Remanufactured UB80E AWD All‑Wheel‑Drive Automatic Transmission OE 35010‑0E041 For Toyota Highlander Sienna 3.5L AWD 2018‑2023 Rebuilt AWD Gearbox Assembly

1.Product Overview

This remanufactured UB80E AWD all‑wheel‑drive automatic transmission assembly is specially rebuilt for Toyota AWD platform vehicles. Different from FWD version, this AWD variant comes with unique rear output transfer‑case connection structure, matching Highlander and Sienna 3.5L all‑wheel‑drive models built from 2018‑2023. Whole unit undergoes full disassembly, deep cleaning, component screening, wear‑part replacement and AWD‑specific bench simulation test. Torque converter, complete valve‑body, renewed seal kit, oil pan and AWD relevant internal transfer components are all included within this complete assembly. All fatigue‑prone friction discs, rubber seals, bearings are replaced with OEM‑equivalent brand‑new parts. This product solves common AWD gearbox faults including slipping, pressure fluctuation and abnormal noise, perfect for overseas repair shops and distributors serving large volume AWD Toyota vehicles.

3.Inspection & Testing Standard

Every AWD‑spec UB80E implements strict inspection workflow. Aluminum housing will complete fluorescent penetrant crack detection, cracked housing will be scrapped directly. All friction components, sealing gaskets, pistons, thrust bearings and AWD transfer‑related wear parts are replaced by new OEM‑equivalent spare parts. After full assembly, static 15‑minute pressure holding leak test is performed to check all sealing positions including AWD transfer section. Afterwards dynamic bench test simulates AWD working condition, running multiple shifting cycles, monitoring line pressure, lock‑up performance and transfer output stability. Units with abnormal noise, pressure deviation or shifting failure will be disassembled and reworked. Only fully qualified AWD units can go into packaging procedure. We preserve internal testing records for bulk wholesale clients.

4.Core Competitive Advantages

This is dedicated AWD UB80E variant, not modified converted from FWD housing, avoid AWD transfer‑matching failure risk. All AWD‑specific internal components get thorough inspection and wear‑part renewal, not reused old worn AWD parts. Full AWD‑condition bench testing is completed for each unit instead of only FWD mode test. We offer free VIN‑code decoding service to distinguish FWD and AWD UB80E hardware to prevent wrong ordering. OEM‑equivalent replacement consumable parts ensure long‑term service life. Neutral export packing available without extra custom cost. Support small‑batch AWD sample order and large‑volume container wholesale, mixed‑loading with other gearbox models is acceptable.

5.Professional Installation Guidance

Only well‑experienced AWD transmission technician should perform installation work. Use vehicle VIN code double‑check to confirm you really need AWD‑spec UB80E, FWD version cannot adapt to AWD powertrain. Thoroughly clean engine mating surface and AWD transfer connection position, eliminate metal debris and old gasket residues. Unit is delivered dry without pre‑filled ATF fluid, fill manufacturer‑specified ATF oil with correct volume before vehicle startup. After mechanical installation, complete transmission adaptive learning procedure, and also check AWD system relevant error codes. We provide English PDF guide and short‑video files for your local repair technicians. Skipping calibration will result in shifting trouble or AWD system malfunction.

6.Packaging & Transportation

Each AWD UB80E complete transmission is packed in heavy‑duty IPPC heat‑treated export wooden crate. Inner shock‑absorbing foam and fixed tension straps protect AWD transfer output end, aluminum housing and sensor connectors from collision damage during long‑distance sea shipment. Anti‑rust protective coating is applied on exposed metal surfaces for marine humid‑environment protection. Printing your company logo, shipping marks and VIN reference notes on wooden crate is free. Two shipping choices are available: our cooperative forwarder gives freight quote, or your designated forwarder picks‑up goods from factory warehouse. We prepare export documents complying with your destination country customs requirements.

7.Factory Strength Introduction

Our factory has over 15‑year experience on automatic transmission remanufacturing business. We own complete production lines for disassembly, multi‑stage high‑pressure cleaning, component inspection, assembly and bench testing. We maintain ready stock for multiple FWD and AWD transmission variants, support sample trial order and FCL bulk wholesale. Long‑term overseas B‑end partners get dedicated one‑on‑one foreign trade contact for technical consultation, order follow‑up and after‑sales problem handling. Overseas buyers are welcome to schedule factory visit to observe full remanufacturing workflow. Besides complete AWD/FWD assemblies, we can also supply UB80E overhaul repair kits for your local aftermarket market.

8.FAQ

Q:What will happen if we cancel partially produced UB80E items within a confirmed order, how do you define losses of pre‑purchased special spare parts?
A:After order confirmation and deposit received, if you request partial cancellation for items already under production, we will assess current production progress. For units not yet started, cancellation can be accepted without extra loss charges. For UB80E units where special customized spare parts have already been procured, those dedicated components cannot be reused for other general orders. The cost of these non‑convertible parts shall be borne accordingly. Our team will supply detailed cost breakdown list for your review. We try our best to negotiate flexible solution for stable long‑term partners. Therefore we suggest fully confirming your demand before placing formal order to prevent unexpected commercial losses for both sides.

Q:What is your handling standard for UB80E housing with minor oil‑way corrosion during remanufacturing process, will corroded housings still be assembled for finished goods?
A:During disassembly inspection, all UB80E housings go through careful visual and dimensional check for oil‑way corrosion. Slight surface stain will be removed by professional chemical cleaning and high‑pressure flushing. Once corrosion causes oil‑wall pitting, dimensional deformation or partial oil‑channel cross‑section change, this housing will be directly scrapped and will never flow into reassembly procedure. Corroded oil‑way may lead to unstable hydraulic pressure, hidden shifting faults and shorten service life. We never adopt repairing measures like simple polishing for severely corroded housing to cut cost. Strict housing screening standard helps lower your local after‑sales complaint rate and protect your business reputation in overseas repair‑parts market.

Q:For UB80E AWD variant, will you separately execute sealing and rotational‑load testing on the transfer‑output section in your factory test procedure?
A:Yes, for every remanufactured UB80E AWD unit, the transfer‑output position receives independent inspection items besides full‑unit pressure‑leakage test and dynamic bench test. We run rotational‑load simulation to check output‑shaft running smoothness, abnormal noise and sealing performance of transfer‑related sealing surfaces. Any oil‑leak trace, jitter or strange noise appearing at transfer‑output area will trigger full rework. We do not treat AWD version same as FWD unit by skipping transfer‑part verification. This set of testing aims to catch hidden defects before goods are packed. After units arrive at your destination market, local technicians can complete installation following our guidance and avoid premature failure on transfer output section under real‑vehicle AWD driving load.
