Dacia Sandero Gearbox Repair Specialists in the South East
The strongest UK Sandero automatic repair target is the third-generation TCe 90 CVT sold from 2021. Dacia offered the 1.0-litre turbo engine with either manual or CVT automatic transmission, creating a sizeable used-car market for genuine CVT diagnosis.
If your Sandero revs high without matching acceleration, judders under light throttle, hesitates before Drive or Reverse, whines with road speed or displays a transmission warning, we test CVT pressure, ratio control, speed data and internal torque transfer.

Dacia Sandero Versions and Automatic Gearboxes
Third-generation UK Sandero introduced a TCe 90 CVT automatic option from 2021. Current MY26 cars use manual powertrains, making model year particularly important when people search simply for “Dacia Sandero automatic”.
| Sandero version | Typical transmission | Key diagnostic areas | What owners often search |
|---|---|---|---|
| 2021–2024 TCe 90 CVT | Continuously variable transmission | Pressure, valve body, ratio control, speed sensors and variator | Sandero CVT problems, rev flare, judder |
| TCe 90 manual | 6-speed manual | Not part of automatic repair | Sandero manual vs automatic gearbox |
| SCe / Bi-Fuel manual variants | Manual | Separate clutch/manual repair path | Dacia Sandero gearbox problem manual |
| Current MY26 Sandero | Manual powertrains | No current UK CVT option | new Sandero automatic gearbox UK |
Check the specification: Dacia transmission and hybrid systems change by model year and powertrain. Registration/VIN identification should come before parts are ordered.

Dacia Sandero Gearbox and Drivetrain Types Explained
Pressure / Valve Body
Correct hydraulic pressure is essential for ratio control and torque transfer.
Pulley / Belt System
Excess slip or wear in the variator can cause rev flare, poor acceleration or noise.
Manual-Only MY26
The latest UK Sandero should not be confused with the earlier TCe 90 CVT when searching for automatic faults.
Common Problems
Common Dacia Sandero Gearbox Issues
Search intent includes “Dacia Sandero CVT problems”, “Sandero revs high but not accelerating”, “automatic judder”, “delayed Drive”, “CVT whining” and “Sandero automatic gearbox repair cost”.
RPM Flare / Slip
Some rev rise is normal for a CVT, but excessive engine speed without matching road speed can indicate pressure or variator slip.
Low-Speed Judder
Pressure-control, take-up or driveline faults can create vibration during gentle acceleration.
Delayed Drive / Reverse
Hydraulic pressure build-up or internal engagement can create a pause before movement.
Whining Noise
CVT bearing or variator wear can produce a road-speed-related whine, although wheel bearings should also be excluded.
Transmission Warning
Ratio, pressure, sensor or temperature faults can trigger restricted operation.
Overheating / Protection
Repeated slip or low pressure can increase heat and force the CVT into a protective mode.

Describe the Symptom
What Does a Dacia Sandero Gearbox Fault Sound or Feel Like?
Tell us whether the Sandero symptom happens from cold, after traffic, under stronger acceleration, at steady speed or immediately after selecting Drive.
| What you notice | How owners often describe it | Possible areas to investigate |
|---|---|---|
| High revs / weak pull | “The revs rise but the car does not accelerate properly.” | CVT pressure, ratio control, variator slip |
| Judder | “It shakes as I move away.” | Pressure/take-up control, internal wear, mounts |
| Delay into Drive | “D takes a moment to engage.” | Hydraulic pressure, valve body, engagement |
| Whine | “The gearbox makes a rising humming noise.” | CVT bearings, variator, wheel bearing |
| Warning / limited drive | “A transmission warning appears.” | Pressure, ratio, sensor or temperature fault |
Diagnostic Trouble Codes
Dacia Sandero Gearbox and Drivetrain Fault Codes
Sandero CVT fault codes should be compared with commanded ratio, actual ratio, input/output speed, pressure and temperature data rather than treated as proof that the complete unit has failed.
| Fault / code family | Broad area | What should be checked |
|---|---|---|
| Pressure / solenoid faults | CVT hydraulics | Line pressure, control solenoids and leakage |
| Ratio faults | Variator control | Commanded ratio, actual ratio and slip |
| Speed-sensor faults | CVT monitoring | Input/output signals and ratio plausibility |
| Temperature faults | CVT protection | Fluid condition, heat history and repeated slip |
| General transmission faults | Control system | Underlying Dacia/Renault-specific DTCs and freeze-frame data |
On the Sandero, stored codes should be interpreted with the exact transmission, freeze-frame information and relevant live gearbox/hybrid values before complete-unit replacement is considered.
Repair Costs
How Much Does a Dacia Sandero Gearbox Repair Cost?
Sandero CVT repair cost depends on whether the failure is electrical/control, hydraulic or internal to the variator.
| Dacia Sandero CVT work | Typical guide range | What can change the price? |
|---|---|---|
| Diagnostic scan and CVT road test | From £30 | Fault reproduction and transmission condition |
| Sensor / solenoid repair | Approx. £400 - £1,000+ | Electrical or hydraulic component |
| Valve-body / pressure repair | Approx. £700 - £1,600+ | Hydraulic wear and leakage |
| Targeted internal CVT repair | Approx. £1k - £2.2k+ | Bearing / variator involvement |
| Full CVT reconditioning | Approx. £1.8k - £3.8k+ | Internal pulley/belt and hard-part damage |
Important: These are broad guide ranges rather than fixed advertised prices. The final quotation follows diagnosis of the exact transmission and drivetrain.

How We Diagnose a Dacia Sandero Gearbox Fault
Identify the transmission
Confirm the Sandero is a third-generation TCe 90 CVT rather than a manual derivative.
Read Dacia-specific data
Read pressure, requested/actual ratio, input/output speed and temperature data with Dacia/Renault-compatible diagnostics.
Reproduce the symptom
Reproduce the rev flare, judder, delay or whine during the condition where it appears.
Quote the right repair
Quote the control, valve-body, variator or internal CVT repair demonstrated by testing.

Common Search Questions
Dacia Sandero Gearbox Problems: Straight Answers
Which Dacia Sandero models use a CVT automatic gearbox?
Third-generation UK Sandero TCe 90 models were offered with a CVT automatic from 2021, alongside manual versions.
Does the current MY26 Dacia Sandero have an automatic gearbox?
No. The current UK MY26 Sandero range is manual-only; the CVT repair market is mainly earlier third-generation TCe 90 cars.
Why does my Dacia Sandero CVT rev high without accelerating properly?
Excessive flare can indicate hydraulic pressure loss, ratio-control problems or internal CVT variator slip.
Why is my Sandero CVT slow to engage Drive?
Hydraulic pressure build-up, valve-body control or internal engagement problems can cause delayed Drive or Reverse.
Can a Dacia Sandero CVT gearbox be repaired?
Yes. Sensor, solenoid, valve-body, bearing and internal CVT repairs may be possible depending on the confirmed fault.
Is it safe to drive a Sandero with a CVT warning?
If the car is slipping, overheating, losing drive or repeatedly entering restricted operation, arrange diagnosis before continuing normal use.
