Citroen cars use different types of automatic transmissions, depending on the model:
- Aisin classic automatic transmissions (with torque converter).
- ETG/EGS – robotic mechanical gearboxes (mostly in small models).
- ZF – in certain premium and SUV models (DS4, DS7).
What gearboxes are available in Citroën cars?
- Aisin AT6/AT8 – C4, C5, C5 Aircross, DS3, DS4.
- ETG5 / ETG6 (EGS) – C3, C4 Picasso, C-Elysée (robotized).
- ZF 8HP – DS7 Crossback (luxury segment).
How is the repair going?
- Diagnostics – checks for errors in the control unit, pressure, clutch operation (for robotics).
- Disassembly and troubleshooting – clutches, solenoids, friction, valve block are checked.
- Clutch replacement (ETG/EGS) is a common problem in robotic gearboxes.
- Hydraulic block repair (Aisin/ZF) – a common problem with knocks or slipping.
- Oil change – very important for Aisin and ZF gearboxes, does not apply to ETG.
- Adjustment and final testing – electronic adaptation.
The most common problems:
- ETG/EGS: jerking, delay, clutch wear.
- Aisin: knocks, overheating, oil leaks.
- ZF: high load damage, solenoid defects.
Technical disadvantages:
- ETG/EGS: low comfort gear shifting, frequent clutch changes.
- Aisin: sensitive to oil changes, knocks on wear.
- ZF: expensive repairs, but high quality.
Approximate repair costs:
- ETG clutch replacement: €500–900
- Aisin hydraulic unit repair: €800–1400
- Oil change (Aisin/ZF): €250–400
- Full repair (Aisin/ZF): €1500–3000
