleet warranty, this transmission safeguards vehicle uptime. The sealed transport container contains the remanufactured transmission unit, balanced torque converter, replacement cooler line seal washers, vehicle-specific setup guide, and verified dynamometer test printout.
