Frequently Asked Questions

The JF015E (also known as RE0F11A) is a continuously variable transmission (CVT) manufactured by JATCO and used in various Nissan models including the Qashqai, Juke, Note, Micra, and Pulsar. It's a compact, fuel-efficient transmission that uses a belt and pulley system instead of traditional gears. While efficient, these transmissions require specialist knowledge for proper diagnosis and repair.

Common signs include: juddering or shaking during acceleration, whining or humming noises, loss of acceleration power, gear slipping, burning smell, transmission warning light on dashboard, delayed engagement when shifting from Park to Drive, and rough or jerky acceleration. If you experience any of these symptoms, it's important to get a professional diagnosis quickly to prevent further damage.

Our comprehensive CVT diagnostic service starts from £150 and includes fault code reading, real-time sensor data analysis, transmission pressure testing, and a detailed diagnostic report with repair recommendations and cost estimates. This is significantly less expensive than dealership diagnostics and provides more in-depth specialist analysis.

Yes, we specialize in TCM (Transmission Control Module) programming including cloning, EEPROM repair, wiped TCM recovery, and stepper motor calibration. We use professional equipment including Autel Ultra, Consult III+, and BitBox to ensure accurate programming. We can program both new and used TCMs to your vehicle's specifications.

Absolutely. All our CVT parts are genuine OEM quality components imported directly from Japan. Every part comes with a QR code for traceability and is professionally packaged with custom foam inserts to ensure safe delivery. We do not sell aftermarket or inferior quality parts.

Some parts like sensors and solenoids can be installed by skilled DIY enthusiasts with proper tools. However, components like pulley kits, valve bodies, and TCMs require specialist knowledge and equipment. We provide technical guidance and installation support with every purchase. For complex installations, we recommend working with a qualified mechanic or bringing your vehicle to us.

Yes, all our parts come with a manufacturer's warranty. Refurbished gearboxes include a 12-month warranty. Programming services are guaranteed, and we offer free re-programming if any issues arise from our work. Please see our full warranty terms or contact us for specific warranty details on individual products.

We specialize in Nissan vehicles equipped with the JF015E (RE0F11A) CVT transmission, including: Qashqai (2007-2020), Juke (2010-2019), Note (2012-2020), Micra (2010-2017), and Pulsar (2014-2018). We also support some Renault models that use the same transmission. Contact us if you're unsure whether your vehicle is compatible.

This requires a professional diagnostic assessment. Many CVT issues can be resolved with component replacements (solenoids, sensors, valve body work) or TCM programming without needing a full gearbox replacement. We'll always provide honest recommendations and explore repair options before suggesting replacement. Our comprehensive diagnostic service will identify the exact issue and the most cost-effective solution.
