U151F 2006-2007 Toyota Highlander & Lexus RX330 3.3L AWD/4WD – Remanufactured Automatic Trans

Description

Command 215 horsepower and a relaxed 0.703:1 fifth gear overdrive ratio while holding fluid sump temperatures below 185°F across demanding regional transportation routes inside the Toyota U151F Remanufactured Transmission tailored for 2006 to 2007 Highlander and Lexus RX330 3.3-liter all wheel drive crossover vehicles.

Thick-wall die-cast aluminum housings provide structural stiffness to prevent housing deflection during all wheel drive traction events. Reconditioned valve bodies feature micro-polished separator plates and hard-anodized sleeves to prevent pressure loss. Hardware specifications feature transfer case drive splines, 3/8-inch cooler line ports, 9.8-quart fluid capacity, and an overall dry unit weight of 196 lbs.

Key Features of Toyota U151F

Regional transit operators buy Toyota U151F remanufactured transmission units to restore work vehicle mobility and eliminate transmission slip on slippery winter roads. Balanced rotating components eliminate driveline vibration across all operating speeds.

• Re-machined valve body bores with hard-anodized sleeves prevent hydraulic cross-leaks
• Carbon-composite clutch friction discs maintain high torque clamping without glazing
• Furnace-brazed torque converters provide rigid lockup across extended highway routes
• Direct-acting shift solenoids respond to TCM commands within 40 milliseconds for positive shifts
• Toyota U151F automatic gearboxes undergo rigorous spin-bench testing to check internal tolerances
• Heat-treated planetary gears handle high continuous torque without tooth surface pitting
• Heavy-duty casing seals protect internal fluid circuits from road dirt and water contamination

Dynamic Torque Transmission Pressure Bounds

Engineered for high-demand utility fleet operations, this five-speed automatic transaxle handles 222 lb-ft continuous input torque at 4,400 RPM under 170 to 225 PSI line pressure. Sump temperature runs between 165°F and 188°F across demanding haul routes. Gear reduction spreads span 3.938:1 first, 2.194:1 second, 1.411:1 third, 1.020:1 fourth, and 0.703:1 fifth overdrive, shedding 54 BTU per minute through the casing.

Transfer Drive Pinion Centerline Alignment

Drivetrain power passes through precision-broached internal transfer drive splines designed to link straight into the factory center transfer case. Output shaft runout measures under 0.0018 inches total indicator reading to prevent bearing bind. Machined adapter flanges ensure exact transfer case pilot centering.

AWD Automatic Transaxle Inspection Procedures

Ensure transmission cooler lines remain completely flushed before putting the vehicle into commercial service. This automatic all wheel drive transaxle is not engineered for heavy commercial snow plowing, off-road trials, or vehicle loading beyond gross ratings.

• Inspect transfer case seal joints and cooler lines each shift
• Drain and refill with recommended transmission fluid every 30,000 miles
• Inspect transmission support crossmember mounts every 12 months

Commercial Fleet Warranty Delivery Manifest

Your drivetrain purchase carries a 3-Year / 100,000-Mile commercial fleet warranty for complete operational confidence. The heavy crate encloses one remanufactured five-speed automatic transaxle, balanced torque converter, transfer case seal kit, and a dyno-tested build certificate.
