B7WA 2002-2003 Acura TL 3.2L FWD – Remanufactured 5-Speed Automatic Trans

Description

Sustaining 260 horsepower through 232 lb-ft of torque near 6,500 RPM demands upgraded clutch oil circuits and 142 PSI line pressure. The Acura TL B7WA Remanufactured Transmission fits 2002 to 2003 Acura TL Type-S 3.2-liter front-wheel sport platforms. Redesigned third-gear clutch feeds and high-temperature carbon frictions stop ratio flare during repeated full-throttle highway merges.

Die-cast A380 aluminum casing structures protect five-speed constant-mesh gear shafts, multi-disc clutch drums, and heavy-duty differential gears. Internal lubrication bypass kits redirect cooler fluid directly to high-heat clutch packs. Outfitted with 3/8-inch inverted flare cooler ports, this 180-pound five-speed unit holds 8.0 quarts of synthetic fluid and mounts straight to subframe points without sheet metal alteration.

Key Features of Acura TL B7WA

Performance repair centers that buy Acura TL B7WA automatic transmission packages acquire dyno-tested hardware configured for high-output Type-S V6 engines. Advanced fluid circuit engineering guarantees sustained hydraulic pressure during high-rpm gear changes.

• Patented auxiliary lube modifications channel pressurized fluid directly into the third-gear clutch drum cavity
• Sonnax hard-anodized pressure regulator sleeves eliminate internal fluid pressure drops inside the valve block
• Direct pulse-width shift solenoids react in 38 milliseconds to provide positive gear transitions
• Balanced torque converters feature furnace-brazed turbine fins that resist cavitation under heavy pulling
• Carburized helical gear sets distribute tooth contact stress during rapid stop-and-go driving cycles
• Precision-ground steel reaction plates resist heat warping under extreme passenger payloads
• Remanufactured B7WA Type-S valve bodies pass comprehensive vacuum decay testing on each circuit
• High-temperature fluoroelastomer axle seals protect against transmission oil weeping past drive hubs

High RPM Hydraulic Thresholds

Operating line pressures range from 55 PSI idle pressure up to 142 PSI under maximum engine load. Continuous input torque ratings handle 232 lb-ft at 4,800 RPM in severe commercial fleet service. Internal mechanical gear ratios offer 2.56:1 first, 1.55:1 second, 1.02:1 third, 0.73:1 fourth, and 0.52:1 fifth overdrive. Auxiliary fluid coolers dissipate 21 kW of heat, holding operating temperatures between 165°F and 188°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.

TCM Adaptive Relearn Sequence

Technicians must initiate diagnostic TCM adaptive shift programming after installation to ensure smooth clutch engagement profiles. This transmission unit is not engineered for competitive track racing, extreme vehicle speed runs, or towing trailers exceeding manufacturer gross vehicle weight ratings.

• Inspect fluid level and wipe metallic particles from the drain plug every 30,000 miles
• Drain fluid sump and add fresh synthetic transmission oil every 12 months
• Flush the transmission cooling circuit and inspect all line connections every 24 months

Commercial Warranty Crate Manifest

Supplied with a comprehensive 3-Year / 100,000-Mile commercial fleet warranty, this drivetrain delivers verified commercial durability. The heavy shipping box contains the remanufactured transmission unit, balanced torque converter, replacement cooler line crush washers, detailed installation manual, and dyno test printout.
