A judder accelerating in your X-Trail, a whine on the highway, or “Check Engine + CVT” with limp mode — Nissan CVT faults need specialist care.
Nissan Jatco belt/chain CVTs rely on precise pulley pressure and step-motor ratio control. Finding a qualified Nissan automatic gearbox specialist near you prevents misdiagnosis and unnecessary full-unit replacement.

Our Nissan Gearbox Service Protocol
1. Consult Live Data & CVT Analysis
Beyond generic codes: target vs actual ratio, primary/secondary pulley pressure, step-motor position, belt slip, lock-up duty, and CVT fluid aging via Nissan Consult.
2. Step-Motor & Valve Body Repair
- Step-motor testing and replacement (classic JF011E fault).
- Ratio-control valve, lock-up solenoid, and valve body overhaul.
3. Belt / Clutch Rebuilds
OEM Jatco belt/chain, pulleys, pump, seals, and torque-converter testing for CVTs; clutch packs for RE7R01A automatics.
4. Correct NS Fluid Service
Nissan NS-2 / NS-3 CVT fluid to specification — never mixed or generic. Pan-drop with strainer, cooler flush, temperature leveling, and fluid degradation reset.
5. Ratio Calibration & Load Road Test
Ratio learn, lock-up adaptation, and highway-load verification where judder and whine appear.
