U151F 2008-2013 Toyota Highlander 3.5L AWD/4WD – Remanufactured Automatic Trans

Description

Meet strict commercial fleet maintenance benchmarks with 198 lbs of dyno-certified drivetrain engineering that directs 270 horsepower through 5 computer-timed forward gear steps in the Toyota U151F Remanufactured Transmission tailored for 2008 to 2013 Highlander 3.5-liter all wheel drive utility crossovers.

Die-cast A380 aluminum casing architecture sheds heat rapidly while maintaining gear shaft centerlines under high engine loads. Upgraded valve bodies incorporate wear-resistant bore sleeves and calibrated pressure regulator valves. Transaxle specifications include an integrated transfer drive interface, 3/8-inch quick-connect cooler ports, 9.8-quart fluid capacity for genuine fluid, and an overall dry unit weight of 198 lbs.

Key Features of Toyota U151F

Commercial transport fleets buy Toyota U151F remanufactured transmission systems to lower operating costs and ensure uninterrupted service across regional highway routes. Strict component balancing eliminates driveline vibration across all vehicle speeds.

• Re-sleeved valve body passages restore hydraulic pressure integrity to prevent shift flare
• Carbon-metallic clutch packs resist thermal degradation during prolonged stop-and-go driving
• Furnace-brazed torque converter packages provide dependable lockup across highway speeds
• Computer-calibrated solenoids regulate clutch fill rates to deliver smooth gear engagement
• Toyota U151F transmissions pass complete rotational dyno load cell testing before packing
• Hardened steel planetary gears run cool and suppress gear whine inside vehicle cabins
• Dual-lip viton transfer seals prevent fluid leaks during tight municipal turnarounds

Five Speed Fluid Pressure Ratios

Engineered for high-mileage passenger transit fleets, this five-speed automatic transaxle manages 248 lb-ft continuous input torque at 4,700 RPM under 170 to 225 PSI line pressure. Sump temperature runs between 160°F and 182°F under continuous driving cycles. Forward mechanical ratios provide 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 cooling system.

Transfer Drive Spline Coupling Standard

Power exits through internal transfer drive splines machined to couple straight with factory all wheel drive transfer units. Output journal centerline runout measures under 0.0017 inches across 360 degrees. Precision-machined seal seats prevent gear oil migration onto suspension components.

Planetary Gear Carrier Inspection Procedures

Perform transmission control module electronic adaptations after installation to calibrate solenoid pressure curves. This automatic transaxle is not engineered for competitive motorsports, turbocharged engine builds, or commercial towing trailers exceeding vehicle ratings.

• Check transmission fluid level via the dipstick tube each shift
• Drain and refill with recommended transmission fluid every 30,000 miles
• Inspect transmission selector linkage bushings every 12 months

Fleet Crate Package Warranty Inclusion

Your investment includes a 3-Year / 100,000-Mile commercial fleet warranty that ensures product reliability. The crate contains one remanufactured five-speed automatic transaxle, balanced torque converter, transfer case seal kit, and a certified runout inspection document.
