The automatic transmission assembly with reference number 30500-33860 is designed for the Aisin UA80E 8-speed automatic transmission. Part of Toyota's next-generation TNGA powertrain lineup, this advanced transverse unit features a compact Lepelletier-derived gearset and a wide 7.59:1 ratio spread, delivering exceptionally smooth shifts, rapid response, and outstanding fuel efficiency for the Toyota Camry, Avalon, RAV4, Lexus ES250/ES350, and related platforms.

Quick Specifications:

Part Number: 30500-33860 (Toyota OEM format)
Transmission Model: UA80E (8-Speed Automatic)
Also Known As: Aisin AWF8F35
Type: Transverse Front-Wheel Drive (FWD)
Engine Compatibility: 2.5L (A25A-FKS), 2.5L Hybrid, 3.5L V6 (2GR-FKS)
Max Input Torque: ~350-400 Nm (3.5L V6 variant)
Gear Ratio Spread: 7.59:1
Fluid Type: Toyota ATF WS (World Standard)
Fluid Capacity: ~6.5 - 7.5 Liters (dry fill)

Applications:

Toyota Camry (XV70, 2018-present, 2.5L & 3.5L V6 FWD variants)
Toyota Avalon (XX50, 2019-2022, 3.5L V6 variants)
Toyota RAV4 (XA50, 2019-present, 2.5L FWD variants)
Lexus ES250 / ES350 (XZ10, 2019-present, 2.5L & 3.5L variants)
Lexus NX (Select 2.5L non-hybrid variants)
Toyota Highlander / Kluger (Select 2.5L / 3.5L FWD variants)
Toyota Sienna (Select non-hybrid global market variants)

Complete Assembly Includes:

✅ Lightweight aluminum transmission case with compact 8-speed geartrain
✅ High-efficiency torque converter with wide-range Flex Lock-up clutch
✅ Valve body with precision linear solenoids and advanced pressure control
✅ Integrated Transmission Control Module (TCM) or ECU control interface
✅ Multi-plate clutch packs, brake elements, and high-volume oil pump
✅ Input/Output speed sensors, range selector, and sealing gaskets

Note: Transmission mounts, shift cables, axles, and external cooler lines may need to be transferred from the original unit.

Key Features:

✅ Wide 7.59:1 Ratio Spread: Lower 1st gear for stronger acceleration and a taller 8th gear for relaxed, low-RPM highway cruising and improved fuel economy.
✅ Compact Packaging: Achieves 8 speeds in a footprint comparable to older 6-speed units through an optimized Lepelletier-derived gearset architecture.
✅ Expanded Flex Lock-Up: The torque converter lock-up clutch engages from 2nd gear onward in most conditions, minimizing slippage and providing a direct, responsive driving feel.
✅ High-Speed Shift Response: Reduced shift times compared to the U760E predecessor, with near-instantaneous gear changes during aggressive acceleration.
✅ TNGA Integration: Designed to work seamlessly with Toyota's TNGA platform electronics, Dynamic Force engines, and Toyota Safety Sense systems.

Technical Notes:

Critical Installation Requirements:

Fluid Specification: Must use Toyota ATF WS (World Standard) exclusively. Using incorrect fluid will compromise the Flex Lock-up clutch friction characteristics and cause severe shudder or shift malfunctions.
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.
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 proper line pressure, shift timing, and lock-up clutch engagement.
Cooler Flushing: The transmission cooler (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:

Adaptive Learning Period: The UA80E relies heavily on adaptive shift logic. Rough or delayed shifts immediately after installation usually resolve after a complete TCM reset and a 50-100 km drive cycle relearning procedure.
Valve Body Sensitivity: The precision linear solenoids are sensitive to fluid contamination. Regular fluid changes prevent abrasive debris from causing sticky solenoids or harsh shifts.
Torque Converter Shudder: A vibration during light throttle or lock-up engagement can occur if ATF WS fluid degrades. A complete fluid exchange typically resolves this issue.
Fluid Service Intervals: A drain and fill every 60,000–80,000 km is strongly recommended to maintain shift quality, protect the Flex Lock-up clutch, and extend the lifespan of the UA80E.
