B4RA 1996-2000 Honda Civic 1.6L FWD – Remanufactured 4-Speed Automatic Trans

Description

Linear electronic solenoids managing 107 lb-ft of engine torque maintain 135 PSI hydraulic pressure through dense metropolitan courier delivery grids. Built for 1996 to 2000 Honda Civic 1.6-liter front-wheel platforms, this Honda Civic B4RA Remanufactured Transmission utilizes parallel-axis gearing. Re-machined valve bores and modernized clutch frictions eliminate intermediate shift flare during rapid curb stop cycles.

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 148-pound four-speed unit holds 5.8 quarts of Honda ATF fluid and bolts flush to factory transverse engine brackets without modifications.

Key Features of Honda Civic B4RA

Delivery company supervisors who buy Honda Civic B4RA automatic transmission packages secure durable powertrain units built for continuous commercial duty. Each unit eliminates factory shift hunting by using upgraded linear hydraulic controls.

• Multi-disc clutch packs configured on parallel shafts eliminate planetary friction loss and gear whine
• Sonnax hard-anodized regulator sleeves preserve steady 135 PSI hydraulic pressure during acceleration
• Direct pulse-width shift solenoids execute ratio transitions within 38 milliseconds of computer command
• Torque converters balanced within 0.03 gram-inches eliminate cabin vibration across all speed ranges
• Case-hardened helical gear clusters distribute tooth contact stress during sudden throttle changes
• Flat-lapped separator plates maintain uniform hydraulic circuit sealing across the aluminum valve housing
• Remanufactured B4RA compact valve bodies undergo vacuum decay verification across all fluid tracts
• Durable fluoroelastomer axle seals prevent transmission fluid leakage past drive half-shafts

Parallel Axis Gear Thresholds

Operating line pressures span from 48 PSI base pressure up to 135 PSI under maximum engine acceleration. Continuous input torque ratings handle 110 lb-ft at 5,000 RPM in severe commercial fleet service. Internal mechanical gear ratios offer 2.56:1 first, 1.45:1 second, 1.00:1 third, and 0.69:1 fourth overdrive. Auxiliary fluid coolers dissipate 14 kW of heat, holding operating temperatures between 160°F and 182°F.

Front Axle Spline Interface

The internal differential provides 26-spline output hubs that engage factory CV joint axle shafts without binding. The heavy-duty park pawl gear system withstands 1,250 lb-ft of holding torque on steep parking grades. Differential output runout tolerance measures under 0.0013 inches dial indicator runout, keeping vehicle propulsion steady across all speed ranges.

Diagnostic Solenoid Inspection Protocol

Conduct a diagnostic scan tool shift solenoid verification and clean external solenoid filter screens after transmission installation. This transmission unit is not engineered for competitive track auto-racing, aftermarket turbo additions, or payloads 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

Standard Warranty Crate Contents

Every unit includes a 3-Year / 100,000-Mile commercial fleet warranty for lasting vehicle protection. The protective shipping container carries the fully remanufactured transmission unit, balanced torque converter, replacement cooler line washers, installation instructional sheet, and signed dynamometer test results.
