U241E 2004 Toyota Highlander 2.4L FWD – Remanufactured 4-Speed Automatic Trans

Description

Torque converter friction plate shudder under 162 lb-ft hauling loads compromises municipal delivery deadlines until hydro-pulse calibrated solenoids and upgraded friction plates stabilize internal fluid circuits inside the Toyota U241E Remanufactured Transmission engineered for 2004 Highlander 2.4-liter front wheel drive commercial fleet crossovers.

Die-cast A380 aluminum transaxle casings house high-precision planetary gear carriers and micro-polished hydraulic separator plates. Upgraded valve body bores feature hard-anodized sleeves to halt hydraulic pressure drop under high operating temperatures. Driveline utility hardware includes an integrated front differential, 3/8-inch inverted flare cooler line ports, 8.6-quart fluid capacity for Type T-IV fluid, and a 176-pound dry unit mass.

Key Features of Toyota U241E

Municipal utility fleets buy Toyota U241E remanufactured transmission transaxles to restore butter-smooth gear changes and preserve vehicle reliability. Every internal hydraulic circuit undergoes hydro-pulse dyno testing to verify correct shift timing across all engine loads.

• Hard-anodized valve body bore sleeves prevent internal hydraulic circuit pressure leakage
• High-energy carbon-metallic clutch plates withstand continuous high-speed transit shifts without glazing
• Precision balanced furnace-brazed torque converters eliminate high-speed driveline vibration
• Pulse-width modulated solenoids respond to TCM commands within 40 milliseconds for crisp gear shifts
• Toyota U241E automatic transaxles undergo full hydro-pulse dyno cell load testing before crating
• Micro-finished planetary gear tooth profiles keep transmission operating noise to absolute minimums
• Magnetic fluid pan collectors trap microscopic steel particulate to extend hydraulic valve life

Mechanical Gear Ratios Thermal Thresholds

Built for demanding utility fleet transit, this four-speed automatic transaxle manages 162 lb-ft continuous input torque at 4,000 RPM under 160 to 215 PSI main line circuit pressure. Sump temperature holds between 160°F and 185°F under full thermal stabilization. Gear reduction ratios deliver 3.938:1 first, 2.194:1 second, 1.411:1 third, and 0.703:1 fourth overdrive, releasing 46 BTU per minute across auxiliary cooler circuits.

Differential Side Gear Spline Dimensions

Power transfers straight through internal 30-spline differential side gears machined to accept OEM constant velocity halfshafts. Output journal centerline runout measures under 0.0016 inches across all rotational test points. Precision machined axle seal bores prevent transaxle fluid seepage during sharp cornering.

Electro Hydraulic Transaxle Maintenance Protocols

Verify that transmission cooler lines remain free of internal sludge to preserve transmission fluid cooling flow. This automatic transaxle is not engineered for competition drag racing, high-boost engine tuning, or towing trailers exceeding factory vehicle gross weight limits.

• Inspect cooler line connections and casing pan seams each shift
• Drain and refill with approved Type T-IV fluid every 30,000 miles
• Inspect electronic wiring harness connectors for corrosion every 12 months

Commercial Drivetrain Protection Crate Inclusions

Guaranteed by an ironclad 3-Year / 100,000-Mile commercial fleet warranty, this gearbox package protects fleet investments. The reinforced crate encloses one remanufactured four-speed automatic transaxle, precision balanced torque converter, replacement cooler line seal washers, and an ATSG dynamometer pass document.
