Remanufactured JF017E CVT Complete Automatic Transmission Assembly OE 31020

1.Product Overview

This remanufactured JF017E complete CVT transmission is a full drop‑in replacement assembly for Nissan 2.5L front‑wheel‑drive passenger vehicles. Every used core is fully disassembled, thoroughly cleaned, inspected and rebuilt in‑house. All fatigued, worn‑out components are discarded and replaced with brand‑new matching‑grade spare parts including pressure belts, pulleys, full sealing kits, friction components, bearings and thrust washers. Main OE reference part number: 31020‑3VX0B. Every finished unit passes strict static leak test and dynamic CVT bench simulation test before shipment. Goods are delivered dry without pre‑filled CVT fluid. This full complete assembly is oriented for bulk B‑end wholesale customers, overseas importers and large repair chain stores, ready for mass container orders and sample trial purchases.

3.Inspection & Testing Standard

Each JF017E core receives strict incoming inspection. Housings with cracks, severe oil‑way corrosion or mounting‑surface deformation get directly scrapped. After full disassembly, pulleys, steel belt, pressure cylinder and internal planetary parts are measured strictly according to OEM tolerance specifications. All rubber gaskets, oil seals and bearing components are replaced brand‑new. After reassembly, static pressure holding leak test runs for 180 seconds to detect internal and external oil leakage risk. Dynamic bench test simulates real‑vehicle CVT working conditions, inspecting belt pressure ratio, shifting smoothness, pressure stability and abnormal noise. Units with pressure fluctuation, jitter or strange noise will go for full rework instead of shipment. Residual test fluid inside oil passages will be fully cleaned before packaging. Simplified test summary documents can be provided for B‑end buyers upon request.

4.Core Competitive Advantages

1. Critical vulnerable CVT parts including steel push belt and primary‑secondary pulleys are strictly screened; defective components are scrapped instead of being reused to lower early failure risk.
2. Complete dual‑mode bench testing procedure guarantees stable CVT performance, effectively reducing local after‑sales trouble for your repair business.
3. Free VIN verification service provided by our technical department, to confirm exact JF017E matching status and avoid wrong‑part delivery caused by similar‑appearing CVT housings.
4. Flexible wholesale terms: support sample trial order and large‑volume container order, neutral no‑logo export packaging available without extra service charge.
5. Optimized for known original JF017E factory defects during rebuilding process, solving common problems such as belt slip and pressure error for long‑term reliable operation.

5.Professional Installation Guidance

Installation must be completed by experienced CVT professional repair technicians. Before installation, double‑check OE part number and vehicle VIN information to prevent mismatching. Inspect torque converter condition before mounting onto engine. After mechanical installation finishes, fill vehicle‑specified CVT fluid and adjust fluid level accurately. Mandatory CVT adaptive reset and learning procedure must be finished via professional diagnostic scanner, otherwise symptoms like jitter, slipping and poor acceleration will appear. We provide English PDF guidance documents and short operation tutorial videos for your overseas repair technicians. Road test is required after installation, re‑check fluid level and all sealing positions for potential oil leakage points.

6.Packaging & Transportation

Each finished JF017E unit is secured inside IPPC heat‑treated export wooden crate, complying with international phytosanitary requirements for sea freight. Shock‑absorbing filler inside protects casting housing against collision damage on long ocean journeys. Anti‑rust agent coats all internal metal components, together with desiccant bags placed inside transmission housing to resist high‑humidity maritime environment. Custom shipping marks, customer LOGO and VIN related remarks can be printed on wooden boxes free of charge. You can choose FOB shipping with our nominated forwarder, or assign your own freight forwarder for factory pickup. The transmission is shipped dry with no CVT fluid inside. Additional customs‑related document service can be arranged according to your destination country requirements.

We maintain regular spot inventory for mainstream CVT models including JF017E, JF015E, JF011E and other popular units. Our technical team accumulates rich practical experience solving typical CVT common faults. We serve auto‑parts importers, wholesale distributors and repair‑chain clients across many overseas regions. Advance appointment supports customer factory tour to observe full production workflow. Strict quality control runs through core receiving, component replacement, assembly and final testing to stabilize product quality for B‑end wholesale cooperation.

8.FAQ

Q: Can we specify production batches and only get the latest‑produced 025CHA units for bulk orders? Are there any MOQ limits for this request?
A: Yes, we support customers to specify production batches for bulk purchases to receive newly‑manufactured 025CHA transmissions. There is a minimum‑order‑quantity threshold for this service, since we need to reserve production slots and separate finished‑goods storage space to avoid mixing older stock with fresh batches. For small sample orders, full batch selection may not always be available due to warehouse stock rotation rules. Our sales team will check real‑time factory production schedules and confirm feasible batch numbers for you before order confirmation. We will mark batch information clearly on packing lists so you can verify every shipment, which helps you avoid potential aging‑related risks from long‑term stored inventory for your local aftermarket business.

Q: What documents will you provide to prove that delivered units are brand‑new instead of rebuilt or used transmissions?
A: We can supply multiple supporting documents to verify that your 025CHA transmissions are brand‑new goods. Each shipment comes with factory original serial numbers marked on commercial invoices and packing lists, corresponding to original production records. Upon request, we can offer copies of factory outgoing inspection reports covering leakage test, sensor check and shift‑performance testing. We do not mix rebuilt, returned or second‑hand assemblies into new‑product orders. If necessary, our team can also share reference photos of original factory labels and marks for your reference. All these materials help you convince your local B‑end buyers and reduce commercial disputes in overseas aftermarket sales.

Q: Will hardware differences exist among OE numbers after original manufacturer hardware iteration? Can old and updated assemblies swap directly for installation?
A: After original‑equipment manufacturer hardware iterations, assemblies sharing one identical OE part number may contain subtle internal hardware upgrades. In some cases, updated units can fit old‑model vehicles directly, while occasional mismatches on valve‑body components or sensor parameters will cause abnormal shifting or dashboard fault codes. We cannot guarantee 100 % direct interchangeability without cross‑checking vehicle VIN information. Our technical team will compare your vehicle configuration against factory upgrade archives before shipment. We will remind you whether firmware flashing or auxiliary part replacement is required, protecting you from costly return issues after overseas installation.
