SPCA 2006-2011 Honda Civic 1.8L FWD – Remanufactured 5-Speed Automatic Trans

Description

Meet strict commercial fleet maintenance benchmarks with 156 lbs of dyno-certified drivetrain engineering that directs 140 horsepower through 5 computer-timed forward gear steps in the Honda SPCA Remanufactured Automatic Transmission engineered for 2006 to 2011 Civic front wheel drive sedans and coupes powered by the 1.8-liter R18A engine.

Die-cast aluminum transaxle casings house three parallel shaft gear trains that distribute driving loads without planetary gear drag. Linear pulse-width modulated shift solenoids regulate clutch fill rates to prevent harsh gear step transitions. Micro-polished separator plates stop internal circuit pressure drops across valve body channels. Dry weight measures 156 lbs without fluid. Total fluid capacity holds 6.5 quarts of genuine Honda DW-1 ATF with a 2.5-quart service drain volume circulating through 3/8-inch cooler ports.

Key Features of Honda SPCA

Independent repair shops choose to buy Honda SPCA remanufactured transmission units to cure worn linear solenoids and clutch chatter in high-mileage compact cars. Every rebuilt unit undergoes exhaustive dynamometer load testing to confirm steady line pressure and crisp shift transitions.

• Upgraded torque converter clutch lockup friction discs eliminate low-speed vehicle shudder.
• Refurbished linear shift solenoids respond within 40 milliseconds to vehicle TCM commands.
• Precision ground steel separator plates prevent cross-circuit fluid leaks under summer heat.
• High-capacity carbon friction plates withstand frequent stop-and-start urban courier routes.
• Hard-anodized valve bore sleeves halt hydraulic fluid pressure drop across main circuits.
• Remanufactured Honda SPCA internal fluid filters maintain continuous fluid filtration.
• Differential side gear sets receive dial indicator backlash checks below 0.003 inches.
• Dyno-tested transaxle test runs verify line pressure containment under full load simulation.

Civic Automatic Gear Multiplication Thresholds

Internal line pressures regulate between 125 and 142 PSI to clamp multi-disc clutch packs without slip. Forward gear reduction steps provide 2.66:1 in first, 1.53:1 in second, 1.02:1 in third, 0.72:1 in fourth, and 0.52:1 in fifth gear overdrive. Continuous duty designation supports up to 128 lb-ft continuous input torque at 4,300 RPM. External fluid cooling circuits reject 310 BTU per minute of heat energy to hold sump temperatures between 150°F and 175°F.

Front Differential Drive Axle Splines

Internal differential side gears feature 26-spline broached bores that receive front constant-velocity halfshaft drive axles. Total axle seal bore runout measures under 0.0018 inches on dial indicators to eliminate transaxle fluid leaks. An internal mechanical parking pawl locks the gear train to resist 1,350 lb-ft static torque. Aluminum bell housing faces bolt flush to R18A engine blocks.

Civic Automatic Operational Maintenance Rules

Technicians must initiate an electronic TCM adaptive relearn cycle using an OBDII diagnostic scanner before releasing the vehicle back to commercial transport routes. Fill fluid to full mark using factory-approved Honda DW-1 ATF at operating temperature. This unit is not engineered for closed-course drag strip racing, extreme rock crawling, or gross combined vehicle weights exceeding factory chassis tow limits.

• Inspect external cooler line connections and axle drive seals for fluid leaks each shift.
• Drain transaxle fluid, clean magnetic drain plugs, and refill every 30,000 miles.
• Complete a full electronic diagnostic scan tool check on solenoid circuits every 12 months.
