SP5A 2009-2013 Honda Fit 1.5L FWD – Remanufactured 5-Speed Automatic Trans

Description

Across grueling 12-hour urban delivery shifts demanding 250 stop-and-go curb drops, internal multi-disc clutch packs hold 135 PSI clamp pressure without slip inside the Honda SP5A Remanufactured Automatic Transmission engineered for 2009 to 2013 Fit front wheel drive vehicles powered by the 1.5-liter i-VTEC four-cylinder engine.

Three-shaft parallel gear train architecture housed inside high-strength die-cast aluminum casings minimizes rotational friction while delivering smooth gear selection. Precision-machined valve bodies receive hard-anodized sleeves to stop hydraulic cross-leaks under elevated operating temperatures. High-energy carbon friction discs pair with steel reaction plates to provide crisp gear lockup. Total dry weight registers 145 lbs without fluid. Sump capacity holds 6.4 quarts of Honda DW-1 ATF with external cooling connections through 5/16-inch barbed ports.

Key Features of Honda SP5A

Courier fleet managers choose to buy Honda SP5A remanufactured transmission units to eliminate delayed forward gear engagement and converter clutch shudder. Comprehensive remanufacturing brings all valve body bores and clutch clearances back to original factory specifications for dependable commercial operation.

• Precision-machined valve bodies halt hydraulic fluid bypass to preserve high line pressures.
• Remanufactured torque converters feature balanced turbine hubs to prevent driveline shudder.
• Refurbished electromagnetic shift solenoids actuate reliably under severe summer operating heat.
• High-capacity carbon clutch friction packs replace standard linings for extended service life.
• Parallel shaft helical gearsets maintain quiet gear tooth mesh across all speed ranges.
• Upgraded differential side gears distribute drive axle torque in balance without vibration.
• Dyno-tested Honda SP5A valve bodies maintain line pressure without internal fluid bypass.
• Viton internal shaft seals prevent hydraulic cross-circuit leakage past rotating drums.

Five-Speed Automatic Gear Ratios Calibration

Internal line circuits maintain operating pressures between 120 and 138 PSI to clamp friction elements under maximum cargo payloads. Gear reduction ratios span 2.99:1 in first, 1.68:1 in second, 1.07:1 in third, 0.76:1 in fourth, and 0.55:1 in fifth overdrive. Rated for 106 lb-ft continuous input torque at 4,800 RPM. Auxiliary transmission fluid coolers reject 290 BTU per minute of heat energy to hold sump temperatures between 150°F and 175°F.

Axle Differential Spline Interface Geometry

Internal differential side gears incorporate 26-spline broached profiles to accept front constant-velocity axle joints. Shaft runout measures under 0.0018 inches to protect axle drive seals from premature leakage. The internal parking pawl gear provides 1,200 lb-ft holding force on steep urban loading docks. Bell housing mount holes match factory L15A engine block bolt patterns.

Electronic Shift Calibration Maintenance Rules

Perform an electronic TCM calibration reset using an OBDII diagnostic tool before driving the vehicle under commercial loads. Check fluid level with the transmission warm and the engine shut off on level ground. 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 cooler pipe connections and halfshaft axle seals for fluid weeping each shift.
• Drain transaxle fluid and clean magnetic drain plugs every 30,000 miles.
• Perform full electronic solenoid circuit resistance and cycle checks every 12 months.

Commercial Automatic Shipping Crate Manifest
