Honda CVT
The Mk2 Honda CVT uses continuously variable ratio control with simulated steps. Hydraulic pressure, valve-body operation, pulley/belt condition and bearings are key areas when the car judders, slips or whines.

The Honda HR-V is a useful example of why modern Honda transmission terminology matters. Second-generation petrol automatics use Honda CVT, while the current HR-V e:HEV uses a hybrid fixed-gear drive system rather than a conventional belt-CVT.
That means a 2018 HR-V that whines or flares under acceleration needs CVT pressure and ratio testing, whereas a current e:HEV showing a drive warning needs hybrid-system diagnosis.
UK HR-V automatics are mainly split between the Mk2 1.5 i-VTEC CVT and the current Mk3 e:HEV hybrid drive. That makes model year and powertrain the fastest way to choose the correct diagnostic route.
| HR-V generation / type | Typical UK versions | Automatic transmission | What owners often search for |
|---|---|---|---|
| HR-V Mk2, 2015–2018 | 1.5 i-VTEC petrol automatic | CVT with seven simulated ratios | HR-V CVT judder, CVT whine, delayed Drive |
| HR-V Mk2 facelift, 2019–2021 | 1.5 i-VTEC petrol automatic | CVT on relevant UK petrol versions | HR-V gearbox warning, CVT slipping, pressure fault |
| HR-V Mk3, 2021–present | 1.5 e:HEV UK range | e:HEV fixed-gear hybrid drive / automatic hybrid system | HR-V e:HEV transmission warning, hybrid drive fault |
The Mk2 Honda CVT uses continuously variable ratio control with simulated steps. Hydraulic pressure, valve-body operation, pulley/belt condition and bearings are key areas when the car judders, slips or whines.
The current e:HEV uses Honda's two-motor hybrid drive with a fixed gear connecting the petrol engine when appropriate. It is not repaired using the same methods as a belt-driven CVT.
Current HR-V drive behaviour can also be affected by the electric motor, power electronics and hybrid control system, so a drivetrain complaint may sit outside the mechanical fixed-gear unit.
HR-V owners typically search for 'CVT judder', 'CVT whine', 'revs rising without speed', 'delayed Drive' or 'e:HEV transmission warning'. Those searches divide naturally between Mk2 CVT diagnostics and Mk3 hybrid-system checks.
A low-speed judder on a CVT HR-V can involve hydraulic pressure, start-up/lock-up behaviour, fluid condition or engine/driveline movement.
RPM rising without the expected acceleration can point towards incorrect CVT ratio control or internal slip and should not be ignored.
A delay selecting Drive can involve pressure control, valve-body operation or internal clutch application on the CVT generation.
A whine that follows road speed can originate in CVT/final-drive bearings or pulley/belt components, but tyre and wheel-bearing noise should be excluded.
An e:HEV warning may relate to the hybrid motor, power electronics, fixed-gear drive or control system rather than a conventional CVT fault.
Engine speed changing independently of road speed can be normal on e:HEV models; the concern is when it appears with warning lights, reduced drive or abnormal noise.
For an HR-V, the most useful detail is whether the car is Mk2 CVT or Mk3 e:HEV and whether the symptom appears as true slip, road-speed whine, delayed engagement or a hybrid warning.
| What you notice | How drivers describe it | Possible areas to investigate |
|---|---|---|
| Judder pulling away | “It shakes as I move off or reverse.” | CVT/start clutch or torque-converter behaviour, mounts, engine running or driveline |
| RPM rises without speed | “The revs climb but the car does not accelerate properly.” | CVT belt/pulley pressure, internal clutch application or hydraulic control |
| Delay selecting Drive | “I select D and it takes a moment to engage.” | Hydraulic pressure, clutch application, valve body/control or internal wear |
| Whine that follows speed | “It gets louder as road speed rises.” | CVT/final-drive bearings, pulley/belt system, wheel bearing or tyre noise |
| Warning / limited drive | “The transmission or hybrid warning appears.” | Stored TCM/hybrid DTC, sensor/control fault, pressure data or protection mode |
| Hybrid revs feel unusual | “The engine revs do not seem tied to road speed.” | Can be normal e:HEV operating strategy; diagnose only if accompanied by warnings, poor drive or abnormal noise |
HR-V codes are interpreted against CVT pressure/ratio data or e:HEV hybrid-control information depending on generation. A generic transmission warning is not enough to identify the failed component.
| Fault code | What it broadly relates to | What may need checking |
|---|---|---|
| P0700 | Transmission control system warning request | Read the Honda transmission control module for the underlying transmission-specific DTCs |
| P0715 | Input / turbine speed sensor circuit on applicable automatics | Speed-sensor signal, wiring, control data and internal transmission operation |
| P0730 | Incorrect gear ratio / ratio plausibility on applicable transmissions | Commanded versus actual ratio, hydraulic pressure and internal wear |
| P0741 | Torque-converter clutch performance on applicable conventional/CVT automatics | Converter lock-up, hydraulic pressure, control valves and fluid condition |
| P0847 / P0848 | Transmission fluid pressure switch/sensor circuit on applicable Honda automatics | Pressure switch signal, wiring, hydraulic control and transmission pressure |
The Mk3 HR-V e:HEV should not be described or diagnosed as a conventional belt-CVT.
HR-V repair cost is driven by CVT valve-body/pressure work, bearing/final-drive repair, full CVT reconditioning or individual e:HEV hybrid-drive diagnosis.
| Honda HR-V gearbox work | Typical guide range | What can change the price? |
|---|---|---|
| Diagnostic scan and road test | From £30 | CVT versus e:HEV architecture |
| CVT valve-body / pressure-control repair | Approx. £700 - £1,500 | Hydraulic-control and valve-body condition |
| CVT final-drive / bearing related repair | Approx. £900 - £1,800+ | Noise source, bearing condition and extent of damage |
| Full gearbox repair / reconditioning | Approx. £1.8k - £4.5k+ | CVT pulley/belt, bearings and internal damage |
| e:HEV hybrid transmission / drive repair | Diagnosis required | Motor, fixed-gear drive and hybrid-control involvement |
We identify whether the HR-V is a Mk2 CVT or current e:HEV and confirm the exact powertrain.
Honda-compatible diagnostics are used to inspect CVT pressure/ratio data or hybrid-system faults as appropriate.
The symptom is reproduced under the road speed, temperature or operating mode where it occurs.
We then explain whether the repair belongs to the CVT, final drive, hybrid system or another driveline component before quoting.
Tell us whether your HR-V is the 1.5 petrol CVT or e:HEV if known and describe the judder, whine, delayed Drive, slipping or hybrid warning.

Hydraulic pressure, start-up or lock-up behaviour, fluid condition, valve-body control and driveline movement are common areas to investigate on Mk2 CVT models.
CVT/final-drive bearings, pulley or belt-related components can produce a road-speed whine, but wheel-bearing and tyre noise should be ruled out first.
On a CVT-equipped HR-V, pressure loss, ratio-control problems or internal slip can allow engine speed to rise without the expected increase in road speed.
Yes. Valve-body, pressure-control, bearing and internal CVT faults can often be repaired or fully reconditioned if diagnosis shows the unit is viable.
The guide table lists CVT valve-body work from roughly £700–£1,500 and full CVT reconditioning around £1.8k–£3.5k, depending on internal damage.
Not in the conventional belt-CVT sense. It uses Honda's two-motor hybrid drive with a fixed-gear engine connection, so e:HEV faults need hybrid-system diagnosis.
For an HR-V fault, separate Mk2 CVT from Mk3 e:HEV first and then diagnose the pressure, ratio-control, final-drive or hybrid system involved.
