Remanufactured JF011E RE0F10A 4WD CVT Automatic Transmission Assembly 31020‑1XF0B for Nissan X‑Trail T31 2.5L 4‑Wheel‑Drive 2007‑2013 Gearbox Replacement For Vehicle Repair

1.Product Overview

This is remanufactured JF011E (also known as RE0F10A) 4‑wheel‑drive CVT automatic transmission assembly for Nissan X‑Trail T31 2.5L. This transmission is a common failure unit for T31 chassis; typical original faults include belt wear, pulley scoring, shudder during acceleration, slipping, whining noise, and diagnostic trouble codes P0740, P0846. During our remanufacturing process, worn critical components are replaced, including steel push belt, primary & secondary pulleys, solenoid valve set, oil seals and bearings. The complete transmission assembly comes with torque converter, ready for direct replacement. Main OE part number: 31020‑1XF0B.

2.Fitment & Parameter Table

3.Inspection & Testing Standard

After full disassembly, every housing is cleaned in high‑pressure hot washing tank. All internal hard parts are measured by precision gauges to judge reuse eligibility. Damaged pulleys, worn push belt, failed bearings and ageing seal kits are replaced with new spare parts. After reassembly, each remanufactured JF011E unit runs on transmission dynamometer bench test. We test forward‑reverse shifting, hydraulic pressure, torque load simulation, check for internal leakage, abnormal whining noise and slipping under simulated driving load. Units with unqualified dyno data will be completely reworked before release. We also carry out final visual inspection for housing surface and threaded mounting holes before packing for export.

4.Core Competitive Advantages

1. Key vulnerable CVT components including steel drive belt and pulley assemblies are renewed, effectively solving the well‑known JF011E belt‑failure risk.
2. Complete dynamometer load testing after remanufacturing, not only static pressure test, reduces on‑road failure risk after installation for repair workshops.
3. Supplied as a complete assembly with torque converter included, drop‑in replacement, no need to source extra separate components.
4. Strict cleaning for transmission housing and oil galleries to eliminate residual metal debris left from previous failures.

5.Professional Installation Guidance

Before installing this remanufactured JF011E 4WD CVT gearbox, you must fully replace the transmission oil cooler assembly instead of simple flushing. The old cooler often contains tiny metal particles generated by the previous broken CVT belt; residual debris will quickly destroy the newly rebuilt transmission. Install new genuine‑spec CVT fluid (NS‑3 Nissan CVT fluid). After mechanical installation is finished, perform CVT adaptive learning and reset TCM. Complete extended road test covering low‑speed, medium‑speed and highway cruising, confirm there is no whining noise, judder or slipping during acceleration.

6.Packaging & Transportation

First wrap the whole transmission with thick anti‑rust VCI film and shock‑absorbing foam padding. Then fix the gearbox inside a solid IPPC heat‑treated export wooden crate. Internal wooden support blocks lock the heavy transmission firmly to prevent shifting and collision during sea or air transport. Outer wooden case is clearly printed with part number, gross weight, dimension and shipping mark information. The fumigated wooden packing meets import inspection requirements for most overseas countries.

7.Factory Strength Introduction

Our workshop specializes in remanufacturing Nissan and Jatco CVT transmission assemblies, including JF011E, JF015E and JF017E series. We own dedicated transmission dis‑assembly workstations and professional transmission dynamometer test benches. We keep regular stock of remanufactured CVT units, supplying auto repair shops and spare‑parts merchants globally. Each production batch follows unified remanufacturing procedure and QC workflow, we can provide inspection record documents for B‑end wholesale clients.

8.FAQ

Q1: When remanufacturing JF011E transmission, will you conduct flatness inspection on the TCU‑valve body mounting surface of the housing?

A: Yes, we perform formal flatness inspection for the TCU‑valve body mounting surface on every transmission housing during our remanufacturing workflow. After high‑pressure hot washing, our technicians use precision measuring tools to check this critical sealing plane. If the surface has slight distortion, scratch or uneven deformation, the housing will be rejected and cannot go on for reassembly. Uneven mounting surface is a hidden trouble which will gradually cause hydraulic oil seepage after long‑term running. Strict inspection on this plane helps us reduce later oil‑leak related warranty claims for our wholesale partners and their downstream repair workshops.

Q2: Can you supply water‑mark‑free high‑resolution product photos and short‑run transmission dyno test video resources for our online store and social‑media marketing?

A: We are glad to provide you with a set of watermark‑free high‑resolution product photos as well as short dyno‑testing clip resources after your formal order is confirmed. These marketing assets can be used for your independent‑site product listings, Facebook posts and local wholesale promotion. However, these video and picture materials are only permitted for your commercial sales promotion of our remanufactured transmissions, and you cannot resell or redistribute these media files to other competing spare‑parts dealers. We will send these digital files via online cloud link once your deposit is received to support your overseas B2B marketing work.
