U151E 2004-2008 Toyota Solara 3.3L FWD – Remanufactured 5-Speed Automatic Trans

Description

Prevent forward clutch pack slippage under 240 lb-ft sustained output while maintaining 180°F fluid sump stability during demanding regional transit operations using the Toyota U151E Remanufactured Transmission engineered for 2004 to 2008 Solara 3.3-liter front wheel drive coupes and convertibles.

Die-cast A380 aluminum transaxle cases 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 hardware specs feature 3/8-inch inverted flare cooler line ports, 9.3-quart fluid capacity for Type T-IV fluid, and a 184-pound dry unit mass.

Key Features of Toyota U151E

Rental vehicle operations buy Toyota U151E remanufactured transmission units to restore crisp gear changes and prevent transmission slippage during aggressive customer driving. 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 U151E 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

Dynamic Torque Transmission Pressure Bounds

Built for demanding fleet transit, this five-speed automatic transaxle manages 240 lb-ft continuous input torque at 3,600 RPM under 165 to 220 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, 1.020:1 fourth, and 0.703:1 fifth overdrive, releasing 50 BTU per minute across auxiliary cooler circuits.

Differential Output Hub Spline Interface

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.

Electronic Solenoid Maintenance Service Schedule

Conduct transmission computer adaptation relearn procedures following installation to ensure optimal shift timing. 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

Fleet Crate Package Warranty Inclusion

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