Remanufactured JF414E Automatic Transmission Complete Assembly With Torque Converter 31020‑3MX0D For Nissan Versa March Almera 1.6L HR16DE 2012‑2019 4‑Speed FWD Gearbox Direct Replacement

1.Product Overview

This remanufactured JF414E four‑speed front‑wheel‑drive automatic transmission complete assembly comes with original matched torque converter. Every core component is fully disassembled, cleaned, inspected, worn parts replaced with brand‑new spares, reassembled and dyno‑tested. It is designed as a direct drop‑in replacement for failed original gearbox for Nissan small‑displacement family sedans. Suitable for repair shop vehicle overhaul, reduces repair cycle for passenger cars.

2.Fitment & Parameter Table

3.Inspection & Testing Standard

After complete reassembly, each JF414E transmission runs on dedicated transmission dyno bench. We test shifting pressure, up‑shift & down‑shift response, lock‑up function, leakage inspection and noise check under simulated road load. All hydraulic circuits are flushed. Every unit must pass the full dyno test report before packing; failed units will go back for disassembly and rework, no unqualified products are released out of workshop.

4.Core Competitive Advantages

All friction discs, sealing gaskets, bearings and solenoids that are prone to wear have been renewed during remanufacturing process. The valve body is cleaned and calibrated. The torque converter is inspected and re‑balanced. We keep strict traceability records for every remanufacturing procedure. Direct drop‑in installation without extra modification, greatly cuts your repair time for small Nissan family vehicles.

5.Professional Installation Guidance

Before installation, confirm VIN number to verify exact gearbox part number match. Fully flush vehicle cooling radiator and transmission oil pipeline, old residual debris inside oil cooler must be cleaned completely. Fill with specified Nissan automatic transmission fluid after installation. After first road test, check for oil leakage. Complete adaptation and relearn procedure for transmission control unit, do not perform heavy‑load driving immediately after initial startup.

6.Packaging & Transportation

Each remanufactured gearbox is wrapped by thick anti‑shock foam. Then packed into sturdy export plywood crate with IPPC fumigation mark. We fix the transmission inside wooden crate with steel fasteners to avoid shifting and collision during sea or land freight. Drain partial transmission oil for international shipping to comply with dangerous‑goods transport regulations.

7.Factory Strength Introduction

Our remanufacturing workshop has long‑term experience for Japanese automatic transmission rebuilding. We own multiple transmission dyno test benches and professional dis‑assembly assembly stations. We maintain large stock for popular Nissan gearbox assemblies, support fast shipment for small‑batch orders from local repair shops, and provide technical consultation support for installation issues.

8.FAQ

Q1: Will you perform magnetic‑particle crack inspection on the used transmission housing for remanufactured JF414E?

A1: Yes, magnetic‑particle crack inspection is a mandatory procedure for every reused housing of the remanufactured JF414E automatic transmission. Before starting reassembly, our quality team carefully checks critical stress‑bearing areas including mounting bosses, bolt holes and internal oil‑way walls. If tiny cracks are discovered, the housing will be scrapped directly instead of being repaired by welding. We do not take risks with cracked casings, because hidden cracks will gradually expand after road loading and eventually cause sudden transmission failure. This strict inspection standard helps our B‑end customers reduce after‑sales complaint risks in overseas repair markets.

Q2: What is your judgment rule for re‑using planetary gears on JF414E during remanufacturing?

A2: For planetary gear sets of the JF414E transmission, we adopt strict measuring standards rather than simple visual inspection. Technicians measure tooth surface wear, gear backlash and pin hole clearance with professional micrometers. When backlash exceeds our defined tolerance value, the whole planetary assembly will be replaced. Even if there are no obvious broken teeth, minor pitting on the tooth surface will disqualify these components for reuse. We aim to eliminate early planetary‑related noise and knocking faults after vehicle installation, which brings stable quality support for your wholesale business.

Q3: When dyno testing JF414E, will you simulate high‑temperature working conditions for hot climate markets such as Latin America?

A3: Absolutely. Considering that many of our wholesale customers sell remanufactured JF414E units to Latin‑American and other tropical regions with high ambient temperatures, our dyno test will raise the operating oil temperature to 95‑110 ℃ for a period of simulated loading test. Under this high‑temperature state, our operators repeatedly check shifting pressure stability, lock‑up response and oil‑seal leakage performance. If pressure fluctuates significantly at high temperature, this transmission will be sent back for disassembly and rework. This targeted high‑temperature test helps to adapt the gearbox for hot‑zone road operation.
