Pressure-control wear can cause harsh shifts, delays or ratio faults.
Torque Converter
Lock-up slip can create vibration at steady throttle.
Internal Clutch Packs
Pressure loss or wear can cause flare, slip or missing ratios.
Common Problems
Common Peugeot 407 Gearbox Issues
High-intent owner searches include “407 automatic gearbox fault”, “Peugeot 407 AM6 valve body”, “407 Coupe gearbox shudder”. The symptom helps narrow the fault, but the transmission code determines the correct repair route.
Delayed Drive / Reverse
Hydraulic fill or clutch sealing can cause a pause before movement.
Harsh Shift
Valve-body or solenoid faults can make changes abrupt.
Converter Shudder
Lock-up slip can produce a cruise vibration.
RPM Flare / Slip
Internal clutch wear or pressure loss can let revs rise.
Transmission Warning
Ratio, pressure or speed faults can trigger limp mode.
Fluid / Temperature Fault
Heat or contamination can worsen hydraulic control.
Describe the Symptom
What Does a Peugeot 407 Gearbox Fault Sound or Feel Like?
Tell us when the symptom occurs and whether it changes with temperature, road speed, engine load or gear selection.
| What you notice | How owners often describe it | Possible areas to investigate |

| Delayed Drive / Reverse | “It takes a moment before the vehicle moves.” | Hydraulic fill or clutch sealing can cause a pause before movement. |
| Harsh Shift | “It changes gear too sharply.” | Valve-body or solenoid faults can make changes abrupt. |
| Converter Shudder | “It shakes or vibrates under this condition.” | Lock-up slip can produce a cruise vibration. |
| RPM Flare / Slip | “The revs rise without matching road speed.” | Internal clutch wear or pressure loss can let revs rise. |
| Transmission Warning | “A gearbox warning appears and operation may be restricted.” | Ratio, pressure or speed faults can trigger limp mode. |

Common Search Questions
Peugeot 407 Gearbox Problems: Straight Answers
What automatic gearbox does the Peugeot 407 use?
It depends on version and model year. UK automatic applications include 4-speed automatic on relevant versions, 6-speed AM6 automatic, 6-speed automatic on key derivatives. Registration/VIN and gearbox identification should come before parts are ordered.
Why does my Peugeot 407 judder or hesitate?
On the 407, judder can come from clutch/actuator control, hydraulic pressure, converter lock-up, CVT/DSG operation or the wider drivetrain depending on the transmission fitted.
Why is my Peugeot 407 slow to select Drive or Reverse?
Delayed engagement can involve hydraulic pressure, clutch filling, actuator response, selector control or internal sealing depending on the gearbox type.
Can a Peugeot 407 gearbox be repaired instead of replaced?
Yes. Many clutch, actuator, mechatronic, valve-body, torque-converter and targeted internal faults can be repaired once diagnosis confirms the failed component.
How much does a Peugeot 407 gearbox repair cost?
Cost depends on the exact transmission and fault. A diagnostic assessment should come first because a targeted control or clutch repair costs far less than a complete reconditioned gearbox.
Should I keep driving a Peugeot 407 that is slipping or showing a transmission warning?
Driving should be reduced because repeated slip and heat can increase clutch, hydraulic or internal gearbox damage.
