The automatic transmission assembly with reference numbers 35000-35B40 and 35000-35C70 is designed for the Toyota/Aisin A750F 5-speed automatic transmission. Specifically engineered for longitudinal 4WD layouts and heavy-duty applications, this robust unit is built to handle the high torque of the 4.0L V6 (1GR-FE) engine in the Toyota Land Cruiser Prado, FJ Cruiser, 4Runner, and related off-road platforms.

Quick Specifications:

Part Numbers: 35000-35B40 / 35000-35C70 (Toyota OEM format)
Transmission Model: A750F (5-Speed Automatic 4WD)
Engine Compatibility: 4.0L V6 (1GR-FE) and similar heavy-duty powertrains
Configuration: Longitudinal Four-Wheel Drive (4WD)
Max Input Torque: ~400-450 Nm (Heavy-Duty Variant)
Fluid Type: Toyota ATF WS (World Standard)
Fluid Capacity: ~9.0 - 11.0 Liters (dry fill, varies by cooler size and transfer case)

Applications:

Toyota Land Cruiser Prado 120 / 150 (2002-2015, 4.0L 1GR-FE V6 4WD)
Toyota FJ Cruiser (2007-2014, 4.0L 1GR-FE V6 4WD)
Toyota 4Runner (2003-2009, 4.0L V6 4WD)
Toyota Tacoma (2005-2015, 4.0L V6 4WD)
Toyota Hilux / Fortuner / SW4 (Select 4.0L V6 4WD global markets)
Lexus GX 470 (Select variants sharing the A750F 4WD platform)

Complete Assembly Includes:

✅ Heavy-duty 4WD transmission case with reinforced bellhousing
✅ High-capacity torque converter with lock-up clutch
✅ Valve body with precision shift solenoids and pressure regulators
✅ Planetary gear sets, clutch packs, and brake bands
✅ Oil pump, filter, speed sensors, and sealing gaskets
✅ Transfer case adapter housing and 4WD output shaft interface

Note: Transmission mounts, shift linkages, transfer case assembly, front/rear driveshafts, and external cooler lines must be transferred from the original unit or purchased separately.

Key Features:

✅ Heavy-Duty 4WD Architecture: Specifically reinforced to withstand the extreme torque, thermal loads, and mechanical stress of off-road driving, rock crawling, and heavy towing.
✅ Longitudinal Layout: Optimized for traditional body-on-frame SUVs and pickup trucks, providing excellent weight distribution, ground clearance, and durability.
✅ Tow/Haul Mode & ECT: Shift logic adapts to heavy loads and driver input (via Electronically Controlled Transmission), holding lower gears longer to prevent excessive shifting and overheating.
✅ Multi-Gear Lock-Up: The torque converter lock-up clutch engages in multiple forward gears to reduce slippage, improve fuel economy, and lower transmission temperatures.
✅ Proven Reliability: The A750F series is widely regarded as one of the most durable, serviceable, and reliable 4WD automatic transmissions ever built by Toyota/Aisin.

Technical Notes:

Critical Installation Requirements:

Fluid Specification: Must use Toyota ATF WS (World Standard) exclusively. Using older ATF T-IV, Dexron, or incorrect fluids will cause severe shift issues, overheating, and internal clutch damage due to incompatible friction modifiers and viscosity.
Fluid Level Check: Must be performed with the transmission at operating temperature (typically 70°C–80°C) and the engine idling, using the overflow check plug on the transmission pan.
Transfer Case Mating: When mating the transfer case to the A750F, ensure the input gear splines are properly aligned and lubricated with assembly grease to prevent binding or stripping.
ECU/TCM Reset: After installation, the ECU memory reset and shift adaptation learning must be performed using Toyota Techstream or equivalent diagnostic tools to ensure smooth gear transitions and proper line pressure.
Cooler Flushing: The transmission cooler (often integrated into the radiator) and external lines must be thoroughly flushed to remove metallic debris and clutch material from the failed unit.

Common Issues & Maintenance:

Overheating in Extreme Conditions: While incredibly robust, the A750F can run hot during slow-speed rock crawling, deep sand driving, or heavy towing. Installing an auxiliary transmission cooler with a thermostat is highly recommended for extreme off-road use.
Valve Body Sleeve Wear: High-mileage units may experience wear in the valve body booster sleeves, leading to harsh shifts, delayed engagement, or burnt clutches. Regular fluid changes prevent abrasive debris from accelerating this wear.
Fluid Service Intervals: Despite "lifetime" fluid claims in some manuals, a drain and fill every 60,000–80,000 km (or more frequently if towing/off-roading) is strongly recommended to maintain shift quality and extend the lifespan of the transmission.
