Remanufactured K313 CVT Transmission Gearbox For Toyota Corolla Levin 1.8L 2ZR-FE 2014-2019 FWD 30400-02010 Complete Unit With Torque Converter, Bench Tested Factory Direct Supply For Auto Repai

This is our premium remanufactured K313 CVT transaxle assembly, complete with torque converter, solenoid valve body, internal pulley set, CVT chain, oil pan and built-in filter. We replace most wearable internal parts with original OEM new components during remanufacturing, to extend service life and avoid common CVT failure issues like belt slip, shudder, abnormal noise and pressure loss. Every finished unit runs on professional CVT test bench before shipment, fully following Toyota factory specification standards. It is a drop-in replacement solution for Toyota Corolla / Levin 1.8L FWD vehicles, widely supplied for repair shops, auto service centers across global aftermarket markets.

Note: Please confirm VIN and original OE number before ordering, K313 has many sub-version differences, not universal for all Corolla.

Our remanufacturing and testing workflow strictly follows Toyota OE standards. After full disassembly, all hard parts are cleaned, inspected and measured with precision gauges. Worn pulleys, CVT chain, bearings, seals, gaskets, clutch friction components are replaced by OEM new spare parts. After reassembly, each K313 unit goes through a dedicated CVT test bench for 30+ minutes dynamic testing: line pressure check, forward/reverse shifting test, torque load simulation, temperature stability test, solenoid function verification, no leakage inspection. We record test data and generate an independent test report with serial number for every gearbox. Units with abnormal pressure, shudder or leakage will be rejected directly and reworked.

1. Factory direct, not trading company: 20 years transmission remanufacturing experience, monthly output over 1000 units, export to 150+ countries.
2. High reman standard: Majority wearable internal components are OEM brand new, far more durable than ordinary rebuilt gearboxes only cleaning and reusing old parts.
3. Special CVT test bench for K313, dynamic load test instead of simple static inspection, greatly reduce on-car failure risk.
4. Professional engineer team provides after-sale technical support for repair shops, guiding coding, oil filling and adaptive learning.
5. We can also supply brand new OEM, used good condition and aftermarket replacement K313 spare parts separately for your stock matching.

Before installation: Clean the engine oil cooler thoroughly, clogged cooler is the top reason for new CVT failure after replacement. Do not reuse old contaminated CVT fluid. Use Toyota CVT Fluid TC only. After physical installation, connect Toyota diagnostic scanner to clear old DTC codes, perform reset and CVT adaptive learning procedure strictly. Road test under low load first to complete the adaptation process. Avoid heavy acceleration within first 150km after installation. If you meet abnormal codes or shudder issues, contact our engineers, we provide step-by-step remote guidance.

Each K313 transmission is packed separately in export fumigated wooden crate. We use thick shock-absorbing foam to wrap housing, valve body and torque converter, protective plastic plugs seal all oil ports to prevent dust, moisture and oil leakage during sea or air transit. Outer crate marks include part number, serial number, weight & dimension. We provide packing list, commercial invoice and inspection report together. We support sea freight, air freight and express delivery. For bulk order, mixed loading with other transmission models and spare parts is acceptable.

We are a professional remanufacturing transmission factory with 20 years of experience, focusing on automatic transmission assemblies and related spare parts. Our products are exported to more than 150 countries globally, with stable monthly production of over one thousand gearboxes. Our reman process is rigorous; most wearable components are upgraded to original new parts to extend service life. Every unit is tested by professional test bench according to OEM factory standards. We own multiple senior transmission engineers to handle technical after-sales problems, which most traders cannot support. Besides reman units, we also supply genuine new, second-hand tested and aftermarket transmissions and components.

A1: The K313, K310, K311 and K312 look quite alike externally, which often causes misordering among repair technicians. We mark each remanufactured K313 with clear casting number tags, unique serial stickers and highlight the difference on valve body structure and plug pin layout for easy identification. Before shipment, we will send you a comparison chart covering housing casting marks, connector pinouts and internal pressure plate differences. You can forward this reference material directly to your repair clients to avoid wrong installation. Our engineers are also available to help confirm model identity if your customers send photos of their original gearbox. This helps you cut fitment disputes and return losses greatly for your wholesale business.

A2: Yes, we have targeted improvements for the well-known low-speed shudder defect of the K313 CVT during our remanufacturing process. We replace the original pressure cylinder assembly with precision-inspected new parts, upgrade the thrust bearing set and use high-quality brand-new CVT belt with stable friction coefficient. Every finished unit will go through a special low-speed creep simulation test on our dedicated CVT test bench to verify shudder-free performance under alternating oil temperature and load. We will attach the test curve record for each unit. This upgraded version performs far better than regular rebuilt units and helps your downstream shops reduce repeated after-sales complaints from end vehicle owners.

A3: Absolutely, we can provide a full English guideline file including pre-installation check, cooler cleaning requirement, correct CVT fluid type, DTC clearing steps, static adaptation and on-road learning procedures for K313. This document is written for technicians without deep experience on Toyota CVT systems. It also lists forbidden operations such as heavy acceleration during adaptation and using non-Toyota TC fluid. You can share this PDF freely with all your repair clients. If any of your partners get stuck during coding or learning, our professional transmission engineers can offer remote step-by-step guidance via message or video call to support your aftersales service.
