A750F 2005-2009 Toyota 4Runner 4.0L AWD/4WD – Remanufactured 5-Speed Automatic Trans

Description

Die-cast A380 aluminum casing structures and high-tensile ductile iron carriers absorb four-wheel-drive torsional shock while managing 282 lb-ft torque during relentless regional commercial utility transit. Fleet owners select the Toyota 4Runner 4WD Remanufactured Transmission for 2005 to 2009 4.0L models to eliminate shift flare and maintain schedule punctuality.

A rigid die-cast aluminum casing withstands heavy torsional loads behind 4.0L 24-valve 1GR-FE V6 engines. Rebuilt valve bodies feature reamed hydraulic bores fitted with hard-anodized Sonnax sleeves that eliminate internal fluid cross-bleed. High-energy carbon composite clutch discs dissipate thermal loads across steel reaction plates. Specifications include an empty dry weight of 192 pounds without torque converter, an 11.2-quart Toyota Genuine WS fluid capacity, and standard 3/8-inch threaded cooler line ports.

Key Features of 4Runner 4WD

Commercial fleet operators buy 4Runner 4WD remanufactured transmission units to restore work truck productivity across grueling municipal transit routes. Every remanufactured 5-speed transmission incorporates upgraded internal wear components and solenoid blocks to surpass original factory durability standards under severe transit duty.

• 175 PSI peak line pressure clamps clutch packs tight to eliminate flare.
• 5 forward gear ratios optimize acceleration and highway cruising economy.
• Hard-anodized valve bore sleeves halt hydraulic fluid bypass inside the body.
• Radial groove carbon friction plates resist glazing under stop-and-go driving conditions.
• Furnace-brazed torque converters eliminate internal fin vibration at highway cruising speeds.
• High-output fluid pumps preserve hydraulic pressure across high operating temperatures.
• A 4Runner 4WD transaxle unit utilizes pulse-width modulated linear shift solenoids.
• Precision planetary carrier gear sets maintain tight lash tolerances under continuous load.

Operating Pressures V6 Reduction Matrix

Main line fluid circuits maintain between 130 and 175 PSI pump pressure to lock clutch packs without slip under load. Operating sump temperatures stay within a stable 155°F to 185°F range to safeguard transmission fluid integrity. The gear train withstands 282 lb-ft continuous input torque at 3,800 RPM under High-Mileage Transit service conditions. Auxiliary cooler channels dissipate 25 kW of heat through internal radiator heat exchangers. Gear ratios measure 3.52:1 in first, 2.04:1 in second, 1.40:1 in third, 1.00:1 in fourth, and 0.72:1 in overdrive.

Transfer Case Shaft Connection

A precision-ground 23-spline rear output shaft mates straight with factory Toyota 4WD transfer cases. The internal park pawl mechanism holds up to 1,650 lb-ft holding torque to hold loaded midsize trucks on steep inclines. Technicians must check driveshaft universal joint play and verify transfer adapter runout within 0.002 inch.

Utility Four Wheel Maintenance Schedule

Pulse-width modulated shift solenoids communicate with the vehicle powertrain control module to coordinate precise gear shift sequences. Note that this 5-speed transmission is not engineered for track drag strip racing, extreme rock crawling buggies, or commercial cargo towing exceeding vehicle gross weight ratings.

• Check transmission fluid level and inspect fluid color using overflow check plugs each shift.
• Drain fluid pan and replace the internal pickup filter every 30,000 miles.
• Flush radiator cooler lines and verify pump circuit pressure every 12 months.

Utility 4WD Delivery Container

Every transaxle includes a 3-Year / 100,000-Mile commercial fleet warranty for complete operational peace of mind. The heavy wooden transit container contains the complete remanufactured transmission, a balanced lockup torque converter, brand-new drive axle seals, an installation guide, and an ATSG dyno verification test sheet with recorded pressure graphs.
